Immense research has been conducted on AHA’s which has made it clear that frequent exfoliation is essential for smooth, even and hydrated skin—moreover a leave-on AHA product like our 12% AHA/BHA Exfoliating Serum, is considered the best way to exfoliate. 

Starting at the beginning, AHA stands for Alpha Hydroxy Acids, AHA-containing products cause exfoliation, or shedding of the surface skin. They also have a variety of other benefits such as smoothing fine lines and surface wrinkles, improving skin texture and tone, unblocking and cleansing pores, reducing acne, and improving the overall quality of the skin. 

There are multiple AHAs in the cosmetic industry, but the two most common and researched to have proven efficacy are glycolic acid and lactic acid.

When applied to the skin, AHAs stimulate the exfoliation of the superficial surface skin cells by interfering with the ionic bonding (glue) between these cells. In other words, they break down the bonds holding skin cells together. This causes the shedding of rough, aged, dull skin cells and promotes what we like to call “cellular renewal” by increasing cell turnover rates, so you have younger looking and brighter skin cells. 

AHA Exfoliant Tips

• Always use a sunscreen when using an AHA, those newly revealed fresh skin cells and prone to sun damage.
• Don't overuse, it can cause damage to the skin barrier. Recommendation is 2-3 times per week as tolerated.
• Don’t mix with your Retinol (Vitamin A), use these products on alternate nights.
• The most effective range of AHA’s is 3-10%
• Always follow with a moisturiser
