Many people use wainscoting and beadboard interchangeably, so the terms can be confusing. Here's the difference: Wainscoting is a kind of wood paneling used for centuries as both decorative accents, insulation and to prevent (and cover up) water damage on walls.
When used at 40 percent strength, glycolic peels improve the appearance of fine lines, wrinkles, acne, sun damage and age spots. Considered a superficial peel, 40 percent glycolic peels treat the outer layer of skin, and the results last for up to one month, notes Mayo Clinic.
There are three types of peel: superficial, medium and deep. These have varying percentages of active ingredients and different PH levels. The percentage of a peel just indicates how much of the peeling agent is contained in the peel so a 15% glycolic acid peel has less glycolic acid than a 50% glycolic acid peel.
