Retin-A is a brand name for tretinoin, which is a retinol cream containing retinoic acid (vitamin A acid). Retin-A lightens the skin and causes cellular turnover, replacing old skin with newer skin. This product is approved by the Food and Drug Agency (FDA) and available only by prescription. The effects of Retin-A range from clearing acne to reducing the appearance of fine lines to lightening spots on the skin.
Acne Treatment
Retin-A is used to treat mild acne. It reduces the number of pimples that form on the skin and helps heal the ones that do develop. Whiteheads and blackheads can be treated with a topical treatment of Retin-A. It opens the pores and keeps them from getting clogged, according to the American Academy of Dermatology. Retin-A is available only by prescription from a doctor. It comes in gel, solution, liquid or cream form and is applied topically.
Wrinkle Reduction
Dermatologists prescribe Retin-A for treating fine lines and wrinkles. The effects of Retin-A applied to the skin are improved appearance of fine wrinkles, increased collagen production and repair of photo-aged skin.
Skin Lightener
Another effect of using topical Retin-A is the lightening effect it has on the skin. This is a good treatment for brown spots on the surface of the skin. Retin-A lightens accumulations of pigment in the skin and, when used with a mild skin-bleaching agent, evens the skin color.
Sun Sensitivity
Retin-A causes sun sensitivity in the skin. It is important to use a sunblock of SPF30 (UVA and UVB) to protect the skin while using the product. Do not use sun lamps, tanning booths or spend time in the sun without protection from the harsh rays of the sun.
Skin Irritations
Retin-A causes redness or a flush of the skin in some individuals. In extreme cases, the skin may become extremely red, swollen or have blisters. These may be temporary and go away after the skin adjusts to the treatment. If any excess skin irritation persists, stop using the product and consult a doctor.
Skin flaking is another common effect of using Retin-A, but this is temporary, and the skin returns to normal after it adjusts to the treatment. For this reason, you should stay away from harsh cleansers and abrasive soaps while using Retin-A.
Precautions
Retin-A can cause birth defects. Pregnant women or women who may become pregnant should not use this cream. In addition, women who are nursing should not use this product, as it is not known if the drug is passed in the milk, according to the National Institutes on Health.
There is a possible interaction with preparations containing sulfur, resorcinol or salicylic acid. Do not use these products while using Retin-A.
