Laser Hair Reduction

The Mediostar XT® has a long pulse duration allowing safe and effective hair reduction for most skin types, and a hand piece with greater cooling power to give patients the ultimate in comfort and efficiency.

THE MEDIOSTAR XT®

The Cooling Contact Device reduces pain and maximizes patient protection by delivering a constant cooling onto the top layers of the skin. Contact Cooling reduces the need for cooling gels and expensive anesthesia for most patients. Best of all, it helps decrease treatment time and allows for quick recovery. To understand how the Mediostar XT® works, it helps to know a little bit more about how hair grows and how laser light vaporizes unwanted tissue.

HOW DOES HAIR GROW?

Hair forms in a pouch-like structure below the skin called a hair follicle. What we perceive as hair is actually the hair shaft, which is the keratinized, hardened tissue that grows from this follicle. The best hair color for the laser light to target is brown or black. Our Health Care Provider will explain more during your consultation. Everyone’s hair grows differently, depending on age, weight, metabolism, hormones, ethnicity, medications, and other factors. But all hair goes through three distinct growth stages:

Active growth phase (called the anagen phase), which can last up to 3 months. At any given time, 20-30% of our body hair is in this phase. During anagen, the hair has an abundance of melanin and that is the key target for the laser light. To get the maximum result 6-8 treatments are generally required to achieve 90-95% permanent hair reduction, but more may be required.

Regressive phase (catagen phase), which lasts about 3 days, during which the hair stops growing, but is not yet shed. About 3 – 4% of our body hair is in this phase at any given time. Many patients report that hair starts to shed immediately, and can be found on a towel following a shower. We recommend not waxing, tweezing or using any methods to remove the hairs following your laser treatments.

Resting phase (telogen phase), which lasts 4-14 days, at the end of which the hair falls out and a new hair begins to form. Following the laser treatment the hair appears to still grow. These hairs are in fact club (dead) hairs and within 3-4 weeks the new hair from another active growth phase will begin to grow out of the same hair shaft. Remember that even though the hair is growing out of the same hair shaft, the follicle growing is new and is now ready for the laser light.

The light emitted by the Mediostar XT® is absorbed by the pigment (melanin) located in hair follicles, melanin pigments give hair its color, and hair shaft. The laser pulses for a fraction of a second, just long enough to vaporize the pigment in the hair follicle- disabling several hair follicles at a time to eliminate or significantly impede the hair’s regrowth – but not long enough to damage the surrounding skin. The Mediostar’s special contact-cooling hand piece further protects the epidermis (upper layer of skin). This patented method of epidermal preservation allows delivery of more laser energy deeper into the hair follicle.

While some areas of the body are more sensitive than others, most patients report little or no discomfort. For more sensitive patients, anesthetic creams can be applied prior to the treatment.

The number of sessions will vary for each individual. During the initial visit, the laser light disables those follicles in the “active” phase of the growth cycle. Follicles in the “dormant” phase will not be affected. Since follicles cycle through “active” and “dormant” phases, additional sessions may be desired once the “dormant” follicles become “active”.
