Top 5 Most Misleading Cosmetic Claims- Part 5

Understanding "Helps" Claims

There are two categories recognized for cosmetics; cosmetics and drugs.
  • Cosmetics- products intended to be applied to the human body for cleansing, beautifying, promoting attractiveness or altering the appearance.   
  • Drugs- products intended for use in the diagnosis, cure, mitigation, treatment or prevention of disease in man. 
 A drug product is subject to registration, testing, labeling and packaging requirements that a cosmetic product is not. Since by definition a drug product is intended to treat something the claims that can be made on a drug product are substantially different than a cosmetic product. A drug product has an active ingredient that is recognized as a treatment for a disease or condition by FDA. For example, acne treatments. Here are the claims for Neutrogena Rapid Clear Acne Defense Face Lotion:

Contains maximum-strength acne-fighting medicine with botanical extracts to fight existing acne, help prevent future breakouts and leave skin feeling soft. This lightweight, daily lotion fights the multiple symptoms of acne. A powerful formula contains soothing natural botanicals to help prevent irritation, peeling or dryness. Powerful Salicylic Acid fights acne fast, penetrating deep into pores to unblock dirt and oil while sweeping away dead surface cells that can cause future breakouts.

The monograph for the active ingredient- salicylic acid- defines what you can say about the product. Salicylic acid is recognized as a treatment for acne and it functions by exfoliating the skin of dead skin cells which can block pores and cause acne. Botanical ingredients are not recognized as a treatment so any claim related to them must include the word helps.

Of course cosmetics companies want you to believe that a cosmetic (not drug) product is going to do something for you otherwise why would you buy it? So they couch their claims with words like "helps" and "reduces the appearance" and this is where it gets misleading. Here are the claims for Estee Lauder Time Zone Line and Wrinkle Reducing Creme:

Now you can take more than 10 years off the look of your skin in just 4 weeks and dramatically reduce the look of wrinkles. We can prove it. In fact, this anti-wrinkle moisturizer is so powerful, every single woman tested showed a reduction in the look of wrinkles.

That sounds great, right? If you read carefully, they only claim a reduction in the "look" of wrinkles not and actual measurable reduction in the number or depth/ length of wrinkles.

In 2005, Strivectin introduced their "better than BOTOX" stretch mark and wrinkle creams. These were cosmetic products but they were literally COVERED in claims. They claimed things like:
  •  Decreased the actual length of striae (stretch marks)
  •  Decreased the depth of indented surfaces
  •  Actually reduce the size of saddle bag thighs
  •  One problem area at a time, until you've literally melted the fat and molded your body into a more pleasing shape
And so on. It was ridiculous. No drug does the things that they claimed let alone a cosmetic. But it sold their product. Then the customers did not get the results that they claimed and they were understandable mad because these were not cheap lotions. FDA sent them a warning letter http://www.fda.gov/ICECI/EnforcementActions/WarningLetters/2005/ucm075254.htm and forced them to withdraw all of the false claims from the market. StriVectin reformulated (or repackaged I don't know for sure) but their claims are much more subdued now because they are just selling lotion and no mater what the package says- there are no miracle lotions.

Read the packaging carefully and critically. Don't be a sucker for a pretty package that says great things.

HYPOALLERGENIC COSMETICS

When you see a product labeled as "hypoallergenic" you would think that this means that the product is less likely to cause allergic reactions than similar products without this designation. Unfortunately, you would be wrong. According to FDA there are no federal standards or regulations that apply to the term "hypoallergenic". The decision to use the term lies solely with the manufacturer and may be used without any proof that the product causes fewer allergic reactions than others.

Decades ago, a lot of harsh ingredients were used in cosmetics. Today, what can and can't be used in cosmetics is highly regulated so the ingredients available to a cosmetics company are limited and all the same. When using the term "hypoallergenic" became popular in 1975, FDA tried to regulate the use of the term, stating that a cosmetic product could be labeled "hypoallergenic" only if scientific studies on human subjects showed that it caused a significantly lower rate of adverse skin reactions than similar products not making such claims. However, this regulation was struck down by US courts and manufacturers were free to say "I DO WHAT I WANT!"

At my company, we do RIPT (Repeat Insult Patch Testing) on every product that we sell for our own peace of mind (and to protect the company from law suits). An outside testing company gets a collection of volunteers who have the product applied to their skin for a predetermined amount of time and then evaluated for skin reactions. Our products have never shown any adverse reactions but we still do not label our products hypoallergenic.

The bottom line here is that labeling a product hypoallergenic means nothing and the company is not obligated to perform any testing in order to use this label.

Cosmetics companies want you to believe that they have the answer to fine lines, wrinkles, sagging skin and stretch marks. Just put this cream on and the appearance of fine lines and wrinkles will be visibly reduced! Technically- that statement is true. If you moisturize your skin, the fine lines and wrinkles will plump up and they will appear to fill in. This does not mean that you will have any real reduction in wrinkles. It just means that if you use this product (and continue to use it) your wrinkles will look better.

