Head to head
Consider Mandelic Acid if…
An aromatic Alpha Hydroxy Acid derived from bitter almonds or synthetic synthesis. Featuring a larger molecular weight and lipophilic aromatic ring, mandelic acid penetrates the stratum corneum slowly and uniformly, offering gentle epidermal exfoliation, anti-acne antibacterial action, and pigmentation clearance with minimal irritation risk on sensitive or dark skin tones.
- You want a gentle option.
- You're building the prep step of a routine.
- Its current evidence grade is indicative.
Consider Retinol if…
A vitamin A derivative that visibly smooths fine lines and wrinkles and supports collagen production — the most studied active in non-prescription anti-aging skincare, best introduced slowly.
- You want a gentle option.
- You're building the treat step of a routine.
- Its current evidence grade is indicative.
