Laser hair removal is a permanent hair reduction solution that targets pigment in hair follicles to produce lasting results. Multiple sessions and visits to clinics may be needed before seeing lasting results.
Selecting an effective laser can make or break your success rate with this procedure. An incorrect laser could target skin tone instead of hair and burn your skin causing significant harm.
Alexandrite
Laser hair removal treatments use timed pulses of energy-filled laser beams that pass over the skin to convert light energy to heat energy that destroys unwanted hair follicles, thus preventing future hair regrowth and leaving areas looking smooth, even, and natural. It’s a safe and effective method of permanently eliminating unwanted hair from virtually any part of the body; faster than electrolysis; it treats multiple hairs per pulse; also much more comfortable compared to inserting needles directly into hair follicles!
The alexandrite laser’s wavelength of 755nm is well suited for treating lighter skin tones of Tone 1, 2, and 3. This is because its light doesn’t absorb melanin, the substance responsible for giving darker skin its pigmentation. While blonde hair contains insufficient melanin to be effectively removed using traditional Laser Hair Removal machines, its removal can still be achieved using specially developed machines using longer wavelengths like 1064 nm Nd:YAG laser.
Some studies have demonstrated that per-laser-pulse comparisons show the LightSheer (diode) laser to be more painful than its GentleLASE (Alexandrite) counterpart; however, overall their effects were similar; diode lasers used in these studies had longer wavelengths which enabled deeper penetration without damaging surface layers of skin.
Dependent upon the density and color of your hair, up to eight laser treatments may be necessary for you. Each session is extremely comfortable; therefore, you can return directly to work or other activities following each session.
Hyperpigmentation, hypopigmentation and erythema are some of the more frequently reported side effects of laser hair removal treatments. These reactions typically appear several weeks post treatment due to melanin pigment being altered by laser. Sun exposure should be limited and sunscreen used during treatments; in addition, no shaving, plucking, waxing or depilatory cream use should occur 12 days prior to each laser appointment and three or four weeks before visiting tanning or solarium facilities for treatments.
Diode
Laser hair removal uses advanced technology to permanently disable unwanted hair follicles. During treatment, pulses of light from a handheld device penetrate deep into your skin to target pigment in hair follicles that produce hair growth. Light energy converted to heat destroys these follicles and stops further hair production; all without anesthesia or incisions needed – you can return to regular activities right away!
Diode laser hair removal treatments can benefit anyone suffering from unwanted hair. However, diode lasers are particularly helpful for people with fine and light locks as other laser types, like Alexandrite and Nd:YAG lasers may accidentally target skin instead of hair and cause burns; unlike these other options, however, diode lasers can precisely distinguish between skin and hair and deliver safe yet effective treatment.
Diode lasers offer more than just hair removal; they’re also effective against redness, vascular lesions and hyperpigmentation as well as improving skin tone and texture with collagen production stimulation. A great alternative to waxing or shaving!
Diode sessions vary in duration depending on your aesthetic goals and treatment area size; some patients with multiple large areas to treat may require up to an hour-long appointment while those treating only one small spot may finish in just 20 minutes.
Before your laser session, it’s essential that you follow all instructions given by your physician or technician, including avoiding sun exposure and using SPF sunscreen on the day of treatment. Furthermore, conducting a patch test first on small areas of skin could ensure it’s suitable for you and avoid unpleasant surprises during a session.
Diode laser hair removal technology is great because it can be applied to virtually every part of the body where unwanted hair grows, including arms, legs, face and bikini line. Furthermore, diode can effectively target melanin in darker hair to destroy its follicle without harming surrounding skin cells or damaging nearby hair follicles.
Nd:YAG
Laser hair removal has become one of the most sought-after cosmetic treatments, and with good reason: it is safe, fast and effective at eliminating unwanted body hair. But not all lasers suit every skin type or concern – which is why choosing the Nd:YAG laser could be especially useful for dark skin to treat both hair removal and discoloration issues.
The Nd:YAG laser utilizes a powerful beam of light to target pigment and destroy hair follicles, while its long wavelength allows it to safely penetrate deep into skin without harming surrounding tissues – an advantage when treating dark skin since other lasers may cause hyperpigmentation in this area.
Nd:YAG lasers can also help eliminate acne and discolorations with its light beam, penetrating skin to break apart melanin pigment that causes brown spots before targeting blood vessels that supply hair follicles which eventually leads to their demise and the disappearance of spots altogether.
ND:YAG lasers are widely utilized to reduce the appearance of fine lines and wrinkles. Their deep penetration into the skin helps stimulate collagen production and support firmness while their pulsing action allows targeted damage to be caused to its surface, diminishing fine lines and wrinkles over time.
Recent research demonstrates that long-pulsed 1064-nm Nd:YAG laser treatments were safe and effective at hair reduction for patients with darker skin tones. Furthermore, shorter pulse treatments proved equally successful than longer ones.
Ruby
The ruby laser emits a red-colored beam that targets melanin in hair shafts and adjoining skin cells, and builds heat there, disabling new growth from occurring and eventually leading to its fall off over the course of several weeks. You may help expedite the shedding process by gently scrubbing with cloth or sponge. While this laser treatment is best suited for light to medium hair and fair skin tones, long-term results might require other approaches.
Laser hair removal works on the theory of selective photothermolysis, in which laser light destroys targeted structures (chromophores) without harming any unintended tissues nearby. For maximum effectiveness, exposure time (pulse duration) must be shorter or equal to thermal relaxation time of target structure – the time required for it to cool and cause thermal injury to the target structure.
One of the first lasers used for laser-assisted hair removal was the ruby laser, which is effective at dismantling pigmented follicles in Fitzpatrick skin types I to III but can lead to epidermal side effects in darker skin colors due to its targeted operation mode which targets all melanin spectrum including epidermal melanin content – particularly noticeable among patients who belong to Fitzpatrick skin types IV to VI due to high epidermal melanin content.
This issue was solved through the adoption of longer wavelengths. These wavelengths are less selective towards epidermal melanin and penetrate deeper, decreasing risk for untargeted tissues and providing improved hair removal results over shorter wavelengths. Additionally, longer wavelengths provide superior hair removal effectiveness than their shorter counterparts.
The Alexandrite laser uses a long wavelength system to deliver pulses of energy directly into its target area, making this treatment quick, effective, and comfortable for most people. Furthermore, its safe for light to olive skin tones as well as larger body areas – making it an excellent option. However, those with tanned or dark skin tones may find this uncomfortable; plus it may not be as effective against very dark tones.
