Application:
Isotretinoin is used to treat severe cystic acne (also known as nodular acne) that has not responded to other treatment (e.g., benzoyl peroxide or clindamycin applied to the skin or tetracycline or minocycline taken by mouth).
Isotretinoin is primarily used as a treatment for severe acne. The most common adverse effects are a transient worsening of acne (lasting 2-3 weeks), dry lips (cheilitis), dry and fragile skin, and an increased susceptibility to sunburn.
As the retinoid, there are strong and fast proliferation inhibition and differentiation of skin gland cell function, effective on severe nodular cystic acne. The gastrointestinal absorption is better, while the local medication invalid. Other drugs used to treat invalid serious acne, cystic acne, acne conglobata, rosacea, ichthyosis, keratosis follicularis and pityriasis rubra pilaris and other skin diseases also have a certain effect.
For severe acne. Anti skin dyskeratosis medicine. For the treatment of severe acne and other disorders
