Review (3/5): Everything You Want to Know about Skincare Products
There are many things that unspecialized people must be aware of before purchasing and/or using any chemical or even herbal products. Anti aging cream products spread all over the market and many people are not aware of the ingredients, how they work, what are the qualities of a good anti aging cream product, and what are the side effects that such products may pose. You probably know the benefits of Vitamin C serum, but what about the hidden side of it? We know that vitamin C serum a) Acts as an antioxidant, b) Helps produce collagen, c) Restores skin damage. But the other side is often not highlighted from manufacturers. So, to unravel some of the mysteries about skin care products, I would listen to what the experts say about a given product and read scientific conclusions of the effects so that you know what you are doing to your body, skin, etc. In this review, I chose an article from Felicia Rose Labs web that demonstrates the most crucial points that you want to know about before using anti aging cream product. In this article, you will know about such products every thing you want and more; you will be an expert. The review will cover the points below thoroughly:
1. Good versus bad vitamin C for skin
2. Types of vitamin C
3. The safest form of vitamin C
4. The most dangerous vitamin C derivative used in skin serums
I also attached a picture of the most popular brands of aging cream products based on a lab analysis so that people know what is good/effective/healthy and what's not.
** Note that I am not against using skin care products; I just wanted you to know what are they made of and how/when they can be useful or dangerous. Skin care/anti aging products are important to use because every person starts loosing the collagen during 20s; half of collagen will be lost by 30 years old. Collagen is responsible for keeping the skin smooth. I received this product at a discount or for free in exchange with my honest and unbiased review.
===============================================================================================
In this era of profits- over-people, it’s become a health hazard not to closely examine the ingredients found in skin care products. This is particularly true if you’re using an expensive vitamin C serum or cream because the adage “you get what you pay for” tends to make us more trusting than warranted of marketing claims wrapped in fancy packages. While vitamin C is the indisputable champion of anti-aging therapies, most of the vitamin C you’ll find in skin care formulations is a contorted version of the pure active. Many of these derivatives are harmful and found in serums that sell for well over $125 an ounce. Learn about these derivatives to safeguard both face and wallet.
*************Good versus bad vitamin C for skin************
If you had to pick just one skin care active to apply for anti-aging benefits, make sure it’s vitamin C. The reasons are well established in the scientific literature and are summarized in the following four points:
1. Vitamin C enables every step of collagen production from stem cell activity to the structural integrity of the skin matrix.
2. Women experience a loss of collagen integrity and production due to fluctuating estrogen levels (Pugliese 2009).
3. Skin levels of vitamin C drop 425% by the time a person reaches middle age (Shindo 1994).
4. The only way to increase skin levels is to apply vitamin C topically (Levine 2001).
*********Types of vitamin C**********
The following five types of vitamin C are commonly used in cosmetic formulations today. Make a note of their chemical names and check for them on your product’s ingredient list. If you’re not sure about what your ingredient list means,email FeleciaRose or leave a comment and I’ll advise you ASAP.
1. L-ascorbic Acid aka Ascorbic Acid (AA)
AA is the water soluble, biologically active form of vitamin C found in nature. This is the form the body uses to build skin, repair wounds, and protect itself from disease and disorder. Be careful of any vitamin C serum that turns from clear to yellow, tan or brown. It contains AA that’s being oxidized by air and light. Some manufacturers color their solutions orange to hide what’s going on.
2. Magnesium Ascorbyl Phosphate (MAP)
Magnesium-L-ascorby-Phosphate (VC-PMG)
Ascorbic Acid Phosphate (AA2P)
These are different names for essentially the same derivative of AA formed by adding magnesium phosphate in a process known as esterification. The addition of the phosphate raises the pH level ascorbic acid remains stable in when in solution. Sodium ascorbyl phosphate is another vitamin C derivative synthesized to deliver the same benefit.Ascorbic acid naturally occurs at a pH of around 3.5 which is fairly acidic. Its acidity creates problems in emulsions. Emulsions are carriers like lotions and creams formulated to make products look and feel nice. The addition of a phosphate group to ascorbic acid, whether magnesium or sodium, raises the pH level it can survive in to greater than 7.
3. Ascorbyl Palmitate aka Ascorbic Acid-6-Palmitate (AA6P)
This is another ester of AA using palmitate (palmitic acid) to form an oil-soluble molecule. The idea behind creating an oil-soluble derivative is to enhance penetration through the stratum corneum (SC). The SC contains a large number of lipids (fats) by Nature’s design to help keep out pathogens. Lipid soluble (oil soluble) derivatives are proven to penetrate more readily, however there are major problems with making an AA derivate oil soluble. See our post “Why it can be Disastrous to use the Wrong Vitamin C” for details. In the meantime, if you use a product containing ascorbyl palmitate, be sure to stay out of the sun. Under UV exposure, ascorbyl palmitate is toxic to skin cells and contributes to disease states including skin cancer.
