Key Ingredients
FAQ
Do I use this before or after toner?
Before. This is a booster, which means it goes on clean skin right after cleansing, before your toner or lotion. It preps the skin to absorb the next steps better. If you apply it after toner, you lose the boosting effect.
Does it replace my serum?
No, it's an extra step before your usual routine. Think of it as step 0. You'd go: cleanser, booster, toner, serum, moisturizer. It enhances absorption but doesn't deliver the targeted actives that a vitamin C or niacinamide serum would.
How is this different from SK-II?
SK-II uses galactomyces ferment cultured on rice. Muji uses fermented rice bran extract from Yamagata rice. Both are ferments, but the source and resulting amino acid profile are different. Muji is also 100% naturally derived and costs a fraction of SK-II's price.
