How to use Galactomyces Ferment Filtrate in a maintenance routine

Where Galactomyces Ferment Filtrate 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).

Galactomyces Ferment Filtrate usually belongs in the “treat” step, but your barrier support is the foundation.

AM or PM: typically used as a first essence or treatment toner after cleansing

Layer before serums and moisturizer

Can be used daily; give it 4-6 weeks to assess tone and texture changes

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
