Isotretinoin capsules are used to treat severe acne that does not respond to conventional treatments such as topical or oral antibiotics. It works by reducing the size of the sebaceous glands in the skin, reducing the secretion of oils that contribute to clogged pores and the appearance of pimples and spots. The drug also helps reduce inflammation associated with acne and promotes skin cell renewal, which contributes to improving the appearance of the skin and reducing the formation of scars resulting from severe acne in cases where other treatments are ineffective.
Isotretinoin is one of the effective treatments for nodular acne and deep swellings that are difficult to treat with other methods. A doctor may prescribe it for acne that causes severe pain or affects the quality of daily life.
