What is Hydroxy Acid?
Hydroxy acids function to smooth, tighten, firm and brighten. They encourage stimulation of healthy new skin cells as they encourage exfoliation, can also function beneath the skin's topical layer to penetrate the epidermal and dermal layer. Overtime, these acids are proven to be effective and observers that use these acids typically consistently notice a significant difference in their skin's smoothness as it works to exfoliate.
Alpha and Beta Hydroxy Acids
Hydroxy acids fit into 2 categories, alpha and beta. Alpha hydroxy acids are known as (AHAs) and Beta hydroxy acids, known as (BHAs). Both groups are naturally derived from different food types, and plant-based sources. They both work similarly, yet result in 2 different outcomes. AHAs are water soluble and BHAs are lipid soluble, which means its more effective on oily skin.
Both AHA and BHA diminish the look of fine lines and wrinkles, make the skin feel more firm, while brightening and hydrating the skin.
- Glycolic acid (derived from sugar cane)
- Malic acid (made from apples)
- Lactic acid (sour milk derived)
- Mandelic acid (made from almonds)
- Tartaric acid (derived from grape wine)
- Salicylic acid
The skin needs to get used to the acid, so it's best to do a patch test first, or use in small concentrations to prevent redness or irritation.
