What Is Mandelic Acid?
Mandelic Acid is an alpha-hydroxy acid (AHA) originally derived from bitter almonds, now predominantly produced synthetically for consistent quality. With the CAS number 90-64-2, this aromatic AHA features a larger molecular structure than glycolic or lactic acid, which slows its penetration into the skin and makes it one of the gentlest exfoliating acids available to formulators. It appears in the 2026 ingredient trend charts as a hero active in single-acid serums, with rising consumer search interest across the US, Europe, and APAC markets.
How Mandelic Acid Works
Like other AHAs, Mandelic Acid weakens the bonds between dead corneocytes, accelerating cell turnover and revealing fresher, smoother skin. Its lipophilic aromatic ring gives it a unique affinity for the lipid-rich sebum environment, allowing it to work effectively inside pores where it moderates Cutibacterium acnes growth — a key reason it is favored in blemish-prone skin formulations.
Because the larger molecule penetrates slowly, Mandelic Acid delivers visible texture, tone, and brightening results with significantly less stinging and post-procedure erythema than smaller AHAs. This makes it a first-choice exfoliant for sensitive skin, deeper skin tones prone to post-inflammatory hyperpigmentation, and consumers transitioning from harsh peels to daily-use “gentle acid” routines.
Key Applications
- Gentle exfoliating serums and toners — daily-use acid formulations at 5–10% for sensitive-skin consumers
- Brightening and dark-spot treatments — fading post-acne marks and uneven tone with low irritation risk
- Acne and blemish-prone skin care — pore-level antibacterial action combined with keratolytic renewal
- Anti-aging night creams — smoothing fine texture lines and supporting collagen-stimulating turnover
- Professional peel and in-clinic adjacents — pre-peel primers and home-care maintenance products after dermatology treatments
