Abstract

A laser rejuvenation depending on the wavelength can treat wrinkles, dilated pores, dry skin, brown spots, sagging, vascular lesions, and texture but sometimes we need to make many sessions to see a clear benefit before and after or we have a very long recovery time. By applying different cosmetics after a resurfacing, we can achieve quicklier results with an integral rapprochement. The purpose of this study is to use a non-focused which creates acoustic pressure above the skin for trans-epidermal delivery of cosmeceutical products to prove better and quicker results after one laser treatment. A random sampling of 60 people was divided into 6 groups to try different products and they were evaluated with a computer skin analysis, pictures before and after, an ultrasound, a satisfaction survey, and biopsies before the procedure and one month later. The rejuvenation agents used in the present study were retinoic acid, vitamin C, hydroquinone, hyaluronic acid, tranexamic acid and a combination of these cosmeceuticals.
