Serum with mandelic acid

Choose based on concentration, hydration, and your primary skin goals. For sensitive or dry skin, opt for milder 5% mandelic acid formulations with hyaluronic acid, commonly found in brands like REVOX or nineless, and start with 2–3 applications per week. If you want brighter tone and more exfoliation and your skin tolerates actives well, a 10% mandelic acid + HA serum is suitable, but introduce it gradually and avoid daily use at first.

Concentration and hyaluronic acid presence determine exfoliation strength and hydration. Mandelic acid has a larger molecular size than glycolic acid, so even higher percentages can be gentler; 5% yields mild exfoliation suitable for beginners, while 10% delivers stronger benefits for more resilient skin. When HA is included, the serum helps retain moisture, reducing dryness and irritation.

A beginner with sensitive or dry skin should start with a 5% mandelic acid + HA serum and limit usage to a few nights per week. A more experienced user with tolerant skin or with discoloration can consider a 10% + HA formula or layering with other actives, but proceed cautiously and monitor skin.

Patch test before first use to check tolerance. Apply at night after cleansing, wait 1–2 minutes, then moisturize; always use sunscreen during the day. Avoid mixing with strong actives like retinoids on the same night; store in a cool place away from direct sunlight.

Brands such as REVOX, nineless, Molecule-Clear, and uncover include mandelic acid serums. To pick, consider concentration (5% vs 10%), presence of hyaluronic acid for hydration, and packaging quality for stability.

Mandelic acid serums are generally gentler than other AHAs, but sensitivity varies; start with patch test and a low-frequency schedule. If you have active eczema, open wounds, or are pregnant or nursing, consult a dermatologist before use.
