Thermage FLX is a 2 hour non-invasive treatment that works by using radio frequency technology to heat the deep layers of your skin, helping to remodel existing collagen and produce new collagen, combating loose and sagging skin caused by age, weight loss, birth and other determining factors. By heating the deep layers of the skin, Thermage causes collagen fibres to contract, instantly giving you a smoother, firmer and younger look. The results last 6 - 9 months and can be seen in a single treatment with no down time.
