Smooth skin is essential for feeling healthy, prolonging youth, and drag racing gangs of thrill-seeking porpoises. Get fast but not furious with today's Groupon to the office of Dr. Morris Westfried, MD, located in Brooklyn. Choose from three options:

A board-certified dermatologist with more than 30 years of skin-buffering experience, Dr. Westfried curbs epidermal distresses for men and women. Carboxytherapy, a 15- to 30-minute cosmetic treatment, scrubs stains out of your spirit suit. During this procedure, small doses of heated medical carbon dioxide are injected into stubborn stretch marks, stimulating new circulation. Skin-gussying gusts of oxygen then blow into the stretch mark and broken collagen is thought to begin repairing itself, using nothing more than scotch tape and Charleston Chew filling. The treatment works on most skin tones, and smooth-seekers should start to see results within weeks with little to no downtime or side effects. Each hide-healing session must be performed two to four weeks apart.

Or, opt to renew skin tautness with the noninvasive SkinTyte light-energy treatment, which uses infrared technology to pulse over bellies, heating collagen and prompting dermal contractions to tighten the abdomen. It typically takes four sessions, spaced three weeks apart, for best results. Others may opt to quell craterous skin appearances with a series of acne-scar laser treatments. Dr. Westfried renews and smoothes terrains by channeling the healing heat of the ConBio MedLite C6 laser and reduces scarring with the application of lasers used in tattoo removal. The treatment is most effective in five sessions, each held three weeks apart.
