Laser Hair Removal for Dark Skin in Montreal
Institut V Esthétique performs laser hair removal on dark and Black skin in Montreal with the Nd:YAG 1064 nm wavelength of the Clarity II laser, the technology recognized as safe for phototypes IV to VI, at 6532 Rue Beaubien Est in the Mercier district (H1M 1A9).
If a salon has ever turned you away or advised against laser because of your skin colour, this page explains why that refusal belongs to the past, what the real risks are and how we avoid them.
No commitment. Free cancellation up to 24 hours before your appointment.
Why dark skin was long turned away from laser hair removal
Dark skin was long turned away from laser hair removal because older devices targeted melanin without telling apart the melanin in the hair from the melanin in the skin, which exposed darker phototypes to burns and dark spots.
The laser destroys the hair by heating the melanin it contains. On light skin, melanin sits mostly in the hair, so the energy goes to the right place. On dark skin, the epidermis also holds a lot of melanin. Alexandrite 755 nm lasers and intense pulsed light (IPL) devices, which are strongly absorbed by surface melanin, heated the skin as much as the hair. Without a suitable wavelength, many salons chose to refuse dark skin rather than take that risk.
The real risks of laser hair removal on dark skin
The two real risks of laser hair removal on dark skin are a superficial burn and post-inflammatory hyperpigmentation, both caused by energy being absorbed by the melanin in the epidermis rather than by the hair.
- A superficial burn shows up as strong redness, tenderness and sometimes a blister or a crust. It happens when the epidermis receives too much energy or is not cooled enough.
- Post-inflammatory hyperpigmentation is a darker mark that appears where the skin reacted. It can take several weeks to several months to fade. It is the most common complication on darker phototypes that are treated poorly.
- Hypopigmentation, a lighter mark, is rarer but possible when settings are too aggressive.
These reactions are real, but they are largely avoidable. They depend almost entirely on three factors that are under control: the wavelength chosen, settings matched to your phototype and the experience of the person operating the device. That is exactly what we manage at Institut V.
Why Nd:YAG 1064 nm is safe for dark skin
Nd:YAG 1064 nm is safe for dark skin because its longer wavelength passes through the melanin in the epidermis without overheating it and releases its energy deep down, at the hair bulb.
The longer a wavelength is, the less it is absorbed by surface melanin and the deeper it reaches. Nd:YAG 1064 nm is the longest wavelength used in laser hair removal, which makes it the established standard for phototypes IV to VI. It bypasses the melanin of dark epidermis to heat the follicle, where the hair regenerates.
The Clarity II laser used at Institut V combines two wavelengths in a single device: Alexandrite 755 nm for light to medium skin and Nd:YAG 1064 nm for medium to Black skin. On dark skin, your esthetician works with the Nd:YAG and its contact cooling system, which protects the surface of the skin during each pulse.
The Fitzpatrick scale and phototypes IV, V and VI
The Fitzpatrick scale sorts skin into six phototypes based on how it reacts to the sun, and phototypes IV, V and VI cover the medium, brown and Black skin that requires the Nd:YAG wavelength.
| Phototype | Skin type | Reaction to the sun | Suitable wavelength |
|---|---|---|---|
| I | Very fair, often freckled | Always burns, never tans | Alexandrite 755 nm |
| II | Fair | Burns easily, tans little | Alexandrite 755 nm |
| III | Medium | Sometimes burns, tans gradually | Alexandrite 755 nm |
| IV | Olive, Mediterranean or Latino | Burns little, tans well | Nd:YAG 1064 nm |
| V | Dark brown | Rarely burns, tans a lot | Nd:YAG 1064 nm |
| VI | Black | Practically never burns | Nd:YAG 1064 nm |
During the consultation, your esthetician determines your phototype by sight and with a few questions about how your skin reacts to the sun, then chooses the wavelength and settings accordingly.
What a serious clinic must do before treating dark skin
Before treating dark skin, a serious clinic must assess the phototype, run a patch test on a small area, adjust the laser settings and provide aftercare instructions.
- Assess the phototype and history: skin colour, reaction to the sun, recent tanning, photosensitizing medication, history of dark spots. This assessment decides the wavelength and the settings.
- Run a patch test: a few trial pulses check how your skin reacts before treating a full area, especially at the first session.
- Adjust the settings to your skin: Nd:YAG wavelength, fluence, pulse duration and cooling are set for your phototype, never applied as a generic protocol.
- Provide aftercare: avoid the sun and tanning beds, apply sunscreen to exposed areas, do not wax or pluck between sessions, and report any unusual reaction.
You will find the full grid of areas, session length and prices on our laser hair removal in Montreal page. All of these areas can be treated safely on dark skin with the Nd:YAG.
Frequently asked questions about laser hair removal for dark skin
Is laser hair removal really safe on dark skin?
Yes, when it is performed with the Nd:YAG 1064 nm wavelength. This wavelength passes through the melanin in the epidermis without overheating it and releases its energy deep down, at the hair bulb, which makes it safe for phototypes IV to VI. The Clarity II laser used at Institut V includes this wavelength.
How many sessions are needed on dark skin?
On average 6 to 8 sessions spaced 4 to 8 weeks apart, the same as for other phototypes. Hair grows in cycles and the laser only acts on hairs in the active growth phase, which is why several sessions are needed. Your exact plan is set during the free consultation.
Can laser hair removal cause dark spots on Black skin?
The risk of dark spots (post-inflammatory hyperpigmentation) mainly exists when an unsuitable wavelength or setting overheats the epidermis. It becomes very low with the Nd:YAG 1064 nm wavelength, settings adjusted to your phototype, a patch test and clear aftercare. This is why the technology and the operator matter as much as the laser itself.
Can you treat tanned skin with the laser?
Recently tanned skin holds more active melanin in the epidermis, which raises the risk of a reaction. We assess your skin during the consultation and adjust the wavelength and settings. In some cases we recommend waiting for the tan to fade before treating certain areas.
Does the laser help with ingrown hairs on the face and neck?
Yes. Ingrown hairs and shaving irritation often affect darker skin on the chin, neck and bikini area. By durably reducing hair density, laser hair removal lowers ingrown hairs and the marks they leave, provided a wavelength that is safe for the phototype is used.
Who performs the treatment at Institut V?
The treatment is performed by Alexandra Vivanco, founder and lead esthetician, who holds a DEP in esthetics (2018) and a Cynosure certification on the Clarity II laser (2024). Every treatment plan starts with a free consultation to assess your phototype and eligibility.
Safety and supervision of your laser treatment
Your laser treatment at Institut V Esthétique is performed by Alexandra Vivanco, founder and lead esthetician, who has practised esthetics since 2018 and operates the Clarity II laser herself.
Alexandra holds a DEP in esthetics earned at École Antoine-de-Saint-Exupéry in 2018 and a Cynosure certification on the Clarity II laser earned in 2024. Laser consultations and laser treatments are her daily focus: assessing the skin, choosing the wavelength for the phototype, setting the device and following up on results.
In practice, this supervision means the person who assesses your phototype at the consultation is the same person who sets and operates the laser during the session. Every treatment plan starts with a free consultation, and you can read more about Institut V and its approach before your first appointment.
