What it's for (Indications)
- Topical tretinoin is primarily used to treat and reduce the severity of various types of acne and may also be used to reduce wrinkles.
- For acne, effects may be observed in 2-3 weeks, with full effects potentially taking up to 6 weeks.
- If no improvement is seen after 12 weeks, medical consultation is advised.
- (Note: Oral tretinoin capsules are indicated for the induction of remission in patients with acute promyelocytic leukemia (APL) characterized by the t(15;17) translocation or PML/RARα fusion.

Dosage Information
| Type | Guideline |
|---|---|
| Standard | For topical tretinoin, apply as prescribed by your doctor; frequency (e.g., nightly) depends on acne type and severity. The cream can be mixed with a moisturizer before application without decreasing effectiveness. Application instructions include washing hands, applying to the affected area, replacing the cap, and re-washing hands. (Note: For oral tretinoin capsules used in Acute Promyelocytic Leukemia (APL), the recommended dosage is 22.5 mg/m2 orally twice daily until complete remission. Treatment should be discontinued 30 days after achieving complete remission or after 90 days of treatment, whichever comes first. Discontinuation is also advised if the t(15;17) translocation or PML/RARα fusion is not identified.) |

How it Works (Mechanism of Action)
The exact mechanism of action of topical tretinoin in dermatological conditions like acne and wrinkles is not explicitly detailed in the provided data. (Note: For acute promyelocytic leukemia (APL), oral tretinoin induces cytodifferentiation and decreased proliferation of APL cells, leading to maturation of promyelocytes and repopulation by normal hematopoietic cells. The exact mechanism in APL is unknown.)
