With lactic acid there is very little, if any visible peeling. Lactic is considered a Very Superficial peel (more of an exfoliation), meaning that it only penetrates into the outermost layer, the Stratum Corneum. It will smooth your skin, and the majority of exfoliation will be on a molecular level. This does not mean that it isn't working though. Flakes are not necessary for changes to occur within the skin. This is the perfect peel for someone that wants refreshed, new and glowing skin, but doesn't want to deal with the dryness and flakes a stronger peel will have.
