It is also useful as maintenance therapy for people who have responded to their initial treatment, reducing the prolonged use of antibiotics for acne. Leukemia
Tretinoin is used to induce remission in people with acute promyelocytic leukemia who have a mutation (the t(15;17) translocation 160 and/or the presence of the PML/RARα gene) and who do not respond to anthracyclines or cannot take that class of drug. It is not used for maintenance therapy.The evidence is very uncertain about the effect of tretinoin in addition to chemotherapy for patients with an acute myeloid leukemia on diarrhoea, nausea/vomiting and heart-related toxicity grades III/IV. Furthermore, tretinoin in addition to chemotherapy probably results in little to no difference in the mortality, relapse, progress, mortality during the trial and infections grade III/IV. Photoaging
Photoaging is premature skin aging resulting from prolonged and repeated exposure to solar radiation. Features of photoaging include fine and coarse wrinkles, change in skin pigmentation, and loss of elasticity. In human skin, topical retinoids increase collagen production, induce epidermal hyperplasia, and decrease keratinocyte and melanocyte atypia. Topical tretinoin is the most extensively investigated retinoid therapy for photoaging. Topical tretinoin can be used for mild to severe photoaging in people of all skin types. Several weeks or months of use are typically required before improvement is appreciated. The benefits of topical tretinoin are lost upon discontinuation. Although it has only been studied for a duration of two years, it may be continued indefinitely.
Research
Tretinoin has been explored as a treatment for hair loss, potentially as a way to increase the ability of minoxidil to penetrate the scalp, but the evidence is weak and contradictory.It has been used off-label to treat and reduce the appearance of stretch marks. It has also been studied in skin aging. References
