Biodance Pore Tightening Collagen Ampoule is a premium ampoule for enlarged pores and lost collagen. As collagen is lost with age, the pores start to enlarge and sag, leading to wrinkles and poor elasticity. Featuring 74% ultra-low molecular weight 243DA collagen, the particles are small enough to actually enter the pores for an immediate boost in skin collagen content. Studies show 168% immediate increase in collagen, 15.6% reduced pore size, 33.5% reduced pore volume, 14% reduced pore depth and 18% reduced pore quantity. The formula sticks to the pores but leaves the skin feeling firm and non-greasy. Makeup application and lasting power will also be boosted.
