Alpha-hydroxy acids (AHAs) are the first generation of hydroxy acids mainly used for non-sensitive skin. They can have anti-aging effects on all levels of the skin, including superficial exfoliation and dermal remodeling. AHAs, also known as fruit acids, are a group of acids naturally found in fruits and foods.
Salicylic acid, known for its exfoliating properties, is currently used to treat plaque psoriasis by reducing flakes. However, salicylic acid can thin the dermis and worsen skin atrophy induced by topical corticosteroids. On the other hand, AHAs can enhance dermal biosynthesis and counteract corticosteroid-induced dermal thinning. Both AHA and BHA products are recommended for twice daily use. AHA is well tolerated and effective as an exfoliant. It is preferred over salicylic acid when combating corticosteroid-induced dermal thinning.
Lactic acid and glycolic acid are common superficial peeling agents in the AHA compounds for superficial skin resurfacing. Compared to other chemical peels such as trichloroacetic acid and salicylic acid, AHAs have significant advantages as resurfacing agents. AHAs are safe and effective for all skin types and most treatment cases. High-strength (up to 70%) free AHA peels without pH adjustment can be quickly applied for skin peeling to accelerate epidermal and dermal renewal. These high-intensity AHA peels require localized treatment in a doctor’s office for various skincare needs, anti-aging, and skin smoothing. Medium-strength AHA peels (e.g., up to 7% concentration) can be used in spas and salons for beauty treatments, while home use AHA peels typically have concentrations and pH levels around 3%.
Acidic substances like AHAs and salicylic acid should be used steadily after establishing tolerance. They play a crucial role in improving our skin’s oil-water balance. Choosing products suitable for individual needs is key to personalized skincare routines!
