We offer seven different skin-enhancing facial treatments, every one of them fights ageing and visibly improves your skin. They include: microdermabrasion, a peeling with microcrystals; cryotherapy, in which cryogenically cooled air is used; oxygen therapy, in which oxygen is used; and mesotherapy, in which radiofrequency is used. Our two final treatments each combine two of the above therapies for optimal results!
