Isotretinoin is a derivative of vitamin A and belongs to a class of chemical compounds known as retinoids. It reduces the size of sebaceous glands and decreases sebum (skin oil) secretion, thereby reducing skin inflammation. As a result, it is used in the treatment of severe acne (cystic or nodular acne).
Acnotan® is formulated with isotretinoin using Liqui-Pep® liquid-filled capsule technology, which provides improved bioavailability, absorption, and therapeutic effectiveness.

One of the most common skin problems is acne, which occurs when skin pores become blocked with dead skin cells and sebum. Bacteria accumulate in these areas, leading to swelling, inflammation, redness, and the formation of pimples.
Isotretinoin, a derivative of vitamin A and part of the retinoid family, is used orally to treat severe acne in individuals who do not respond to conventional treatments. This medication reduces sebum production (a sticky, oily substance produced by sebaceous glands and located in the middle layers of the skin near hair follicles to maintain skin hydration and vitality) and decreases bacterial activity, thereby improving inflammation and acne.
