Ingredient Layering
Can I Use Glycolic Acid and Retinol Together?
Best to Avoid
Glycolic Acid and Retinol should generally not be used together.
What You Should Know
- •Both increase cell turnover — combined use risks over-exfoliation and barrier damage
- •If you want to use both, apply them at different times of day (one in AM, one in PM).
- •Always introduce one ingredient at a time and monitor your skin's response.
exfoliant aha
Glycolic acid is the smallest AHA molecule, which means it penetrates skin more effectively than its counterparts. It dissolves the bonds between dead skin cells, revealing smoother, brighter skin underneath. Among chemical exfoliants, it has the deepest evidence base.
retinoid
Retinol is the single most evidence-backed anti-aging ingredient in skincare, full stop. Decades of research confirm it accelerates cell turnover, stimulates collagen production, and treats both acne and photoaging. The catch: it requires patience and a smart introduction strategy.
