Depilatory creams dissolve the hair at the surface of your skin. If used correctly, these creams are painless, so choose this method if you want to avoid the pain caused by waxing or epilators. Because the chemicals involved in this process are harsh, select a cream designed for delicate facial skin. Visit a beauty supply store, and search for a product that specifically states it’s for facial hair. If you’re unsure, ask  an associate to point one out for you. Apply a small dab to a sensitive but safe area (such as the skin of your inner wrist) to make sure your skin doesn’t react. Leave it on for the recommended amount of time, which will likely be around five minutes, and then wash it away thoroughly. Wait at least another 10 or 15 minutes to make sure your skin doesn’t begin to itch or turn red. Follow the instructions on the product carefully. They will likely tell you to let the cream sit on your skin for three to six minutes, but it’s better to err on the side of less time if it’s your first application. If you begin to feel a tingle on your upper lip, wipe the product away immediately. Lather your fingers with soap and water and then gently rub your upper lip to remove any of the product residue. Then rub or splash water on your upper lip to give it a final rinse. Depilatory creams are only a temporary solution, and the hair will grow back in three to five days. You can use the product again after three days, but stop using it if you get irritated, itchy, or red skin.
