ACTIVE INGREDIENTS · KOJIC ACID
Fermentation-derived brightener for even, settled tone.
Kojic acid is derived from the fermentation process of rice and other starches, a tradition originating in Japanese sake brewing. It inhibits the tyrosinase enzyme that drives melanin production, making it an effective slow brightener for post-blemish marks, sun spots, and uneven tone. OVESSI uses kojic acid in brightening serums at concentrations that accumulate over four to twelve weeks without the harsh fade effect of stronger acids.

Kojic acid questions
Is kojic acid safe for daily use?
Yes, at standard formulation concentrations of 1% to 2%. Some people experience mild sensitivity at first use, particularly if the skin is already reactive. If sensitivity occurs, reduce to alternate evenings and build back up. Always use SPF in the morning when using any brightening active.
How long does kojic acid take to work on dark spots?
Visible improvement in post-blemish marks typically develops over four to eight weeks of consistent use. More established sun spots may require 12 weeks or more. In the OVESSI 28-Day Study, 87% of 68 participants saw a visible tone improvement by day 28, though pigmentation results vary by depth and duration of the mark.
Can I use kojic acid with vitamin C?
Yes. Kojic acid and vitamin C target different points in the melanin production pathway and are synergistic when used together. Apply the lighter, vitamin C step first and follow with the kojic acid formula, or use a combined formula that stabilises both actives together.
Is kojic acid suitable for deeper skin tones?
Yes. Kojic acid is widely used for post-blemish pigmentation and sun marks across all skin tones. It is considered one of the gentler brightening actives because its mechanism is specific to the tyrosinase pathway rather than broad skin lightening. Use at the recommended concentration and frequency.
