The Ordinary Mandelic Acid 10% + HA Dupes & Cheaper Alternatives

An 8% mandelic acid serum for gradual exfoliation, pigmentation, and congestion, with panthenol, glycerin, and hyaluronic acid. Redditors reach for it on rosacea-prone skin; studies found mandelic helped mild-to-moderate acne. It remains too shallow for deep pores.

Redditors use this 8% mandelic serum as a preferred active when retinoids are off the table, often stepping up from 5%. The catch is frequency: community advice limits exfoliation to 1–3 times weekly, especially alongside retinol.

A 15% L-ascorbic acid serum paired with tocopherol and ferulic acid for morning brightening and photoaging support. It suits experienced vitamin-C users chasing stubborn pigmentation, but reactive or oily skin may face stinging, tackiness, breakouts, and rapid oxidation.
