Your skin is like any other part of your body. It needs to be preconditioned and maintained in order to optimize its health over a long period of time. If you have not taken care of your skin, you're probably right, it is not going to react well initially, which is why we always recommend you to precondition your skin to get it optimized, and in as good as shape as possible prior to any laser treatment. The laser treatment is really the final step in improving your skin, and the beauty of laser technology today is that it is able to address multiple issues in your skin. Namely it can address: pigmentation, vessel hyperactivity or rosacea, acne scarring or any post surgical scarring, large pores, texture abnormality, any kind of fine lines or aging atrophy of your skin. It is most important to have the right kind of laser for the right type of skin, and the right type of patient, which is why I recommend you find the right practitioner with the right experience who can diagnose your skin condition and know how to treat it properly. At our practice we use a number of of different technologies, because we want to treat the many diverse problems in the diverse patients we see in the New York metro area.
