The Acids — Ingredient Science
The chemistry of each peeling agent — AHAs, BHAs, TCA, Jessner's, retinoids, depigmenting actives, and why concentration and pH govern results.
- AHAs: Glycolic, Lactic, MandelicHow molecular size and water affinity differentiate glycolic, lactic, and mandelic acids.
- BHA: Salicylic AcidWhy salicylic acid's lipophilicity makes it the comedolytic BHA of choice for oily, acne-prone skin.
- TCA & the CROSS TechniqueUsing high-strength TCA focally via the CROSS technique to remodel atrophic scars.
- Jessner's & Combination PeelsHow Jessner's solution and layered combinations extend depth while controlling risk.
- Retinoids in Peeling (the Yellow-Peel Science)The biology behind retinoid-based yellow peels and their delayed, pigment-friendly exfoliation.
- Depigmenting Agents: Kojic, Arbutin, TranexamicHow kojic acid, arbutin, and tranexamic acid suppress melanogenesis as peel adjuncts.
- Concentration & pH: Why Disclosure MattersWhy free-acid value and pH — not concentration alone — determine real peel potency.
