If you have medium, olive, brown, or deep skin, you may have heard that lasers "aren't for you." Maybe a friend got dark spots after a laser treatment, or a clinic told you to look elsewhere.
That worry is understandable, but it isn't the whole story. With the right approach, fractional laser can treat a wide range of skin tones. This article explains what fractional laser actually does to your skin, what changes you can expect week by week, and how we keep treatment safe for every skin tone we see in Queens.
What is fractional laser?
Fractional laser is a skin treatment that improves texture, tone, and fine lines by encouraging your skin to renew itself.
Here's how it works, in plain language:
The laser treats tiny dots of skin, not the whole surface. Instead of heating your entire face at once, it creates thousands of microscopic treatment zones, with healthy skin left untouched between them.
Your skin starts repairing those tiny zones. That healing response triggers new collagen, the protein that keeps skin smooth and firm.
The untouched skin speeds up healing. Because most of your skin isn't treated, recovery is faster than with older, full-surface lasers.
Fresh, smoother skin builds over time. Over the following weeks, texture, tone, and fine lines gradually improve.
The word "fractional" simply means the laser treats a fraction of the skin at a time.
What fractional laser does to your skin
Your skin has two main layers. The epidermis is the thin outer layer you see and touch. It holds your skin's color, surface texture, and sun damage. The dermis sits underneath. It's packed with collagen and elastin, the fibers that keep skin smooth, firm, and bouncy.
As we age, and with sun exposure, acne, or scarring, both layers change. The surface gets rough and uneven, and the collagen underneath breaks down. Fractional laser works on both layers at once:
On the surface, it helps your skin shed old, damaged cells faster. That clears the way for fresher, more even-toned skin.
Deeper down, the gentle heat wakes up your skin's repair process. Your skin responds by building new collagen and remodeling old, damaged collagen, like replacing worn-out padding with new.
The treatment is non-ablative, which means it works under the surface without removing the top layer of skin. That's why recovery takes days, not weeks.
At Astoria Esthetics, we perform fractional laser with the Candela Nordlys, which lets your provider adjust how deep the laser goes based on what your skin needs.
How your skin changes, week by week
Days 1–3: Warmth and redness. Your skin may look and feel like it has a mild sunburn, with some swelling. This is a sign the healing process has started.
Days 3–7: The surface renews. Your skin may feel rough, like fine sandpaper. You might notice tiny dark specks, which are old, damaged cells working their way out. They flake off on their own.
Weeks 2–4: A fresh glow. Once the flaking is done, skin looks brighter and feels smoother. Makeup goes on more evenly.
Months 1–3 and beyond: Collagen builds. New collagen keeps forming for months after treatment. This is when deeper changes, like softer scars, smaller-looking pores, and fewer fine lines, become visible.
That's also why fractional laser is usually done as a series. Each session builds on the collagen from the last one.

Can fractional laser be used on all skin tones?
Yes. With the right laser and the right settings, fractional laser can be used across all skin tones, from very fair to deep. Here's why.
Why some lasers are risky for darker skin Many lasers are drawn to melanin, the pigment that gives skin its color. Darker skin has more melanin, so those lasers can overheat the skin and leave dark marks behind. This is called post-inflammatory hyperpigmentation, or PIH.
Why fractional laser can work for darker skin The wavelength used for deeper resurfacing targets water in the skin, not pigment. Because it doesn't go after melanin, it's considered suitable for darker skin types. A study from a New York City hospital reviewed 115 treatments with this type of fractional laser in patients with brown and deep skin and found a low risk of dark marks. A 2026 review of 15 studies also supported this type of laser for skin of color.
What makes the difference: settings Research shows the risk of dark marks goes down when lower energy and density are used on darker skin. That's why we never use one setting for everyone. For deeper skin tones, your provider may:
Use gentler energy levels and fewer passes
Space sessions further apart
Recommend a series of lighter treatments instead of one strong one
Suggest a skin-prep routine before and after treatment
One note: the shallower setting used mainly for sunspots and age spots is cleared for light to medium skin tones. If you have deeper skin, your provider will focus your plan on deeper resurfacing instead. Your consultation is where we match the right approach to your skin.
Quick answers
Will fractional laser make my dark spots worse?
In the right hands, the risk is low. Using the right wavelength and gentler settings for your skin tone is what keeps it low.
How many sessions will I need?
Most people need a series of treatments spaced several weeks apart. Your provider will recommend a plan based on your skin and goals.
Is there downtime?
Because the treatment is non-ablative, downtime is usually a few days of redness and light flaking, not weeks.
