absorbed by the melanin within the hair and heat is generated. The heat then conducts out towards the germ cells. As long as a sufficient temperature is maintained for the required time then these cells will be successfully destroyed. This is absolutely critical – attaining the required temperature is not sufficient unless it is kept at that temperature for the corresponding time. This is determined by the Arrhenius Rate Equation. To achieve these conditions the laser/IPL system must be able to generate the required power output. The main reason why hair removal fails is simply because the equipment cannot generate the desired temperature for the correct time.
122: 43: 180:. IPL systems typically output wavelengths between 400 nm and 1200 nm. Filters are applied to block shorter wavelengths, thereby only using the longer, "redder" wavelengths. IPLs offer certain advantages over laser, principally in the pulse duration. While lasers may output trains of short pulses to simulate a longer pulse, IPL systems can generate pulse widths up to 250 ms, which is useful for larger diameter targets. Some current IPL systems have proven to be more successful in the removal of hair and blood vessels than many lasers. 162:(IPL), and both alexandrite and diode lasers. The review found no statistical difference in short-term effectiveness, but a higher incidence of side effects with diode laser-based treatment. Hair reduction after six months was reported as 68.75% for alexandrite lasers, 71.71% for diode lasers, and 66.96% for IPL. Side effects were reported as 9.5% for alexandrite lasers, 28.9% for diode lasers, and 15.3% for IPL. All side effects were found to be temporary and even pigmentation changes returned to normal within six months. 4302: 2682: 137:(FDA). Under the FDA's definition, "permanent" hair reduction is the long-term, stable reduction in the number of hairs regrowing after a treatment regime. Many patients experience complete regrowth of hair on their treated areas in the years following their last treatment. This means that although laser treatments with these devices will permanently reduce the total number of body hairs, they will not result in a permanent removal of all hair. 285: 533: 634:
cause serious harm, and even death. Typically, the cream is applied about 30 minutes before the procedure. Icing the area after the treatment helps relieve the side effects faster. Ibrahimi and Kilmer reported a study of a novel device of diode handpiece with a large spot size which used vacuum-assisted suction to reduce the level of pain associated with laser treatment.

technique. But the treatment is slow and tedious compared with typical newer laser hair removal. More hair may grow in certain areas that are prone to hormone-induced growth (e.g. a woman's chin and neck) based on individual hormone levels or changes therein, and one's genetic predisposition to grow new hair.

Typically the shedding of the treated hairs takes about two to three weeks. These hairs should be allowed to fall out on their own and should not be manipulated by the patient for certain reasons, chiefly to avoid infections. Pulling hairs after a session can be more painful as well as counteract the

Some level of pain should also be expected during treatments. Numbing creams are available at most clinics, sometimes for an additional cost. Some numbing creams are available over the counter. Use of strong numbing creams over large skin areas being treated at one time must be avoided, since it can

Spot size, or the width of the laser beam, directly affects the depth of penetration of the light energy due to scattering effects in the dermal layer. Larger beam diameters or those devices that has a linear scanning results in deeper deposition of energy and hence can induce higher temperatures in

Some normal side effects may occur after laser hair removal treatments, including itching, pink skin, redness, and swelling around the treatment area or swelling of the follicles (follicular edema). These side effects rarely last more than two or three days. The two most common serious side effects

Multiple treatments depending on the type of hair and skin color have been shown to provide long-term reduction of hair. Most people need a minimum of eight treatments. Current parameters differ from device to device but manufacturers and clinicians generally recommend waiting from three to eight

In essence, the important output parameter when treating hair (and other skin conditions) is power density – this is a combination of energy, spot diameter and pulse duration. These three parameters determine what actually happens when the light energy is absorbed by the tissue chromophore be it

Pulse width (or duration) is one of the most important considerations. The length of the heating pulse relates directly to the damage achieved in the follicle. When attempting to destroy hair follicles the main target is the germ cells which live on the surface of the hair shaft. Light energy is

As waxing has evolved, there are two types of waxing. In one, the strips are already ready to use, and one can apply it to the skin and peel it off in the direction opposite to the hair growth. Another one involves heating up the wax, applying it to the skin, and then placing a cloth on it and
