~ 14 day rate for a baby
~ 25 day rate till about year of age as adult (30years = 30 days)
Two types of exfoliation

BHA def
Beta hydroxy acid
Exfoliates surface of the skin + inside the pores
Fat/oil soluble
Dries out the skin
Has antibacterial qualities
Tends to reduce inflammation
Exfoliation benefits
Improved skin texture, barrier function, and moisture retention
Increased cell renewal factor
Reduced fine lines, wrinkles, and surface hyperpigmentation
Smoother skin
Improved skin conditions
Possible collagen and elastin stimulation
Exfoliation contraindications
Recent cosmetic surgeries
Recent injectable
Use of skin thinning medication
Allergies or sensitivities to products being used
Pregnancy

Tendency for hyperpigmentation
Inflamed acne or rosacea
