What is it?
Retin-A is used for the treatment of acne. It is sold by Ortho Pharmaceutical Company in the form of liquid, cream, or gel, and it contains tretinoin (retinoic acid and vitamin A). Retin-A is used topically on the portions of skin that are affected by acne. There is also some research that shows that it minimizes fine lines and may reverse some of the effects of sun damage.

Recommended Usage
It is recommended that Retin-A be used only once a day. Usage more often than this may cause redness, peeling, or discomfort and will not result in a better or more rapid outcome. In fact, using Retin-A too often may cause the skin to end up worse than it started.

Side Effects
Side effects may include heightened sensitivity to sunlight exposure on the areas of skin where Retin-A is used. In addition, some areas of skin may become red, blistered, or crusted. If any of these side effects are observed, treatment should be discontinued until the symptoms subside. Very few people have reported being allergic to the compound itself, but if you experience these symptoms, you should consult with your doctor to determine if you should continue treatment.

How does it work?
It is unknown exactly how Retin-A works, but it is thought that it may somehow loosen the connections between skin cells while at the same time stimulating the growth of new cells. This, in turn, helps to expel blackheads. The skin will be loosened, allowing dirt to be washed away. Older cells that were partly the cause of acne will be sloughed off and new cells will take their place.

The vertebrate retina is a light-sensitive tissue lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centers of the brain through the fibers of the optic nerve.
