Salicylic Acid 2% Face Serum

Salicylic Acid — A beta-hydroxy acid that dissolves oil and dead skin inside the pore, so it's the go-to for blackheads, congestion and oily-skin breakouts. The label states 2%. Works from ~1%. OTC cap 2%. Give it 8–12 weeks for congestion & blackheads. Best for Oily, Combination. An oil-soluble exfoliant — brilliant on oily, congested skin. On dry or reactive skin it can strip and sting, so ease in slowly. Best value: beats 100% of the 6 Salicylic Acid serums that state their strength.

Sodium Hyaluronate — A humectant that holds water in the upper skin — pure hydration, tolerated by essentially everyone, at any concentration. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~1%. Works Ongoing while you use it; no weeks-long build-up to wait for. Suits all skin types. Pure hydration — suits everyone, and dry or dehydrated skin most of all. Apply on damp skin and seal it in.

Glycolic Acid — The smallest alpha-hydroxy acid — it resurfaces the top layer for glow and even tone, working on the surface where BHA works in the pore. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~8%. OTC cap 10%. Give it 4–8 weeks for tone & texture. Best for Oily, Combination, Normal. A surface exfoliant for glow and texture. It raises sun sensitivity and can irritate dry or reactive skin — daily SPF is non-negotiable.

Lactic Acid — An alpha-hydroxy acid with a larger molecule than glycolic — it exfoliates the surface more gently and doubles as a humectant, so it suits AHA beginners and drier skin. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~8%. OTC cap 10%. Best for Dry, Normal, Combination. The gentler AHA — it exfoliates while pulling in water, so dry skin tolerates it better than glycolic. Reactive skin should still ease in, with SPF daily.
