Scalp – Alopecia. Hair loss is gradually stopped and regrowth is stimulated. LED sessions, performed during the month following a hair transplant, lead to faster regrowth of the grafts. In combination with hair mesotherapy, the LED lamp effectively treats diffuse alopecia in both men and women. The action of yellow and red light at the end of the treatment stimulates cell renewal. In just a few sessions, Médisol LED treatment significantly slows hair loss and results in increased hair density and regrowth. Acne. Blue LEDs act on and destroy the proteins of the bacteria responsible for acne (porphyrins). Red LEDs penetrate deeply to reach the sebaceous glands for an anti-inflammatory effect. Acne scars and marks are also reduced. But that's not all: we now know that LED therapy also detoxifies the body and boosts immunity. How does an LED session work? Comfortably lying down, panels equipped with diodes are precisely positioned a few centimeters from the areas to be treated. The light, emitted for fifteen to thirty minutes, provides absolute relaxation: don't be surprised if you doze off! This relaxing effect is due to the positive action of LEDs on the secretion of serotonin, more commonly known as the "feel-good hormone." The advantages of LED therapy: no risk of burns or pigment rebound; no side effects; suitable for all skin types; no downtime; an effective, gentle, and "natural" rejuvenation technique; risk-free (it's not UV!). How often should LED sessions be performed? For your light therapy, the protocol varies according to your needs and indications. Indeed, more LED therapy sessions may be required depending on the severity of the problem and the condition of your skin. When used alone, the recommended sessions are generally one to two per week for two months. Afterward, we recommend a maintenance phase with one session per month. In all cases, a personalized protocol is established beforehand with your doctor and may therefore vary from one patient to another.
