The best procedure I have seen in my experience for acne and brown spots is the Spot Peel. There is very little downtime for this peel, just fine scaling starting 2 days after the peel and lasting for a few days, and you are sent home with a kit of medicated products including creams and a cleanser that will constitute your entire skin care regimen for a month afterward. The ingredients in this kit will continue to improve your skin over that month.
You should consult with a board certified dermatologist about the Ematrix Sublative Rejuvenation system. Ematrix uses bipolar radio frequency engery to heat below the surface of the skin, producing new collagen, creating smoother, tighter, younger appearing skin. Ematrix Sublative Rejuvenation System can be used safely and effectively on all skin types, and is the only effective technology to treat deep acne scarring in darker skin types.
