Known Interactions
Retinol combined with Glycolic Acid significantly increases irritation potential. The low pH required for Glycolic Acid (pH 3.0-4.0) destabilizes Retinol. Use in separate products.
Glycolic Acid's low pH (3.0-4.0) can convert Niacinamide to nicotinic acid, causing flushing and reduced efficacy. Use in separate products or buffer the pH above 4.5.
Low pH from Glycolic Acid can destabilize the copper-peptide bond, releasing free copper ions. Use in separate products.
Combining AHA (Glycolic) and BHA (Salicylic) at full concentrations significantly increases irritation risk and can compromise the skin barrier. If combining, reduce concentrations of both.
Tretinoin and Glycolic Acid together cause severe irritation, dryness, and barrier damage. Use in separate routines.
Adapalene combined with Glycolic Acid increases irritation risk. While Adapalene is more stable than Tretinoin, the exfoliation synergy can compromise the skin barrier.
