“To forever look as young as we feel” is what everybody wants, unfortunately aging is inevitable! There are a lot of “miracle” products on the market today, but can you be sure they really work? Glycolic acid, more commonly known as AHA, is an active base ingredient proven effective over the years in cosmetic applications. Since the days of antiquity, people of all cultures have been using glycolic acid for its ability to improve the tone and texture of the skin.
Why use it
AHA is classified as an alcohol acid. This family of acids is a naturally occurring substance found in many fruits and plants, particularly sugar cane, beetroot and grape extracts. This is why these acids are sometimes referred to as fruit acids. Thanks to its small molecular size, glycolic acid can penetrate deep into the skin. It rebalances the skin’s water content, leaving it softer, smoother and more radiant. Also, it reduces the appearance of wrinkles, acne and hyperpigmentation.
Works on the skin, inside and out
The effects of glycolic acid on skin are remarkable. This highly active ingredient works on the upper layer of the skin by weakening interlipid bonding of corneocytes. This promotes desquamation (skin peeling) and an overall decrease in stratum corneum thickness. It leaves the underlying layer looking younger, better toned and more radiant. After 3 to 6 weeks of application, you will notice an improvement in the condition and thickness of the skin. This is due to the renewal of keratinocytes and the increased production of molecules that help to strengthen the resistance of the skin. Following a glycolic acid peel treatment, there is an increased vascularization of the dermis. This improves intercellular exchanges, leading to a brighter, rosier and more even complexion. There is also a notable increase in the production of collagen and elastin.
Concentration levels and pH
Acid concentration level plays an important role in the process of skin rejuvenation. Although glycolic acid at weak concentration levels penetrates only as far as the inner layers of the stratum corneum, it benefits both the epidermis and dermis. At higher concentration levels, the acid penetrates deeper in to the skin, producing a more effective exfoliation. The duration of contact with the skin is also very important. For example, a 70% concentration level of glycolic acid, requires a minimum of 5 minutes for the acid to penetrate as far as the dermal-epidermal junction. More than 10 minutes can harm to the skin. The pH level is also a factor; the lower the level, the better the results. Last but not least, one must consider the client’s skin type. A thick oily skin type allows for longer treatment times and higher concentration levels. Upon application, the client feels a warm and slightly tingling sensation. Glycolic acid based products should not be used all year long. They are recommended only when a skin cure is required, and preferably right before bedtime!
Glycolic acid, on its own, can be considered an active cosmetic ingredient, able to treat many skin types. Simply curious or already convinced? Do you want to try it out?
