Candela Laser for Dark Skin: Why New Day Medspa Uses It

A lot of people with darker skin tones have been turned away from laser hair removal clinics or had a bad experience with burns, discoloration, or zero results. That history is real and worth acknowledging. The problem was almost always the laser, not the skin. Older devices were not built with darker skin in mind. Candela technology changed that calculus significantly, and it is the reason New Day Medspa in Jacksonville chose it as the platform for all laser hair removal treatments. This guide explains what Candela does differently for darker skin tones, what the science behind it actually says, and what to expect if you come in with Fitzpatrick IV, V, or VI skin.

Key takeaways

The Candela® Gentle Pro Series uses two wavelengths: the 755 nm Alexandrite for lighter skin tones and the 1064 nm Nd: YAG for darker skin tones (Fitzpatrick IV through VI).
The 1064 nm Nd: YAG bypasses melanin in the epidermis and targets the hair follicle directly, dramatically reducing the risk of surface skin damage that made older lasers unsafe for darker skin tones.
A peer-reviewed study published in the Journal of Drugs in Dermatology (Chan and Dover, 2013) confirmed that, with the right settings, the 1064 nm Nd:YAG laser in the Candela® Gentle Pro Series produces effective laser hair removal for Fitzpatrick skin types IV through VI.
The Dynamic Cooling Device (DCD) in the Candela system fires a burst of cryogen spray before each laser pulse, protecting the skin surface during treatment, which matters even more on melanin-rich skin where the margin for error is smaller.

Why Darker Skin Tones Are More Challenging for Laser Systems

Laser hair removal works by targeting melanin in hair follicles and converting light into heat. The heat damages the follicle, reducing its ability to produce hair. The complication for darker skin is straightforward: melanin is also present in the skin itself, not just the follicle.

Older laser systems used shorter wavelengths that were absorbed heavily by surface melanin. For patients with Fitzpatrick I through III skin, the contrast between the pigment in the follicle and the skin was high enough that the laser could pick one over the other. For Fitzpatrick IV-VI patients, the contrast is much smaller. The skin and the follicle both contain significant melanin, and early devices could not reliably distinguish between them. The result was heat in the wrong place: burns, hyperpigmentation, and blistering.

The reputation that laser hair removal was not safe for dark skin came directly from this period. Real clinical outcomes from the wrong devices earned it. That is not the same as the technology being fundamentally unsuitable. It means the wrong wavelength was being used.

What Makes the Candela 1064 nm Nd: YAG Different

The Nd: YAG laser operates at 1064 nm. That wavelength sits in the near-infrared range, significantly longer than the 755 nm Alexandrite or 800 nm diode lasers most commonly associated with early laser hair removal problems in darker skin.

Longer wavelengths penetrate deeper into tissue before being absorbed. At 1064 nm, the laser passes through the melanin-rich upper layers of the skin with minimal absorption and reaches the hair follicle at the dermal level, where the target is. The energy is deposited where it is supposed to go.

Melanin absorption at 1064 nm is considerably lower than at 755 nm. This is the physics that makes Nd: YAG safe for darker skin. It is not a safety feature added on top of the device. It is a function of the wavelength itself, which is why 1064 nm has become the clinical standard for Fitzpatrick IV-VI treatment across dermatology.

What Does the Candela® Gentle Pro Series Actually Contain?

The Candela® Gentle Pro Series includes dual-wavelength platforms housing both the 755 nm Alexandrite and the 1064 nm Nd: YAG. The provider selects the appropriate wavelength based on your Fitzpatrick skin type at consultation. The provider selects the appropriate wavelength based on your Fitzpatrick skin type at consultation.

For Fitzpatrick I through III, the Alexandrite is typically used. High melanin absorption makes it highly effective on lighter skin where the risk of epidermal damage is low.

For Fitzpatrick IV-VI, the Nd: YAG at 1064 nm is used. The deeper penetration and reduced absorption by epidermal melanin make it the right tool for melanin-rich skin. It requires slightly higher energy settings to achieve the same level of follicle damage, but that trade-off is clinically well understood and manageable with proper calibration.