Sadly, most consumers expect that a wrinkle cream will make their wrinkles fade away and disappear. Unfortunately there is no lotion, serum, cream, or oil that can reverse the effects of age and gravity on our bodies. The only thing that can do this is plastic surgery. A cream that says it will "help" tighten and tone your sagging skin may have and ingredient in it that tingles or feels tight so that you know its "working". Wrinkle serums frequently contain plumpers like pepper extracts which are really just irritant to your skin. They cause inflammation and swelling, or plumping. There is nothing that can penetrate the skin layers all the way down to the snapped elastin fibers and make them grow back together to heal your stretch marks. (I sure wish there were!!) The best any cream can do for you is have skin lightening ingredients to help the redness fade away- which time will eventually do by itself.

Women spend a lot of money on products that claim to be "Better than Botox!" but you should really just save that money for the real thing.

Top 5 Most Misleading Cosmetic Claims- Part 2

CHEMICAL IS NOT A DIRTY WORD!

Which brings us to Number 2 on my list of misleading cosmetic claims: Chemical-free.
First let me reiterate what I have said many times: everything in this world is a chemical, even you, even water. We are all just complicated combinations of chemicals. So that said- no cosmetics are chemical free. When you see this claim you should immediately dismiss the product- it's an outright lie.

Along the same lines as "chemical-free" products, products that have a "Free From:" and a long list of supposedly "bad" chemicals are almost as bad. A good example of a company that does this is Origins. www.origins.com Their "purity" statement says "Our products are formulated without parabens, phthalates, propylene glycol, mineral oil, PABA, petrolatum, paraffin, DEA and animal ingredients. Why is it so important to know all of the things that the are NOT putting in their products instead of telling you what they DO put in their products?
1) Ginger Extract- data shows taking ginger orally has anti-oxidant and anti-carcinogenic benefits. Applied topically- it's a major skin irritant.
2) Lemon (and all citrus) oils- classified as irritants and potentially phototoxic (cell death with light exposure)
3) Mint- irritant
I could go on and on with the number of irritating essential oils included in the Origins line. Their tagline is using all natural plant oils but not all plant oils are good for your skin! Many are downright bad for it! Besides all of this, after a lot of digging I found an ingredient statement for their Have A Nice Day Supercharged Moisture Sunscreen SPF15 and found that they did indeed use parabens! There is nothing wrong with parabens (they are a much vilified ingredient as I explained in a previous post) but Origins made a specific statement that they DO NOT use them.

I've also seen products that have a "free from" section a mile long with ingredients that would never be included in that type of product. For example, a facial moisturizer claiming to be free from Sodium Lauryl Sulfate (SLS). What formulator in their right mind would put a detergent in a lotion?!

I think it is far more important to be aware of what is IN your products than what is not. I can make a preservative free product too. In another month you'll get the added ingredients of bacteria and mold! Enjoy smearing that on your face!

Top 5 Most Misleading Cosmetic Claims- Part 1

Let's talk about "All Natural" products.

First of all, there is no specific definition of what is required to label a product as "all natural". Any company can use this term on any product. It's a marketing tool- plain and simple. The company wants you to believe that this product is some how better for you that it's "non-natural" counterpart. It's not true.

Here is a good example of an "All Natural" product from Burt's Bees. This is the INCI ingredient statement from their Natural Acne Solutions Daily Moisturizing Lotion:

Active Ingredients: Salicylic Acid (1.0%), Other: Water, Helianthus Annuus Seed Oil (Sunflower), Glycerin, Stearic Acid, Sucrose Distearate, Salix Nigra Bark Extract (Willow), Sucrose Stearate, Cymbopogon Schoenanthus Extract (Lemongrass), Hamamelis Virginiana Water (Witch Hazel), Humulus Lupulus Extract (Hops), Equisetum Hiemale Leaf Extract (Horsetail), Hydrastis Canadensis Extract (Golden Seal), Epilobium Fleischeri Extract (Gravel Willow), Lecithin, Chrondrus Crispus Extract (Carrageenan), Fragrance, Glucose, Xanthan Gum, Sodium Borate, Sodium Chloride, Glucose Oxidase, Lactoperoxidase

Burt's Bee's will tell you that this is an all natural product because their salicylic acid is derived from white willow bark extract. Salicylic acid is salicylic acid- where it was "derived" from makes no difference. What about all of the other ingredients in this product? The product claims to be 100% Natural but I don't know how glycerin, fragrance, or stearic acid can be considered natural. While there is nothing harmful in this product, as an acne sufferer for my whole adult life, this would not be a product I would use to treat my face. It's main ingredient is Sunflower Oil. For oily skin? Why would I want to add more oil to my oil plagued skin? It also leaves a tacky, waxy feeling on the skin (due to the choice of emulsifiers). Finally the product is well above the pH range for the salicylic acid to function as an exfoillient. These are things that make my skin break out more.

