Want a facelift without the surgery? Enter: radiofrequency!
Read the entire article
If you want smoother skin, smaller pores, or a brighter complexion, our rejuvenating radiofrequency facial is for you!
The treatment begins with a deep cleansing of the face and neck using a cleansing milk, a cleansing lotion, and gommage. This gentle yet effective exfoliant is applied to clean skin, left to dry, and then rubbed off with the fingertips. As the product dries on the skin, it absorbs impurities and dead skin cells, which are then wiped away.
Next, your skin is massaged with a soft-nozzled device that emits a radiofrequency signal. These energy waves heat the dermis and epidermis, boosting the production of collagen and elastin – the secrets to firm, radiant skin. They also improve your connective tissue, stimulate lymphatic drainage, and help the active ingredients in the products penetrate deeper into the skin.
The treatment ends with a massage and a hydrating gel mask. Your skin may be slightly red and feel warm to the touch immediately after treatment, but this disappears quickly. The results are immediate and continue for about two to three months.
Our Beauty Clinic uses radiofrequency as part of its mesotherapy , micromesotherapy , and cryomesotherapy treatment. If you're not sure which treatment to choose, book a free consultation with our certified beauty expert, who is happy to explain the treatment options to you, listen to your needs, and give you advice.
