If your skin’s been looking tired, feeling dry, or losing its natural firmness, the No. 4 Numbuzin serum with 73% collagen might be your next obsession. Designed to deeply hydrate, visibly smooth out wrinkles, and bring back that springy, youthful bounce—this is not your average anti-aging step. With its lightweight, pudding-like texture, it melts into the skin instantly—cooling, refreshing, and delivering hydration that lasts. If you’ve been chasing firm skin, but everything feels too heavy or too greasy, this serum gives you that sweet spot: light, silky, and seriously effective.
How It Works: Hydrate, Lift, Restore
At the heart of this Numbuzin serum is a high concentration of collagen for skin—sourced from a blend of two collagen types that work together to replenish what your skin naturally loses over time. Add in hydrolyzed elastin and eight kinds of hyaluronic acid, and you’ve got a formula that doesn’t just sit on the surface—it sinks in and works deep. With regular use, it helps lift tired areas, reduce fine lines, and improve elasticity—giving your skin that bouncy, firm feel that so many products promise but few deliver. Whether you’re dealing with early signs of aging or dryness that exaggerates texture, this serum brings the skin back to life.
