Medical-Grade Exfoliants & Peels

What is a medical-grade exfoliant?

Exfoliants remove dead skin cells to reveal smoother, brighter skin and help other products absorb. Medical-grade exfoliants come as chemical exfoliants (AHAs such as glycolic and lactic acid, and BHAs such as salicylic acid) and physical scrubs or polishes, offered by professional brands including SkinCeuticals, ZO and AlumierMD at effective, well-tolerated strengths.

Chemical vs. physical exfoliation

Chemical exfoliants dissolve the bonds between dead skin cells for an even result, while physical exfoliants (scrubs, polishes) buff them away manually. Chemical options are usually gentler and more uniform, making them the preferred choice for most skin types, though a gentle polish can suit those who like the texture.

Choosing your acid

• Glycolic acid (AHA): for dullness, texture and the look of fine lines.
• Lactic acid (AHA): gentler, with added hydration, good for dry or sensitive skin.
• Salicylic acid (BHA): oil-soluble, best for oily, congested or acne-prone skin and blackheads.
• Mandelic acid (AHA): larger molecule, gentle and good for sensitive or deeper skin tones.

Peels vs. daily exfoliants

At-home peels are higher-strength treatments used occasionally for a bigger reset, while daily or weekly exfoliants (pads, toners, gentle acids) maintain smoothness between peels. Start with a lower strength and less frequent use, then build up as tolerated.

How often to exfoliate

Exfoliate one to three times a week rather than daily for most skin.

Signs you are over-exfoliating

Tightness, stinging, redness, flaking or new sensitivity are signs to scale back. Over-exfoliating damages the barrier, so let how your skin feels guide frequency, and always follow with sunscreen, since exfoliation increases sun sensitivity.
