Exfoliation removes the outer layers of dead skin cells, helping to brighten and smooth the face, even out pigmentation, unclog pores & reduce the appearance of fine lines and wrinkles. There are two ways to exfoliate: physical (manual) and chemical. With physical exfoliation, you use a tool, such as a brush, a sponge, or a face scrub, to mechanically remove the dead skin cells. Meanwhile, with chemical exfoliation, chemicals (including lactic, glycolic & salicylic acid) gently dissolve the cells.
When you’re ready to exfoliate, do it right after cleansing, either in the morning or evening. If you’re new to exfoliating , start with once a week, working up to twice or three times per week over time. If you find physical exfoliation is too intense, you can opt for a gentler chemical exfoliant (like lactic acid) instead.
