NUMBUZIN No.5 Glutathione C Trace Ampoule 30ml
The glutathione c numbuzin ampoule is a 30ml bottle of the No.5 line's cult brightening treatment. Glutathione, stabilised vitamin C and niacinamide combine in a lightweight watery serum that sinks in fast and gets to work on dark spots, post-blemish marks and overall dullness.
The high-potency formula stays comfortable on sensitive skin thanks to calming panthenol and low-molecular hyaluronic acid. Used morning and night, it visibly evens the complexion and sharpens overall clarity, adding that fresh lit-from-within glow the brand is loved for.
A perfect entry point into the No.5 universe, or a compact daily companion to the pads and masks. Ideal for anyone building a serious K-beauty brightening routine without heavy or sticky textures.