The Dynamic Cooling Device is the other critical component. A fraction of a second before each laser pulse, the DCD sprays a burst of cryogen coolant onto the skin surface. This pre-cools the epidermis, protecting it from thermal damage during the pulse. On darker skin especially, where epidermal protection is already the main clinical concern, the DCD is not incidental to safety. It is a structural part of how the system works.

What the Research Says About Candela and Dark Skin

A clinical paper published in the Journal of Drugs in Dermatology (Chan CS, Dover JS, 2013) directly addressed laser hair removal in Fitzpatrick skin types IV through VI using the 1064 nm Nd:YAG laser from the Candela® Gentle Pro Series. The authors concluded that with the right treatment settings, darkly pigmented individuals can undergo laser hair removal effectively.

‍Candela Laser by Fitzpatrick Skin Type: Which Wavelength and Why

Fitzpatrick type	Skin description	Wavelength used	Why
Type I and II	Very fair to fair	Alexandrite 755 nm	High melanin contrast; deep penetration not required
Type III	Medium, tans gradually	Alexandrite 755 nm	Strong results with manageable parameters
Type IV	Olive to light brown	Nd: YAG 1064 nm preferred	Reduced epidermal absorption; DCD protects the surface
Type V and VI	Brown to dark brown to black	Nd: YAG 1064 nm only	Deepest reach with minimal surface disruption

Expert tip: When patients with darker skin tones ask whether the Nd: YAG will feel different from what they have heard about other lasers, the honest answer is yes. The 1064 nm wavelength requires slightly more energy to achieve the same follicle damage because less of it is absorbed by melanin. Some patients find it feels slightly more intense than shorter-wavelength lasers. That is expected and is not a sign that something is going wrong. The DCD cooling manages surface temperature throughout, and providers can adjust settings between sessions based on how your skin responds.

Book a complimentary consultation at New Day Medspa, where a licensed ARNP or PA assesses your Fitzpatrick type, selects the right wavelength, and maps out a realistic session plan before anything gets scheduled.

Does Laser Hair Removal Work on Dark Skin at New Day Medspa?

Yes. New Day Medspa in Jacksonville uses Candela technology specifically because it covers the full Fitzpatrick scale, including the darker skin tones that older laser systems could not safely treat. Every new patient receives a Fitzpatrick skin type assessment at their complimentary consultation, and the Nd: YAG wavelength is selected for Fitzpatrick IV-VI patients as standard protocol.

The providers performing treatments are licensed ARNPs and PAs, not aestheticians or unlicensed technicians. On darker skin, calibration decisions and real-time adjustments during treatment matter more than on lighter skin, where the margin for error is wider. Having medically trained providers in the room is part of what makes the process safe.

‍What to Expect If You Have Darker Skin

A few things differ for darker-skinned patients compared to the standard experience:

A test patch is typically recommended before the first full session, especially for Fitzpatrick V and VI. Your provider observes healing for 24 to 48 hours before proceeding.
Conservative settings are used to start and are increased progressively based on your skin's response. More sessions may be needed to reach the same cumulative follicle damage as a higher setting would produce in one session on lighter skin.
SPF 30 or higher daily between every session is non-negotiable. Jacksonville's year-round sun raises the risk of post-inflammatory hyperpigmentation in treated areas. This is the most common preventable complication, and it is largely avoidable with consistent sun protection.
Visible improvement tends to start around sessions three to four. Darker-skinned patients sometimes see results slightly later than lighter-skinned patients at the same number of sessions, which is normal given the conservative ramp-up in early sessions.

What Does Laser Hair Removal Cost for Patients with Darker Skin?

Pricing is the same regardless of skin tone. At New Day Medspa in Jacksonville, laser hair removal starts at $199 per treatment or as low as $99 per month with financing through Cherry, PatientFi, Afterpay, and Klarna. Darker-skinned patients may need additional sessions in certain areas, which affects the total cost of the series. This is discussed at consultation based on your specific skin type and treatment zones.
