Product details

A silver and yellow No.5 Glutathione TXA Ampoule Concentrate vial on a butter-yellow backdrop between white glutathione powder and a sprig of sea buckthorn berries

2-week dark spot ampoule

Pure glutathione powder and a tranexamic acid ampoule, mixed fresh at first use for targeted dark spot care.

Numbuzin’s No.5 Ampoule is the intensive partner to its daily No.5+ serum. The cap holds pure glutathione powder; press it and it drops into a vitamin ampoule of sea buckthorn water, tranexamic acid and more glutathione, so the actives stay fresh until the day you start. One bottle is a two-week course for dull tone and stubborn dark spots.

Good to know

  • Use within two weeks of mixing, and store it away from direct sunlight to keep it from oxidizing.
  • Glutathione has a strong, pungent smell; Numbuzin says that’s normal.
  • Skin irritation tested, but Numbuzin suggests mixing it with your other products at first and patch testing if your skin is sensitive. Once skin adapts, use it on its own.
  • Brightening care: wear sunscreen during the day while you use it.
  • For stubborn spots, Numbuzin suggests layering it over the No.5+ Glutathione Vitamin Concentrated Serum.
  • Sold as a single 10.7 g vial.
