What is the primary use of isotretinoin in dermatology?

The primary use of isotretinoin in dermatology is for acne treatment. Isotretinoin, a powerful retinoid derived from vitamin A, is highly effective in managing severe forms of acne, particularly nodular acne, that have not responded to other treatments. It works by reducing the size and output of sebaceous (oil) glands, decreasing oil production, and preventing the clogging of hair follicles. Additionally, isotretinoin has anti-inflammatory properties and helps to normalize skin cell turnover, which further aids in reducing the formation of acne lesions.

While isotretinoin has some effects on skin texture and may indirectly contribute to improvements that can be perceived as anti-aging, its primary indication remains acne treatment. It is not used for moisturizing, skin lightening, or as an anti-aging solution in a primary context, making its use specifically targeted towards acne management.
