What is Tretinoin?
Tretinoin is a derivative of vitamin A, known as a retinoid. It is a common ingredient in prescription-strength acne treatments.
In addition to fighting acne, it may also help improve fine lines and dark spots resulting from sun damage.

Benefits:
Tretinoin may provide the following benefits:
reducing the appearance of fine lines and dark spots
improving skin texture
reducing the frequency and severity of acne outbreaks
clearing up existing acne
Retinoids, such as tretinoin, stimulate the generation of skin cells, meaning they grow and divide quicker. This accelerates the removal of dead skin cells and keeps the pores clear of bacteria and other irritants.

Uses:
Tretinoin is used to treat acne or other skin diseases as determined by your doctor. It works partly by keeping skin pores clear. One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by the damaging rays of the sun.
Side effects:
Despite its effectiveness, tretinoin can have side effects, such as:
red, dry, or peeling skin
burning or itching near the application site
skin that feels warm to the touch
lightening of the skin at the application site
Tretinoin and other retinoids can also thin the skin's outer layer, leaving it more vulnerable to sun damage.
Healthcare professionals recommend people using retinoids wear sunscreen whenever they go outside.
