ZO Peels

A medically supervised chemical exfoliation treatment developed under Dr. Zein E. Obagi’s ZO Skin Health brand, using formulations of acids (such as salicylic acid, lactic acid, trichloroacetic acid) and potentially adjunctive agents (e.g. retinol, calming/crème elements) to remove damaged superficial skin layers, stimulate deeper epidermal and dermal cellular turnover (including collagen stimulation), improve texture, tone, pigmentation, and other skin irregularities. The intensity, depth, and recovery (“downtime”) depend on the specific ZO Peel protocol, and are tailored by a skin professional to the person’s skin type, condition, and pre-/post-care.

SkinCeutical Peels

SkinCeuticals defines its chemical peels as professional treatments performed in-office by licensed skincare experts whose purpose is to exfoliate or resurface the outer layer of skin in a controlled way, revealing newer, healthier skin underneath.

These peels use various acid formulations—such as alpha hydroxy acids (AHAs), beta hydroxy acids (BHAs), and trichloroacetic acid (TCA)—chosen and adjusted according to the individual’s skin type, concerns, and tolerance.

The treatments are intended to address issues like fine lines, wrinkles, uneven skin tone, acne or blemishes, enlarged pores, pigmentation and dullness.

They vary in depth and strength: from superficial peels (gentler, less downtime) to medium depth peels (more aggressive, longer recovery).

Finally, SkinCeuticals emphasizes that effective results depend not just on the peel itself, but also on proper preparation of the skin in advance, correct application by a professional, and thorough aftercare (especially sun protection).
