When it comes to any type of resurfacing such as lasers, chemical peels, or dermabrasion, you should talk to your physician performing the treatment to see what should be used before and after. Failure to follow the appropriate recommendations can lead to prolonged healing and in more severe cases, scarring. Frequently people will be on a retinoid type product before the procedure. After the procedure is when the appropriate topical creams/lotions are the most important, and practitioners will have their favorite products to minimize risks.
I hope this helps and good luck.
