How does an IPL photofacial work? January 24, 2023 If you are planning on getting an IPL treatment in Houston, it is imperative that you avoid prolonged sun exposure, topical retinol/retinoic acid, and antibiotics for 2 weeks prior to treatment. This is a precaution that helps prevent sun burns and complications from treatment. Plus, you cannot receive treatment if you have a sunburn! Before your IPL Photofacial treatment begins, Dr. Downey or Dr. Bullocks will prepare your skin by thoroughly cleaning the desired treated area. This will ensure you will remain as comfortable as possible throughout the entirety of your treatment. Once numb, Dr. Downey or Dr. Bullocks will lay you down on one of our comfortable procedure tables and provide you with protective eyewear. They will then start applying bursts of intense pulsed light onto your desired treated area. While many patients are fairly comfortable throughout this procedure, most describe the feeling as being snapped with a rubber band. Each treatment session typically takes about 20 to 30 minutes to complete.
