🧴✨ Isotretinoin 5mg Capsule: A Powerful Acne Fighter
Isotretinoin 5mg is a potent oral medication primarily prescribed for the treatment of severe, cystic, or nodular acne that does not respond to conventional therapies like antibiotics or topical treatments. It is a derivative of vitamin A (retinoid) and works by targeting the core causes of acne — excess oil production, clogged pores, inflammation, and bacterial growth.
🔬 Mechanism of Action
Isotretinoin acts on the sebaceous (oil) glands of the skin, shrinking them and significantly reducing sebum (oil) production. Less oil means fewer clogged pores and reduced chances for acne-causing bacteria (Cutibacterium acnes) to thrive.
Key effects include:
-
Decreasing sebum secretion
-
Promoting skin cell turnover
-
Reducing inflammation
-
Preventing formation of new acne lesions
-
Promoting healing of existing acne
This makes isotretinoin a comprehensive acne treatment addressing both symptoms and underlying causes.
