This “Sheep Placenta Cell Collagen Anti-wrinkle Filling Cream” features a unique dual black technology of “active sheep placenta microcapsule + collagen fiber locking network” : It seals high-purity sheep placenta active cytokines in nano-lipid spheres, which burst upon touch and directly act on the skin’s base layer. Meanwhile, the three-dimensional collagen fiber network forms a breathable “invisible filling scaffold” in the sunken areas of wrinkles, immediately smoothing out visible lines and continuously stimulating the self-production of collagen.
