Thermage skin tightening treatment or The Youth Renew Marvel at Kaya addresses visible signs of aging and tones those trouble areas in just one treatment. Thermage uses patented radio frequency (RF) technology to safely heat the deeper layers of your skin, stimulating existing collagen and promoting new collagen growth for younger looking skin. No surgery - just naturally younger looking skin that can take years off your appearance. As you age, the collagen in your skin breaks down resulting in wrinkles and sagging skin. The results can last for years depending on your skin condition and natural aging process.
