Great question! It is a very good idea to exfoliate the skin at least twice a week, unless your skin is very sensitive, then once a week will be fine. It’s a good idea to play it safe with exfoliation and use a good enzymatic product for the face, such as Lamelle’s Cathepzyme or Nimue’s Exfoliating Enzyme, or Neostrata’s Foaming Glycolic Wash. For the body, it really depends on what you prefer in terms of the feel of your exfoliation, you can use a good body scrub once a week, but then remember this must be followed by a good body moisturiser.
