A derivative of Vitamin A, Adapalene gel 0.1% is a member of the retinoid ingredient family and previously only available by prescription. Retinoid help slow down the accumulation of dead skin cells in the pores, which is a main contributor to breakouts. Retinoid also help prevent and improve white heads and blackheads because they increase cell turnover. Studies have shown that compared to other retinoid, Adapalene gel 0.1% causes less irritation to the skin. Adapalene gel is oil-free, fragrance-free and dermatologist developed.
