Gentle yag

        A laser developed by Candela, USA, is gentle and extremely effective in hair removal for all skin types. Moreover, it can be used for treating any vascular disorders not bigger than 2.5 mm in both face and legs and reducing wrinkles. Operated by professional physician, a high resolution cooling technology combining with laser which has precise energy and emit time causes the most satisfying result.



         Gentle Yag is a long pulse Nd (YAG laser) with 1064 nm wavelength and 80 J of energy. It can deeply go down the skin and very specific to skin pigment around hair follicle. Therefore, it can eliminate black and brown hair in all skin types. Moreover, it is well absorbed by red blood cells, so it can be used for treating blue-black varicose veins which have either small or large size as well as stimulating skin collagen without dark spots on treatment area. While laser is working, DCD (Dynamic Cooling Device), copyrighted by Candella, will cool down your upper skin layer before every laser shot. This causes upper skin layer protection and any red or black spot will not be occurred after treatment. In addition, Gentle Yag causes no wound, and patients can do their normal activities.

Depending on size of lesions, the tip sizes are as follows:
Varicose veins on face and legs: 1.5, 3 mm
Wrinkle reduction: 6, 8, 10 mm
Hair removal: 12, 15, 18 mm
