Early laser hair-removal devices did not perform optimally on dark skin because the pigment in the epidermis interfered with follicular destruction. More recent devices, like long pulse neodymium-yttrium aluminum-garnet (Nd:Yag) lasers, circumvent this issue by passing over surface melanin without interfering with its destruction.
Prior to scheduling a treatment session, inquire with your practitioner as to their experience treating patients with dark skin and look for machines with two wavelengths.
Heats the Follicle Slightly
Laser machines emit energy in the form of light and heat that targets hair follicles with laser light and heat energy, damaging them without harming surrounding skin. Each laser’s wavelength determines how deeply its heat and light penetrates into skin layers and the type of follicle it targets – Pale/Medium skin is best treated using Alexandrite (755nm), while darker skin should opt for Nd:YAG (1064nm).
At first, laser hair removal on dark skin was difficult because its longer wavelengths were absorbed by melanin in the skin – an absorption chromophore which absorbs different colors of light – yet melanin can act as a reflector and cause lasers to burn the skin when used on such complexions.
Recently, filters have been added to lasers in order to increase their wavelength while decreasing frequency, which enables longer wavelengths to penetrate deeper into skin layers without absorption from epidermis cells. Nd:Yag laser is currently considered one of the safest options for hair removal on dark skin as its longer wavelength reduces epidermal melanin absorption while still targeting melanin within hair follicles.
Nd:Yag lasers feature longer wavelengths than most other lasers and can therefore be used at higher fluence without harming hair follicles, while still safely disabling them. Pulse duration is also key as too long pulses risk damaging nearby structures like blood vessels. Unfortunately, human thermal relaxation times have yet to be measured but are estimated in millisecond range.
Nd:Yag can be an effective option for hair removal on dark skin, but it is still essential to consult a medical provider prior to beginning treatment. An experienced dermatologist can assess your skin type and recommend which form of laser hair removal would work best with it as well as provide aftercare instructions to reduce risks like folliculitis or hyperpigmentation.
Poor Absorption into Melanin
1064nm laser wavelengths are not easily absorbed by melanin as red or near infrared light (such as 755 nm alexandrite laser or long pulsed diode lasers), enabling Nd:Yag laser to travel deeper into skin without being absorbed, bypassing pigmentation altogether, and targeting directly the hair follicle, thus making Nd:Yag a very safe option for darker skin tones.
Studies have demonstrated that Nd:Yag can treat dark skin effectively without experiencing side effects like redness, blistering or vesiculation – something especially evident on areas with thinner skin like the axillae where melanin concentration may be less concentrated and better protected by underlying tissues.
Nd:Yag treatment is much safer for mixed race or black skin tones than IPL (intense pulsed light). IPL may cause damage to melanin found in these darker skin types, leading to discoloration. Nd:Yag has a narrow wavelength which penetrates deeper into skin pores to destroy capillaries that support hair follicles and destroy them without harming any melanin molecules in these darker tones.

Pulsed Over the Skin
Laser hair removal devices can effectively treat people of all skin tones; however, those with darker complexions have difficulty finding one without causing pigment changes. Most lasers’ energy absorbs by melanin on the surface of skin which absorbs laser energy and results in burns or hyperpigmentation; however, some manufacturers have released devices using longer wavelengths that don’t pierce epidermis and damage melanin directly – long-pulsed ND:YAG lasers have become increasingly popular choices for dark-skinned users looking for hair removal solutions.
Nd:Yag wavelengths aren’t easily absorbed by melanin, enabling them to pass through the skin’s surface to reach deeper melanin deposits within hair follicles – bypassing epidermis where most melanin is found and still producing enough heat to cause destruction of follicular structures – penetrating 5-7mm into dermis for maximum results, according to Karavolas.
Nd:Yag lasers feature epidermal cooling devices to lower the risk of damage to the surface and melanin underneath, helping minimize risk. While cooling devices don’t guarantee zero irritation after each pulse, they will significantly decrease chances of post-treatment hyperpigmentation and ensure an enjoyable experience for you.
