How to use Kojic Acid in a maintenance routine

Where Kojic Acid fits, how often to use it, and what to pair it with for barrier-first consistency.

Where it fits in your routine

Cleanse (gentle) → hydrate → treat (optional) → moisturize → sunscreen (AM).

Kojic Acid usually belongs in the “treat” step, but your barrier support is the foundation.

PM preferred (to avoid daytime instability): cleanse → kojic acid serum → moisturizer

Start 2-3 times/week and increase if tolerated

Always pair with SPF 30+ in the morning; pigmentation actives without sunscreen are pointless

Can be combined with vitamin C or niacinamide for layered pigmentation support

Glycerin and humectants for comfort

Ceramides for barrier reinforcement

Sunscreen in the morning if you’re targeting long-term aging well

Multiple exfoliants at once

Strong acids + strong retinoids in the same routine until you know your tolerance

Fragrance-heavy formulas that make it hard to interpret reactions