By contrast here is the INCI Paula's Choice Skin Perfecting 2% BHA lotion:

Water, Methylpropanediol, Butylene Glycol, Polysorbate 20 , Salicylic Acid , Phytosphingosine , Hydroxyethylcellulose , Vitis Vinifera (Grape) Seed Extract , Camellia Sinensis (Green Tea) Flower/Leaf/Stem Extract Epilobium, Angustifolium (Willow Herb) Flower/Leaf/Stem Extract,  Bisabolol , Sodium Hydroxide , Tetrasodium EDTA

Paula's Choice does not claim that this product is all natural. It contains the same active ingredient, four naturally derived anti-irritants, two glycol solvents that aid penetration of the actives, a pH adjuster, an emulsifier, a plant derived thickener and preservative and a chelating agent. Nothing in here is bad for you in any way. This lotion is lightweight and absorbs quickly. It's formulated in the correct pH range for the salicylic acid to function as an exfoillient.

I have no aim to villainize Burt's Bee's or promote Paula's Choice. My mission here was to point out that an "all natural" claim:
1) Means nothing as there are no regulations on labeling something "all natural"
2) Natural does not mean good for your skin. Arsenic is natural. Lead is natural. Both of these were used in the Middle Ages and poisoned and killed many women.

Again I would like to point out that there are ZERO "chemical-free" products as EVERYTHING is a chemical, even water. Cosmetics and personal care companies are not looking to poison their customers. If we killed everyone who would buy our products?

Water Wipes- perhaps mold wipes would be a more appropriate name

Last night, I was harvesting my crops on FarmVille like always and I look to the right and there is this ad from WaterWipes USA. Basically their ad says 100% Chemical Free! As a chemist I was instantly annoyed.


The product is a baby wipe moistened with 99.9% water and 0.1% grapefruit seed extract. This is the link to their facebook page: http://www.facebook.com/WaterWipesUSA and their company website: http://www.dermah2o.com/ I was in a bit of a snarky mood so I went to their Facebook page and left a comment. "Dihydrogen Monoxide is still a chemical." These kind of claims always make me mad. EVERYTHING on this earth is made from chemicals. NOTHING is "chemical-free". Companies that make these claims are pandering to the ignorant and scientifically illiterate people who suffer from chemo-phobia.

Obviously I am a cosmetic/ personal care chemist, but I am also a mom. I had a natural, unmedicated birth but I would never even think of not having my child vaccinated. I breastfed but when I went back to work, Sarah gave her pumped milk in bottles made with BPA. I grow my own vegetables and can them myself too- but I use fertilizer and pesticides in my garden and on my fruit trees. Basically what I'm saying is this- look at the data, evaluate the source of the data and then determine whether you need to avoid chemical X or Y.

The biggest hype about this product is the worst of all- the fact that it is preservative free. The 0.1% GSE is SUPPOSED to be there as a preservative but as I have learned through research for work- GRAPEFRUIT SEED EXTRACT IS NOT A PRESERVATIVE!!! If you don't believe me look for yourself:
http://www.ncbi.nlm.nih.gov/pubmed/10399191
http://www.naturalingredient.org/Articles/Report0520.pdf

I'll summarize it here. There are no regulations for how GSE is manufactured. Most GSE has has been preserved by another preservative (i.e. parabens, benzethonium chloride, etc). When tested, the GSE samples in which no preservative can be detected show no anti microbial activity. In other words, if you leave a pack of these wipes open, and some mold spores float into the package, you will have created the perfect petri dish to grow that mold because there is NOTHING in here to prevent it. Since this product is for cleaning babies butts- a place where bacteria is plentiful- imagine if you were wiping up a big mess and some got on your fingers and you reached for another wipe. Now you have inoculated your package of wipes with fecal coloform bacteria- or E.Coli- where it will grow and multiply unchecked. Preservatives keep products from going rancid, and growing mold and bacteria. There is no data linking parabens to breast cancer or any other type of cancer. Check out the American Cancer Societies position on parabens: http://www.cancer.org/Cancer/CancerCauses/OtherCarcinogens/AtHome/antiperspirants-and-breast-cancer-risk basically, they say that there is really no connection between the two and that the study "linking" them was a poorly designed study.

