AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids) are two types of hydroxy acids used in skincare products to exfoliate the skin and promote cell turnover, revealing smoother, more even-toned skin
. They both work by breaking the bonds holding dull, dead skin on the surface, allowing skin to naturally shed its used-up cells
. However, there are some differences between the two:
- Water-solubility : AHAs are water-soluble, while BHAs are oil-soluble
. This means that AHAs primarily exfoliate on the surface level of the skin, making them suitable for normal to dry skin types
- Benefits : AHAs, such as glycolic and lactic acids, tend to focus their primary benefits around fine lines, wrinkles, and sun damage
. BHAs, like salicylic acid, are generally seen as the milder of the two options and are often used to calm down inflammation and get rid of acne
- Concentration : A product may be less risky if it has an AHA concentration of 10% or less, and a BHA concentration of 1% to 2%
Both AHAs and BHAs can be found in various skincare products, such as facial cleansers, toners, serums, body lotions, and masks
. When choosing between AHAs and BHAs, consider your skin type, goals, and main concerns. If you're looking for an all-inclusive anti-aging treatment, an AHA may be the best fit. A BHA may be better suited if you want to calm down inflammation and get rid of acne
. Always follow the product's instructions and consult a dermatologist if you have any questions or concerns about using AHAs or BHAs
