Tretin-Iso 20 Capsule belongs to a class of drugs called retinoids (a synthetic form of vitamin A) primarily used to treat a severe form of acne known as nodular acne that cannot be cleared by any other treatments, including antibiotics. Nodular acne is severe acne that occurs due to excessive production of oil in the skin cells, causing swollen, red and tender lumps in the skin. Acne nodules are larger in size than typical pimples. 

Tretin-Iso 20 Capsule contains 'isotretinoin', a form of vitamin A that works by reducing sebum (skin's natural oil) production on the skin's surface by decreasing the activity and size of sebaceous glands. Thereby unblocks pores and kills acne-causing bacteria.

Nodular acne: It is severe acne that occurs due to excessive production of oil in the skin cells causing swollen, red and tender lumps in the skin which can be the size of pencil erasers or larger. The sebum inhibits sebaceous glands and stops oil from flowing out freely causing accumulation of sebum under the skin which increases the growth of acne-causing bacteria. Acne nodules are larger in size than typical pimples and affect the deeper layers of skin. Nodular acne can occur on the back, face and the body. If they are left untreated, it may cause permanent scars. The symptoms include long-lasting painful blemishes that feel like hard knots under the skin.
