HOW LASER HAIR REMOVAL WORKS
While treating hair, the energy radiated by the powerful diode laser is utilized to prevent the regrowth of the hair. To do this, the light needs to enter a few millimeters into the skin to reach the base of the hair. When it meets the melanin in the hair (darker shading), the light is absorbed, i.e. it is changed over into heat. The darker, thicker and denser the hair, the more heat is created. This heat harms the cells in charge of hair regrowth inside the hair and in the region around the hair. This guarantees an extreme reduction in hair in the treated area.
In the meantime, it must be guaranteed that, regardless of the heat delivered, no blisters or scars develop. That is the reason the majority of Asclepion’s hair removal technologies incorporate a powerful skin-cooling component. This independently cools the most shallow layer of the skin quickly before the light pulse. It makes the treatment more comfortable for the patient.
CUTTING EDGE-LIGHT BASED TREATMENTS FOR PERMANENT HAIR REDUCTION
The High Power Diode Lasers of the MeDioStar NeXT Family, represent the best technology for permanent hair reduction treatments. The wavelengths of the MeDioStar NeXT devices were choosen so that the absorption of the light is high in melanin, yet low in water (essential substance in the skin). Therefore providing an exceptionally safe treatment, with generally few side effects. This makes it safe for all skin types (up to skin sort VI) with generally low risks of hypo-pigmentation or hyper-pigmentation.
Furthermore, an additional treatment mode (SmoothPulse) can be utilized for bigger regions. This influences the laser pulse sensation to be practically unnoticeable, even for sensitive skinned patients. Because of the advanced design of the MeDioStar NeXT lasers, side effects of no more than slight redness and swelling occur.
PAIN FREE, QUICK AND PERMANENT HAIR REMOVAL
There are 3 stages of hair cycles.
Anagen – Periods of growth.
Telogen – no growth
Catagen – transition between the two periods
Each hair is in a different phase of growth. During a hair removal session, all the hairs are targeted. There is no way of knowing in which phase of growth they are in. That means that, in a certain area, only a specific percentage of hair reacts to the laser treatment, i.e. only hairs in anagen phase. Therefore, a series of laser sessions is always necessary.
How many sessions are needed varies on a case by case basis. This will depends upon hair and skin type as well as on genetic predisposition. Normally, six to ten sessions per area are needed in order to reach hair reduction of up to 90%.
Since the laser beam targets the pigments contained in the hair, all pigmented hair will react very well to treatment. Hair from very dark to dark blond can be treated effectively, while white or grey hair will not respond to the treatment. In general, the darker the hair, the better the absorption and therefore the better the results.
The effectiveness of the treatment depends on the color, thickness and depth of the hair. The outcome of the treatment also depends on the hormone levels. To reach a high level of effectiveness, it is important to set up a treatment plan with your doctor based on your skin type and hair consistency.
The scientific literature shows that, 12 months following the end of treatment, the effects with latest generation lasers are very good. It can be microscopically proven that the hair follicles have definitely been damaged. Depending on genetics and hormonal changes follow up treatments can be necessary.
The hair should be shaved 12 hours before the treatment. After that, all dark spots on the skin (e.g. moles) are covered with a white pencil and a thin layer of transparent gel is applied to the skin. The laser handpiece of the laser is moved over the parts of the skin to be treated. The laser sends a light impulse, which creates a gentle prickling sensation. The treatment is very comfortable, thanks to the laser device’s skin-cooling system.
Following the treatment, a redness of the skin and a sensation of warmth can occur. Overall, the side effects are similar to a light sun burn and disappear a few hours after the treatment. The hairs fall out approximately after two weeks after the treatment.
The treatments are normally performed with an interval of three to six weeks.
