I recently had a client who was on an amazing brand of products. I explained to her different exfoliants.. Enzymes are like gentle pacmen. Lactic acid dissolves the bonds that hold the cells together and is hydrating, being a larger molecule it does not get in as deep as say glycolic, being a lot smaller can go in deeper.. so quite aggressive, fab for rough, dense skin /sun damaged, definitely not for sensitive skin. All amazing but this particular lady had very sensitive skin, a lot of redness and was put on a cleanser and exfoliant by a doctor both with glycolic in it ?
