Tretinoin or Retinoin, or Retin-A, is an acid form of Vitamin A. It's used as a preliminary peel treatment to thin the outer layer of the epidermis, and thicken the layers below. Retin-A is a wonder drug for the complexion, and works in for various treatments.
In conjunction with chemical peels, it helps the peel penetrate evenly on top, while simultaneously stimulating collagen production in the deeper layers.
For pimples, Retin-A unplugs blackheads and whiteheads and it prevents oil build up and breakouts. You have to use it for about two months before you see the improvements, but it's worth it in the end.
For wrinkles, Retin-A acts as an exfoliate and gently softens your skins texture, while smoothing over fine lines. Retin-A will not erase deep lines, but they will be softened.
Retin-A can reverse the effects of hyperpigmentation from sun damage. Sun spots and freckles virtually disappear within a couple of months use.
Retin-A even helps treat hair loss, because of its' ability to help other medications penetrate the skin better. When it is used in conjunction with minoxidil, a follicle stimulator, hair starts growing more rapidly.
To get Retin-A you will need a prescription from a doctor and your insurance may or may not cover it. If not, a years worth of this wonderful cream will cost about $600 to $1000. You can also get some mild Retin-A on-line, from .025% tretinoin to 1%. drugstore.com. is a reputable and safe on-line company to buy from (I have bought from them). You will apply Retin-A at night, after cleansing and toning your skin. Follow with a moisturizer. During the daytime, it is very important that you wear sunscreen, because Retin-A makes skin extra sensitive to the sun and dryness. Some people break out when first using Retin-A, but usually after two weeks, the skin gets used to it and starts repairing itself.
