What is chemical exfoliation? And what are the benefits and drawbacks?
Chemical exfoliation uses chemicals, generally acids or enzymes, to exfoliate the skin. Depending on which acid/enzyme you choose, it can be more or less gentle than physical exfoliation. It really comes down to the formulation of the product. The drawbacks of a chemical exfoliant are often dependent on the product's actual ingredients, the skin condition of the person using that product, and how often that person is using it. There are some chemical exfoliation products that are quite strong and clients are using them way too often. Any exfoliation should be contingent on your specific skin, skin conditions and other products you are using.
What is physical exfoliation? And what are the benefits and drawbacks?
Physical exfoliation involves using a scrub or physical element to exfoliate the face or body with. Some products contain particles that are way too harsh for the face or pieces that are jagged or uneven. Also, there was the whole environmental issue a few years back where plastic micro beads from face scrubs were discovered to be polluting our water system. Generally for the face I do not advise physical exfoliation unless you have thick, oily skin.
AHA vs. BHA, what are your thoughts?
The type of acid you use depends on the individual person and their skin. It is hard to make overarching statements because it is very personal depending on each person's skin. But, generally lactic acid is a safe bet because it is effective yet gentle and can be tolerated by many skin types.
Salt vs. sugar scrub, what are your thoughts?
I wouldn’t use either as a scrub on my face but I love a DIY lip scrub made with sugar and jojoba oil. You can also make a DIY salt scrub with Epsom salts that is fantastic for any of those rough, dry patches on the body.
What do you think is best practice for facial exfoliation?
Less is more with facial exfoliating. In my practice and in New York in general I see a lot of over exfoliation which can cause barrier impairment and other issues. Once or twice a week max is all you need when it comes to exfoliation. When in doubt, reach out to a trusted Esthetician on which product would be best for your skin. The truth is exfoliation is not necessary for healthy skin. Your skin exfoliates itself. If you want a deep dive into skin health and theory, there is a great blog on this topic written by Kristina Holey. I work closely with Marie Veronique and Kristina Holey and everything I know about the skin comes from my work with them.
