Retin-A is a medication used topically to treat acne and is available only by prescription. However, numerous products containing Retin-A are available for purchase at drugstores and grocery stores. The generic name of Retin-A is tretinoin.
There are numerous websites advertising the sale of Retin-A, but many of them are sources outside of the United States. Caution should be observed when buying any pharmaceuticals over the Internet or from any unverified sources, because they may not contain the correct ingredients or formulas. The best way to ensure that the product contains the correct dosage and solution is to obtain a prescription from a health care provider or purchase a solution containing tretinoin from a reputable store.
