🧴💊✨ Isotretinoin 20mg Capsule: A Powerful Remedy for Severe Acne
Isotretinoin 20mg is a potent oral retinoid medication primarily used to treat severe, nodular, or cystic acne that hasn’t responded to other treatments like antibiotics or topical agents. It is a vitamin A derivative, originally developed for cancer treatment, but now widely recognized for its powerful anti-acne effects. Due to its strength and potential side effects, it is typically prescribed under strict medical supervision.
🧪 Mechanism of Action
Isotretinoin works by targeting all four causes of acne:
-
Reduces sebum (oil) production in the sebaceous glands.
-
Prevents clogged pores by normalizing keratinization.
-
Reduces bacterial growth (Cutibacterium acnes) by depriving bacteria of sebum.
-
Decreases inflammation within the skin.
These combined effects result in long-term remission of acne in many patients after just one treatment course.
