There are lots of variables that come into play to determine the strength of a chemical peel. The ingredient, PH level, how long the chemical peel is left on the skin, how many layers are applied, and weather the peel is lightly applied or vigorously rubbed in all play a role in determining the level of peeling and downtime.
Level I peels have no downtime with zero to minimal flaking, also known as a “lunchtime” peel. These chemical peels are usually alpha hydroxy acid based witch give a lovely glow to the skin and are a great form of exfoliation for skin that feels rough and lackluster.
Level II peels have a higher percentage active ingredient with mild to moderate skin peeling that usually lasts 2-3 days. These peels are typically Jessner’s solutions which contain a blend of resorcinol, lactic acid, and salicylic acid. Best for more corrective and lightening effects compared to a level I peel.
TCA or trichloracetic acid (level III) peel is a medical-strength peel that has the longest peeling time (usually 3-5 days) but also provides the most correction in one treatment. TCA peels are perfect for someone trying to correct acne scarring, severe sun damage, or more advanced signs of aging.
