Overview
A drop-format facial serum from Korean skincare brand numbuzin, built around hyaluronic acid and niacinamide, sold in a 50 milliliter bottle with an aloe scent.
The pairing of hyaluronic acid for hydration and niacinamide for barrier support is a common combination in Korean serum formulas, and the listing also flags antioxidant properties. At 50 ml it is a larger serum bottle than many spot treatments, suited to regular daily use.
- 50 ml drop serum
- Hyaluronic acid and niacinamide
- Aloe scent
- Antioxidant formula
Who it's for
Fits anyone building a layered skincare routine who wants a hydrating, niacinamide serum before moisturizer, particularly fans of Korean skincare formats. Less suited to those who prefer fragrance free products, since this one carries an aloe scent rather than being unscented.
Pros and cons
- Hyaluronic acid and niacinamide combination
- Generous 50 ml size
- Antioxidant properties listed
- Aloe scent, not fragrance free
- Concentration of actives is not disclosed
Performance notes
Hyaluronic acid draws and holds water in the skin's surface layers, while niacinamide supports the skin barrier and, at sufficient concentration, can help even tone over time. The drop dispenser is meant to control dosing for a thin liquid layered under moisturizer.
