Tretiva 40mg, which contains Isotretinoin 40 mg, is a powerful treatment for severe acne. It works primarily by shrinking sebaceous glands, which reduces the production of sebum, a key factor in acne formation. Less sebum means fewer clogged pores, leading to fewer acne lesions.

Additionally, Tretiva has anti-inflammatory properties that help to reduce the redness and swelling associated with severe acne. It also minimizes the growth of acne-causing bacteria, further aiding in acne control.

Due to its potent effects, Tretiva is usually prescribed when other treatments have failed. It is crucial to follow the prescribed dosage and duration to manage potential side effects and achieve optimal results.
