Tretinoin
Uses of Tretinoin
Tretinoin has topical and oral formulations with different uses. Topical tretinoin is a retinoid used for acne and selected sun-damaged skin changes, while oral tretinoin is used under specialist care for acute promyelocytic leukaemia.
Tretinoin is commonly used for:
- Acne vulgaris: Topical formulations reduce comedones and help prevent new acne lesions.
- Photoaged skin: Selected topical products can improve fine wrinkles and roughness caused by long-term sun exposure.
- Acute promyelocytic leukaemia: Oral tretinoin promotes maturation of abnormal blood cells as part of specialist cancer treatment.
The formulation must be confirmed because topical and oral products are not interchangeable.

How Tretinoin works
- Tretinoin is a derivative of vitamin A belonging to the retinoid class of medicines.
- It works at the cellular level by binding to specific nuclear retinoic acid receptors in skin cells. This stimulates skin cell turnover, accelerating the shedding of old, dead surface skin cells and promoting the growth of new cells.
- By unclogging pores and preventing sebum buildup, Tretinoin reduces acne formation. Additionally, it stimulates new collagen production in the deeper layers of the skin, improving skin firmness, elasticity, and texture.