4. Ascorbyl Tretaisopalmitate (ATIP)
Tetrahexyldecyl Ascorbate
Ascorbyl tretaisopalmitate and tetrahexyldecyl ascorbate are two names for the same molecule. The first (ATIP) is the chemical name while the second (tetrahexyldecyl ascorbate) is the marketing name. It is likely the marketing name was chosen to disassociate it from “palmitate” which as discussed above, is toxic to skin cells under sun exposure.
5. Liposome Vitamin C
Encasing a molecule in a liposome is a technique devised by cosmetic chemists to impart stability and penetration properties to AA and other molecules. The molecule is wrapped in a bubble of lipids (the liposome) making it oil soluble which is a really bad idea when it comes to vitamins. Worse, chemists use ascorbyl palmitate when making liposome vitamin C. The addition of more lipids (the liposome) may only worsen the ingredient’s toxicity. Please see our post “Why it can be Disastrous to use the Wrong Vitamin C” for details.
*******************The safest form of vitamin C*******************
For the naturalists amongst us, it will come as no surprise that the safest form of vitamin C is ascorbic acid – the form found in nature and biologically active in the body. In 1747 a physician working for the British Royal Navy identified vitamin C as a mysterious compound in citrus fruit that cures scurvy. In 1931 a Hungarian scientist isolated the compound and called it hexuronic acid. The name ascorbic acid was later proposed and adopted to acknowledge its anti-scorbutic (scurvy) properties.
Through common usage, the term “vitamin C” became a categorical name applied to ascorbic acid and its many derivatives. As a dietary supplement, the base ascorbic acid molecule is modified in a variety of ways to either enhance intestinal absorption or reduce its natural acidity. As a topical skin care ingredient, the base molecule is modified to boost its stability and help it penetrate the top layer of the skin. Whether in the form of a dietary supplement or as an ingredient in a skin serum, the biologically active component of any vitamin C derivative is ascorbic acid. Thus the vitamin C compound must be degraded in the skin or in the body so that free form ascorbic acid is released (Humbert 2003).
****************The most dangerous vitamin C derivative used in skin serums****************
While no one intends to sell dangerous products, recklessness is often the road to ruin. In the world of cosmetics manufacturers, the rush to incorporate vitamin C derivatives into formulas sold as anti-aging serums apparently made safety an ancillary concern. Why investigate and look for trouble? What could go wrong with vitamin C?
The poster child for what can go wrong is told in the story of ascorbyl palmitate. Ascorbyl palmitate is a vitamin C derivative formed by adding a fatty acid named palmitic acid to the base ascorbic acid molecule. Fatty acids are building blocks of lipids and palmitic acid is one of the most common. As the name implies, palmitic acid is found in palm trees and coconut oils.
===Palmitic acid is a common fatty acid found in palm tree oils.
++++++++++Lipids and fatty acids are important in skin care because lipids form a major component of the outer layer of the skin. This poses a problem for ascorbic acid because it’s water soluble making it complicated for manufacturers to ensure it passes through the skin’s lipid barrier. An oil soluble derivative was needed and the food industry had already synthesized an oil soluble version to use as a food preservative. Named ascorbyl palmitate, the compound is made by attaching a palmitic acid molecule to an ascorbic acid molecule. One end of the molecule (the AA end) is water soluble and the other end (palmitic acid) is oil soluble.
+++++++++A landmark study reported in the Journal of Investigative Dermatology investigated what happens in human skin when ascorbyl palmitate is applied and then exposed to a moderate amount of sunlight – about the same as an average person would be exposed to on a sunny day.
The researchers expected ascorbyl palmitate to penetrate the lipid barrier of the skin, but they weren’t sure if it would penetrate the lipid barrier of skin cells. They discovered that it efficiently penetrates both lipid barriers, and that the ascorbic acid very effectively subdued intra-cellular free radical generation. However they were astonished to find out that any gains bought by the ascorbic acid were dramatically outweighed by the pitfalls of the palmitic acid. Their astonishment was apparent in the choice of adjectives they used to describe the havoc. According to the authors, palmitic acid is a lightning rod for UV rays which brought on “catastrophic” skin cell death on a “massive scale.” The authors further warned against using any vitamin C serum with a concentration of ascorbyl palmitate in excess of 100-300 M (micromoles). Distressingly, many cosmetics contain concentrations as high as 15 percent which exceeds the authors’ warning dose by a factor of 1000. The number of cosmetics containing ascorbyl palmitate exceeded 617 in the year 2000, a leap from a year 1992 count of 667 products (Burnnet 2011).
Check both your sunscreen and your vitamin C serum for ascorbyl palmitate. The Environmental Working Group is working toward getting the FDA to ban its use in sunscreens. Also check your labels for ascorbyl tretaisopalmitate, tetrahexyldecyl ascorbate and liposome encapsulated vitamin C.
