What is the Difference Between Isotretinoin and Tretinoin?

Isotretinoin and tretinoin are both prescription medications used to treat acne, but they differ in their severity and side effects. Here are the main differences between the two:

1. Form: Tretinoin is a topical medication that comes as a cream or gel, while isotretinoin is an oral medication.
2. Strength: Isotretinoin is more potent than tretinoin and is typically used to treat severe acne that has not responded to other treatments.
3. Side Effects: Tretinoin has fewer side effects compared to isotretinoin, which has a larger and more serious range of potential side effects. The most common side effects of tretinoin are mild skin irritation and skin peeling due to faster cell turnover.
4. Treatment Duration: Isotretinoin is often prescribed for a limited period, usually around 4 to 5 months, while tretinoin may be used for longer periods to maintain acne control.

Before deciding on isotretinoin over tretinoin, or vice versa, it is essential to consult with a healthcare professional to determine the most suitable treatment for your specific acne condition.
