Common questions

Does the Medicube Triple Collagen serum work?

As a hydrator, yes. Topical collagen holds water at the surface and makes skin feel plumper and smoother, which reads as firmer. It will not rebuild your own collagen, but for everyday hydration at this price it does its job well.

Which Medicube serum is best for brightening?

The TXA and Niacinamide 15% Glow serum is the active brightening pick, using tranexamic acid and a high niacinamide dose to target dullness and uneven tone. Pair it with daily sunscreen for the best results.

PDRN or Collagen: which should I choose?

Collagen leans toward hydration and a softer, firmer feel, while PDRN leans toward glow and barrier comfort. Pick by your top concern, or use one in the morning and the other at night, as they layer together without issue.
