Ferment-rich ampoule for tretinoin recovery, hydration, and calmer barrier days.
What the community says
Redditors use this unflashy ferment ampoule for hydration and barrier support, especially alongside tretinoin or during cold-weather dryness. They report softer, calmer skin and better resilience, though ferment-sensitive users report irritation and some question whether it does enough.

What the science says
Niacinamide has some evidence for acne, as most studies found it helped and often matched clindamycin applied to the skin 1. It also has some evidence for dark spots, with all four direct studies showing fading and better results than a moisturizer without it 2. Two studies found it has some evidence for signs of aging, improving firmness and reducing wrinkles 3. For the skin barrier, the evidence is thin: one study found less water loss and a thicker outer layer, so this is not proven yet 4.
