COMMON BRAND(S): Retin-A
GENERIC NAME(S): Trinon
OTHER NAME(S): Trinon Cream
This medication is used to treat acne. It may decrease the number and severity of acne pimples and promote quick healing of pimples that do develop. Trinon belongs to a class of medications called retinoids. It works by affecting the growth of skin cells.
I am always getting questions about Trinon and Retinol. What are they? How are they different? Do they really work for anti-aging? Today, I want to clear all of this up for you.
What is Trinon (Retn-A)? How does it work (mechanism of action)?
Trinon is a derivative of vitamin A. It is used on the skin (topically) in the treatment of mild to moderate acne and on skin that has been damaged by excessive exposure to the sun. Trinon irritates the skin and causes the cells of the skin to grow (divide) and die more rapidly, increasing the turnover of cells. The number of layers of cells in the skin actually is reduced. In patients with acne, new cells replace the cells of existing pimples, and the rapid turnover of cells prevents new pimples from forming. By a similar mechanism, Trinon can reduce some wrinkles, areas of darkened skin (hyperpigmentation), and rough areas of skin, all of which occur in sun-damaged skin.
In patients with sun-damaged skin, improvements in the skin usually are seen within the first 3 to 4 weeks of treatment. Brown spots begin to fade after six to eight weeks. Wrinkles decrease or disappear after three to six months. Following application to the skin, a minimal amount of drug is absorbed into the body.
The FDA approved topical Trinon in 1971.
Trinon, also known as all-trans retinoic acid (ATRA), is medication used for the treatment of acne and acute promyelocytic leukemia.
