Facial peels are divided into three main categories;
1. Superficial/light facial peel; this facial peel consists of the application of mild chemical acids to treat problems such as pigmentary changes, fine wrinkling, sun damaged/photo-aged skin or mild scarring. Often used is a low concentration of glycolic or salicylic acid - or another member of this acid group.
Light facial skin peeling is generally safe, effective, and inexpensive. It produces excellent results and enjoys wide patient acceptance. There are usually no significant complications.
2. Medium depth facial peel; this peel comprises of acids such as trichloracetic acid (TCA,) and is commonly used for photoaged skin, warts, and wrinkles. moreover, TCA peels can also remove tattoos over time. Naturally, medium peels will produce improved results over superficial or light peels, but don't expose you to the increased risk of complications associated with deeper peels.
3, Deep facial peel; this chemical skin peeling is usually performed with the more aggressive and toxic chemical such as phenol. Deep chemical peels are used for more severe abnormalities of the skin. They're much more extensive in their procedure and require thorough patient screening and evaluation, as well as intensive training on the part of the physician performing it.
