FREQUENTLY ASKED QUESTIONS

Is Numbuzin No.5+ serum suitable for sensitive or acne-prone skin?

Yes. The serum is alcohol-free, fragrance-free, silicone-free, and fungal-acne safe. It’s gentle enough for sensitive and blemish-prone skin, with ingredients like panthenol and ceramide NP soothing inflammation while ceramides and glycerin support the skin barrier.

Does it oxidize like other vitamin C serums?

No — Numbuzin uses a stable derivative of vitamin C, so it’s less prone to oxidation compared to traditional L-ascorbic acid serums. Keep the bottle away from direct sunlight and store it in a cool, dry place to preserve freshness.

Should I keep this serum in the fridge?

It is not required, but storing it in a cool, dark place (or fridge) can help keep the vitamins fresh and provide a soothing application experience.
