Hello, I'm Dr. Loretta Ciraldo, Board Certified Dermatologist, and author of " Six Weeks to Sensational Skin." In this clip, we're going to talk about doxycycline acne medicine. Now, doxycycline is an antibiotic, which was first discovered to be very successful for the treatment of acne, many years ago, but the problem was, that when people took doxycycline for their acne, they could become very, very sensitive to the sun, so that just a little bit of sun exposure, could give them terrible blistering, and more or less, we stopped using doxycylcine for acne, but now there's very exciting new news about doxycycline, and that's that you can ask your dermatologist for a prescription for one of two drugs, that are low dose doxycycline, either periostat, which is taken twice a day, or the newer pill, oracea, which needs to be taken only once a day. Both of these pills are very low dose, and will not make you sensitive to the sun, and they're very effective for acne, and rosacea. This is Dr. Loretta Ciraldo, dermatologist, from Miami.
