The best exfoliant depends on the individual's skin type and concerns. Some common types of exfoliants include physical exfoliants, such as scrubs, and chemical exfoliants, such as alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs).
Physical exfoliants use small particles or bristles to physically remove dead skin cells, while chemical exfoliants use acids to dissolve the bonds between dead skin cells.
AHAs, such as glycolic acid and lactic acid, are water-soluble and work well for those with dry or sun-damaged skin. BHAs, such as salicylic acid, are oil-soluble and can be beneficial for those with oily or acne-prone skin.
It's important to note that exfoliating too much can strip the skin of its natural oils and lead to irritation, so it's best to use exfoliants with caution and choose the one that suitable for your skin.
