Published in Skin Care Education · Friday 29 May 2026 · 1:00
Glycolic Acid Peel
- Exfoliation boost: Derived from sugar cane, glycolic acid penetrates the upper layers of skin to dissolve dead cells.
- Best for: Dullness, fine lines, mild pigmentation.
- Recovery: Minimal downtime, slight tingling or redness.
Salicylic Acid Peel
- Oil control: Being oil-soluble, salicylic acid dives into pores to unclog sebum and debris.
- Best for: Acne-prone, oily skin, blackheads.
- Recovery: Mild peeling or dryness; avoid if allergic to aspirin.
TCA (Trichloroacetic Acid) Peel
- Deeper resurfacing: Penetrates into the dermis, stimulating collagen and repairing damage.
- Best for: Acne scars, pigmentation, deeper wrinkles.
- Recovery: 1–2 weeks of downtime; requires professional supervision due to risk of pigment changes.
Kojic Acid Peel
- Brightening effect: Derived from fungi, kojic acid inhibits melanin production.
- Best for: Hyperpigmentation, melasma, uneven tone.
- Recovery: Gentle, often combined with other acids for enhanced results.
💡 Key Takeaway
- Glycolic & Kojic → Gentle brightening and tone correction.
- Salicylic → Acne and oil control.
- TCA → Stronger resurfacing for scars and pigmentation.
Always match the peel to your skin type, concern, and tolerance for downtime, and consult a licensed professional before diving in.
