Exfoliating is the process of removing dead skin cells from the surface of the skin. This can be done using physical methods, like scrubs or brushes, or chemical methods, such as products containing alpha hydroxy acids or beta hydroxy acids. Regular exfoliation can help improve skin texture, unclog pores, and promote a brighter complexion. It is generally recommended to exfoliate the skin 1-3 times a week, depending on skin type and sensitivity. Over-exfoliating can lead to irritation or damage, so it's important to choose the right method and frequency for your individual skin needs.
