As a senior woman with a history of oily and sensitive skin gly-sal pads are a necessity for me. I follow with a retinol moisturizing product and the combination works quickly to smooth the skin and clear clogged pore problems and blemishes. Over time milia and other skin bumps have also disappeared. This is a serious treatment product so I adjust use as needed (almost daily for me). The only 'con' is that of product evaporation. The inner lid does help so do not discard it.
