There are so many different kinds of acids used in chemical peels, chemical exfoliations and products – how do you know which ones are right for your skin? This article will explore many of the different acids used in chemical peels and products so you can make an informed choice when purchasing products or receiving a skin care treatment such as a chemical peel.
Alpha Hydroxy Acids (AHA) – many people are familiar with AHA’s. These are water-soluble acids that work to release the desmosomes (adhesions) that hold skin cells together. This causes exfoliation and increased cell turnover. Many of AHA’s typically used in skin care, including chemical peels, also help produce collagen and elastin to firm the skin.
- Glycolic Acid – is naturally found in sugars and has a low molecular weight. Because of its small size, it penetrates into the skin very quickly, sometimes causing irritation and inflammation. It has strong degreasing properties, which is good for oily acneic skin, but not the best choice for chemical peels or products for aging skin, sensitive skin or hyperpigmentation (dark spots or patches on the skin).
- Malic Acid – is naturally found in apples and provides moisturizing and antioxidant benefits. It also helps to tighten pores and reduce fine lines and wrinkles.
- Tartaric Acid – is naturally found in grapes. It is an antioxidant and helps release desmosomes.
- Mandelic Acid – is naturally found in bitter almonds and is helpful in the treatment of hyperpigmentation.
- Citric Acid – is naturally found in citrus fruits. It helps thicken the epidermis and increase hyaluronic acid content in the skin, attracting and holding moisture. It is an excellent acid for anti-aging and skin brightening.
- Lactic Acid – is naturally found in milk and sugars. The larger molecular size of this acid causes it to penetrate the skin slowly, reducing the chances of irritation and inflammation It is antimicrobial and hydrating. It is also a good acid for the treatment of hyperpigmentation.
Beta Hydroxy Acids (BHA) – Typically, the only BHA used in skin care is salicylic acid. Salicylic acid penetrates into oil-filled follicles and breaks down impactions. It normalizes the cell shedding in follicles that contributes to whiteheads, blackheads and pimples. It leaves the skin smooth, with no flaking or peeling.
Azelaic Acid – is an antioxidant and anti-inflammatory, protecting the skin and reducing redness. This is a good acid to use in chemical peels and products when treating acne, rosacea, melasma and post inflammatory hyperpigmentation because of it’s anti-inflammatory properties.
Retinoids – are a vitamin A derivative, with many proven benefits to the skin. They increase cell turnover, help lift pigmentation, reduce impacted acne and are very beneficial for most skin types. In increased percentages, they can increase post-treatment exfoliation, which make them a great add-on to any chemical peel or exfoliation.
When looking at skin care products, read the ingredient label and choose the ingredients that are right for your specific skin type. In chemical peels or exfoliations, a blend of the correct acids will address your specific skin conditions better than one acid alone.
