42 % Jessner peel is done by brushing an acidic liquid onto the skin to remove the top layers and encourage new, younger looking skin to grow. While many chemical peels can cause lasting discoloration on darker skin, a recent small study found that a modified Jessner’s solution safely and effectively reduces melasma and pigment imperfections in darker skin. The Jessner peel is typically a medium peel, which means it removes skin cells from the top layer of your skin, the epidermis, and the upper portion of the middle layer, the dermis. However, it can also be used as a superficial peel, which has a faster healing time but needs to be performed more often to get the results of a deeper peel.
