NUMBUZIN No.5 Glutathione C Trace Ampoule Double Pack (30ml x 2)
The glutathione c ampoule numbuzin double pack pairs two full 30ml bottles of the brand's cult brightening treatment. Each drop layers glutathione, stabilised vitamin C and niacinamide into a lightweight watery serum that sinks in fast and gets to work on dark spots, post-blemish marks and lingering pigmentation traces.
Its 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, sharpens overall clarity and adds that fresh, lit-from-within glow that Numbuzin is loved for.
Two bottles mean months of consistent brightening or a smart way to share your favourite ampoule with a partner. A must-have for anyone building a serious K-beauty brightening routine around the No.5 line.
