Silab research offers p-Refinyl, a multi-action active ingredient which attenuates the unsightly appearance of dilated pores and reduces sebum production.

It limits pore distortion and slackening by reinforcing the collagen structure of the dermis. By tightening the pores, p-Refinyl smoothes the skin grain and limits shininess. ...
