2% Kojic Acid Face Serum with 1% Alpha Arbutin & Niacinamide - 8 ml

Niacinamide — Vitamin B3 — a broadly-tolerated all-rounder that strengthens the skin barrier, evens tone and helps regulate oil. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~5%. OTC cap 10%. Give it 8–12 weeks for tone. Suits all skin types. One of the best-tolerated actives there is — fine for every skin type, and especially handy for oil and uneven tone.

Alpha-Arbutin — A gentle, stable brightener that fades dark spots by slowing melanin production — a milder route to even tone than acids. The label states 1%. Works from ~1%. OTC cap 2%. Give it 8–12 weeks for dark spots. Suits all skin types. A gentle, stable brightener that fades dark spots without the sting of acids — fine for every skin type. Pricey for the %: beats 0% of the 7 Alpha-Arbutin serums that state their strength.

Kojic Acid — A fungal-derived brightener that fades dark spots and melasma by blocking tyrosinase — effective, but strong enough that the EU now caps how much a product may contain. The label states 2%. Works from ~1%. OTC cap 1%. Best for Oily, Combination, Normal. Effective on dark spots but a known sensitiser — patch-test, and if you're reactive, reach for arbutin or azelaic first. Pricey for the %: beats 0% of the 3 Kojic Acid serums that state their strength.
