Matters taken into consideration when selecting the actual depth of the peel include: the amount of time the solutions remain on the skin and whether or not they are lightly, heavily or vigorously applied. In terms of which peel procedure is the most common, it is one involving the application to smooth rough skin to assist in the combat of acne.
