How It WorksIsotretinoin targets the root causes of severe acne simultaneously by:Shrinking sebaceous glands to dramatically reduce oil (sebum) production.Preventing clogged pores by normalizing how skin cells shed.Decreasing inflammation and limiting the growth of acne-causing bacteria.Preventing permanent physical scarring and deep tissue damage.
