Melasma is a common skin condition that causes brown or grayish-brown patches, usually on the face, when pigment-producing cells overproduce melanin. It is driven mainly by sun exposure, hormones, and heat, and it tends to be chronic and easily worsened by anything that inflames or heats the skin, including certain laser settings.
What Melasma Actually Is
Melasma is a pigmentation disorder in which melanocytes, the cells that make the pigment melanin, become overactive and deposit excess color into the skin. The result is symmetrical brown or gray-brown patches, most often across the cheeks, forehead, upper lip, and bridge of the nose. It is far more common in women and in people with medium to deeper skin tones, though anyone can develop it.
Several triggers tend to drive melasma at the same time. Ultraviolet and visible light from the sun are major factors, which is why patches often darken in summer. Hormonal shifts from pregnancy, birth control, or hormone therapy play a large role, and heat itself, whether from the sun, hot environments, or heat-generating skin treatments, can provoke or worsen it. Because of this, melasma is usually a chronic, relapsing condition rather than a one-time blemish.
- Caused by overactive pigment cells producing excess melanin, not by ink or an external stain.
- Common triggers include sun and visible light, hormones, and heat.
- More frequent in women and in medium to deeper skin tones, and tends to recur.
Why It Matters for Tattoo and Scar Removal
Melasma matters in laser work because it is a pigment condition that lives in the same skin you are asking a laser to treat. Aggressive or poorly chosen laser energy can inflame melasma-prone skin and trigger post-inflammatory hyperpigmentation, a darkening that appears after the skin is irritated. That is a real consideration during tattoo removal, scar treatment, or pigment work, especially for the medium and deeper skin tones where melasma is most common.
It also matters because melasma can be mistaken for, or sit alongside, the very discoloration people come in hoping to reduce. A brown patch is not always what it first appears to be, and treating pigment without understanding its cause can make things worse rather than better. This is one reason a careful, physician-led assessment of skin type and pigment history comes before any laser plan.
We want to be honest here: melasma is notoriously stubborn, complete clearance is not guaranteed for anyone, and the goal of good care is safe, gradual improvement while protecting the surrounding skin, not a rushed or overpromised result.
How Laser Eraser Approaches Melasma-Prone Skin With PicoWay
Every treatment at Laser Eraser is performed by a physician, not a spa technician, and that starting point matters most for pigment-sensitive skin. A doctor evaluates your skin type, pigment history, and any signs of melasma first, then decides whether and how to treat, rather than applying one setting to everyone.
For tattoo removal we use the PicoWay picosecond laser, which delivers energy in ultra-short pulses to shatter pigment into finer particles with less heat buildup than older, longer-pulse lasers. Lower thermal load is exactly what melasma-prone skin needs, and settings are customized to your Fitzpatrick skin type and the colors being treated. Treatment is staged across the sessions your case calls for, with time between visits so your skin can respond and your care team can adjust the plan. If you have melasma or a history of skin darkening after previous procedures, your free consultation is the place to raise it before anything begins.
Frequently asked questions
Laser Eraser focuses on physician-led laser tattoo and pigment removal, and melasma is an important factor a doctor evaluates before any treatment. Because melasma is chronic and easily worsened by heat, our physicians assess it during your free consultation and plan conservatively. If melasma is your primary concern, we will give you an honest picture of realistic options.