If all of this isn't enough to convince you that this product is a terrible idea, the price for a pack of wipes is $4.99. $4.99 for a package of washcloths moistened with water. If you have a sensitive skinned baby, wet a washcloth in the sink and wipe your baby's butt with it. At least you can wash it out when you are done. There a lot of reasonable options for disposable baby wipes for babies with sensitive skin.
Pampers Sensitive Skin wipes do not have any alcohol, fragrance or dyes (the main contributors to skin sensitivity) but they are still well preserved.
Huggies Natural Care- fragrance free (all the same reasons as above)
BabyGanics Thick n Klean wipes a more expensive option but it does have an effective preservative, plus they claim a biodegradable status and have no parabens if you are still worried about that
Walgreens Comfort-Smooth Baby wipes with Aloe (unscented) almost the same product as BabyGanics except they make no claim about the biodegradability and they are half the price.

There are literally hundreds of valid options for gentle, disposable wipes that are also well preserved. I don't know about you but I would rather wipe my babys' butt with a well preserved wipe than mold. Hell, I would rather wipe her butt with just about anything besides these terrible wipes!

So, you want to make a sugar scrub.

Sugar or salt scrubs are one of the simplest things you can make for your skin. If you have dry skin, they are great for moisturizing. In my opinion, sugar and salt scrubs are too harsh for the skin on your face but can be wonderful for rough areas like your hands, feet, knees and elbows or to exfoliate your legs prior to shaving.

Making a sugar scrub is something you can easily do at home with ingredients from the kitchen. Really you only NEED two things- an oil and a sugar. Pour some oil in a bowl and add enough sugar until it gets to the consistency you like in a scrub.



Now, there are a lot of ways you can fuck this up and a lot of ways you can make it fancy. Here are some guidelines of stuff NOT to do when making your own sugar scrub.

1) Don't add anything that contains water or is water soluble. This includes any type of juice or extract (unless extracted in oil, unlikely to find in your house).
2) Don't add a bunch of sugar to hand soap and expect it to stay a scrub- the main ingredient in liquid soap is water!

The reasoning behind items 1 and 2 is that sugar and salt dissolve in water! It may start out a scrub but over time, the sugar or salt crystals WILL dissolve and you will be left with a very sugary or salty liquid! There is NO getting around this. A scrub with a water soluble scrubber (like salt or sugar) HAS to be anhydrous!

3) Don't add citrus oils or other irritating essential oils. The whole premise behind the anhydrous (without water) scrub is that you scrub loose any dead skin, etc and leave behind a nice moisturizing layer of oil. Citrus oils are phototoxic, meaning that when they are exposed to sunlight they kill your cells (resulting in a bleaching effect, which is why so many skin lightening products have citrus oils in them) but it's not healthy for your skin. So unless you're exfoliating your lady garden (or other areas that never see the light of day) leave the citrus oils out!

OK, now that I've covered what not to do, here's a few tips on what TO do!

1) Pick an oil that you love. There are literally hundreds of choices here. Some are substantially more expensive than others or significantly harder to get but if you have heard of it, it's out there. Some that are commonly available in grocery stores are: canola, corn, peanut, avocado, coconut, grapeseed, sunflower, olive and sesame. Personally, I like a lightweight oil so my choice would probably be grapeseed. If you have really dry skin you should pick something a little heavier like avocado, sunflower, olive, corn, canola or sesame (peanut if you don't have allergies). The only one that I would personally never use is coconut. Coconut oil is comedogenic, meaning it clogs pores and makes acne worse. I have acne issues, not just on my face but occasionally on my chest and body too- so I avoid coconut oil at all costs. If you don't have issues with acne go ahead and give it a try- it smells great!

2) Once you've picked your main carrier oil, consider purchasing a small amount of a more exotic oil or an oil soluble extract. Again the possibilities here are endless and the interweb is your friend.

Finally, if you want to get a little bit fancy, try making an emulsified scrub. All you need to make a sugar scrub into an emulsified sugar scrub is.... an emulsifier! :) Emulsifying wax (E-wax) is readily available from multiple suppliers on the internet. Emulsified scrubs are still anhydrous but when you are scrubbing your wet body part with it, it forms a microemulsion on your skin and feels like a lotion when you rinse it off. They are also easier to rinse off, don't feel as oily and don't leave a super slick, hazardous tub behind!
The recipe for an emulsified sugar scrub goes something like this:
10g E-Wax
90g oil of choice
Melt E-Wax in to oil in a double boiler
To this add as much sugar as necessary to create the desired level of scrubbiness (probably at least 100g)!

Also, since I've harped on this on my blog before, you actually do not NEED a preservative in this formula. Microorganisms need water and this doesn't have any. That said, dipping wet hands into a tub of sugar scrub CAN introduce bacteria and the water necessary, so a preservative wouldn't hurt. If you don't want to use a preservative, don't make a lot and store it in the fridge just in case. All oils do go rancid after a time, some faster than others. Keep this in mind when choosing your oils and if your scrub starts to smell funny- THROW IT OUT!

A well made sugar scrub is a quick and easy gift idea for any lucky person in your life. Just spoon it into an appropriate container and finish it off appropriately!