Nd:Yag lasers have been shown to be safer than Alexandrite or diode lasers when used at lower fluences and shorter wavelengths on patients with Fitzpatrick skin phototypes IV-VI. Alexandrite or diode lasers tend to focus too heavily on targeting melanin, potentially resulting in burns or permanent skin discoloration if used on darker skin tones; their use should therefore be limited for darker skin tones to avoid burns or even discoloration of permanent discoloration of melanin-rich tissues, while diode or Alexandrite lasers should not be recommended due to melanin targeting; instead opting for something safer is safest option is recommended over Alexandrite/diode lasers as their usage can cause burns or permanent skin discoloration due to being too focused on targeting melanin molecules directly, potentially leading to burns or permanent discoloration from melanin-rich areas on dark skin tones due to too intense targeting melanin targets too quickly and therefore can result in burns or even permanent skin discoloration causing burns or permanent discoloration permanently discoloration or permanent pigment discoloration from melanin targeting melanin, making these lasers unsafe compared to alexite or diode lasers as their usage is less focused on targeting melanin-rich targetting only melanin and not recommendable enough in terms of targeting melanin; therefore making these safer lasers may cause burns or even permanent discoloration caused by them being targeted enough causing burns due to burns or discoloration or discoloration or permanent discoloration from permanent skin discoloration from permanent discoloration, burns without harm or permanent discoloration or permanent discoloration more suitable to be suitable when treating darker skin to target as diode lasers intended, when treating darker skin to use when treating dark skin to target targeted melanin concentration causing harm than diodes which target solely targeted enough leaving no choice recommended or risky burns from permanent discolorations or discolorations or more intense on targeted melanin to cause burns due to targeted melanin concentration causing burns burn burns discolorations causing burns being burns which cause burn burns for skin discoloration damage or discoloration permanently discoloration or permanent discoloration permanently discoloration or discoloration causing burns discolorations than or for target memelanan in particular pigmentation as could cause burns then to discolorations than others for dark to discolorations, therefore, lasting discolorations than permanent skin discolorations so easily due to so targeted than for either cause burns either or discolorations (more targeted because too easily targeting memelann more likely than ever to produce discolorations in their target melans instead discolorations more likely than permanent discolorations as possible burns than their targetted them as burns possibly burn burns due to more easily burn burn burn burn burn burn burn burn burn burn burn burn burn burn burn burn burn burn burn burn or permanent discolorations!).
At your initial consultation appointment, we will evaluate both your skin tone and hair color to make sure laser treatment is appropriate for you. Additionally, we’ll explain how the Nd:Yag laser works so you know exactly what to expect during your course of treatment; most clients typically achieve 80-90% permanent hair reduction after six sessions with us.
Very Safe
Lasers used for hair removal work by targeting the blood supply that connects with an unwanted hair follicle, causing it to close up and stop producing more hairs – leading to permanent reduction of unwanted hair growth. While earlier laser models targeted melanin too strongly, ND:Yag lasers do not target melanin at all and thus offer safer solutions for all skin types including those with darker complexions.
Studies suggest that Nd:Yag laser treatment is ideal for dark skin tones due to its 1064 nanometer wavelength that does not absorb melanin as easily, enabling light to reach deeper into your skin and reach follicles without damaging surrounding tissue. Both the Cutera Excel Hr and Cutera Xeo come equipped with built-in cooling mechanisms which keep skin surface temperatures down so they do not absorb laser light as readily and prevent overheating of darker skin tones, thus avoiding side effects such as folliculitis (red bumpy bumpy red bumpy red bumpy irritated skin).
One study evaluated the efficacy of long-pulsed Nd:Yag laser irradiation on patients with Fitzpatrick skin phototypes IV-VI who underwent axillary hair removal using Nd:Yag lasers, with hair counts reduced significantly six months post-last treatment session compared to baseline. Furthermore, no adverse posttreatment sequelae occurred such as fibrosis or scarring as a result.
One study compared long-pulsed Nd:Yag wavelength laser treatment to that of Alexandrite lasers for treating affluent hair in Fitzpatrick skin phototypes III-IV and found that patients treated with the long-pulsed Nd:Yag laser experienced greater reductions in both density and posttreatment pain as compared with those receiving Alexandrite treatments.
