Retin A, also often known as tretinoin, is produced from vitamin A and retinoic acid like the compound retinol, it too is also a part of the retinoid group- a group of vitamin A derivatives, and most times comes in cream or gel form. Its efficacy is touted throughout the dermatological community for treating bad skin as well as the scarring acne sometimes leaves behind. Not only that, if it just so happens you have old and wrinkled skin, you can use it to treat it as well, as it will make your skin look more youthful and vigorous.
As effective as tretinoin can be, its not without its problems. You may be liable to red and inflammed, or swollen skin if you tend to show a sensitivity to the treatment.
Skin discoloration may also occur in rare instances. Retin A also has the distinction of making the skin sensitive to sunlight, so a good sunscreen is usually prescribed to be used in tandem when undergoing this remedy.
