Yvette Armeni

Tell us about her:Yvette is a lymphatic drainage massage and cavitation specialist that will be available bi-monthly. Lipo Cavitation is a cosmetic procedure that is non invasive. It promises to eliminate localized fat from strategic parts of the body using ultrasound waves only targeting fat cells. This technique can be applied to various parts of the body such as, stomach, thighs, flanks, bra fat and back. When the fat cells melt, fatty acids and toxins travel through the lymphatic system then eliminate through urine. Results are instantly noticeable and felt. Patience can lose anywhere from 1/2 an inch to 2 inches of fat in just one session.

Lymphatic massage is done with a specific technique that helps filter the body's system and eliminates toxins which is incredibly important for immunity, circulation, optimal health, eliminates water retention and weight loss. Stress, sitting too much, lack of activity, injuries and poor posture also contributes to a sluggish lymphatic system.
