Niacinamide and hexapeptide-9: depends on the strength

Depends on the strength

Use them together in the same routine, applying niacinamide first and hexapeptide-9 right after, because they boost each other's skin benefits. Niacinamide helps your skin absorb the peptide better while strengthening your moisture barrier, leading to smoother, younger-looking skin. You can use them both daily without changes, or space them out if your skin feels sensitive.
