WHAT ARE THEY?
Hydroxy Acids are naturally-derived compounds that exfoliate surface cells and encourage cell turnover, helping skin to look and feel younger. There are 2 main types: Alpha-Hydroxy Acids (AHAs) and Beta-Hydroxy Acids (BHAs). Poly-Hydroxy Acids (PHAs) are a special type of AHA.
WHAT DO THEY DO?
Hydroxy Acids accelerate our skin’s natural exfoliation (shedding) process by loosening the bonds that anchor dead skin cells. Skin exfoliation slows down as we age, and the presence of excess dead skin cells can lead to the appearance of dry and dull skin. Also, when these dead cells plug skin pores, the skin can appear bumpy. The use of Hydroxy Acids helps to reveal new healthy skin cells, which can improve skin’s appearance.
Alpha-Hydroxy Acids (AHAs) such as Lactic Acid (from Ammonium Lactate) and Glycolic Acid effectively accelerate exfoliation, while also providing moisture to the skin.
Beta-Hydroxy Acids (BHAs) such as Salicylic Acid are oil soluble, and can therefore exfoliate within skin pores. Also, BHAs can reduce skin inflammation and function as anti-microbials.
Poly-Hydroxy Acids (PHAs) such as Gluconolactone have a unique chemical structure that attracts more water and thus provides enhanced moisturization. PHAs are great for sensitive skin since they can exfoliate without irritation. They also function as anti-oxidants.
WHAT ARE THEY GOOD FOR?
Hydroxy acids are ideal for very dry and aging skin since they moisturize and encourage skin cell turnover. They are also great for softening rough and/or bumpy skin.
