Skin that is freshly tanned is still recovering from the inflammation of UV exposure, and there is a risk with Fraxel Dual Laser that you can create hyperpigmentation (dark spots). I'm sure you already know there are many reasons you don't want to tan - premature aging, skin cancer, and the increased risk of hyperpigmentation from everyday scrapes and bumps. If you are considering Fraxel Laser treatment, you'll want to avoid tanning both before the treatment, for safety and best results, and after the treatment, to protect your investment.In regards to Fraxel's safety and efficacy for skin that has a naturally tan or olive appearance, the answer is different. Fraxel is completely safe and effective for all skin tones, when administered by an experienced and skilled provider. In New York state it is especially important for patients to check their providers' credentials, as the laws are fairly lax about who can provide laser treatments. Make sure to do your research, and select a provider with specialized skill and experience in laser skin resurfacing.
