Oily skin and redness do not leave a flawless first impression. Active Concepts developed a product that controls excess sebum and is the answer to this persistent problem. AC Sebum Control Enzyme PF comes from the Gallotannins and Ellagitannins of meadowsweet. Meadowsweet acts as natural astringents to reduce the activity of the sebaceous glands by inhibiting the activity of 5α-reductase. This in turn, limits the amount of sebum secreted due to an astringent effect by the tannins and can help prevent problem skin. AC Sebum Control Enzyme PF regulates sebum production and secretion so that we are not just covering up the problem but providing a solution!
