Exfoliation involves removing dead skin cells from the surface of your skin to promote a smoother, healthier appearance. You can exfoliate using physical methods, like scrubs or brushes, or chemical methods, such as products containing alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs). It's important to choose a method suitable for your skin type and to exfoliate 1-3 times a week to avoid irritation. Always follow up with moisturizer to keep your skin hydrated.
