Co2 Laser for Melasma: Risks and Alternatives

Melasma often appears as brown or grey-brown patches on both sides of the face. It can fluctuate with light exposure and hormonal factors. Even if a patch lightens after a procedure, the tendency to develop pigment can remain. This matters when considering an ablative laser such as Co2, because inflammation itself can provoke more pigmentation.

Get the pigment identified first

A group of separate sun spots, pigmentation left after acne and melasma may all look brown in a photograph. They do not have the same cause or respond equally to treatment. Let your GP or dermatologist assess an unexplained change, particularly a single mark that is changing, bleeding or behaving differently from the others.

What does the laser evidence show?

A small split-face study compared fractional Co2 laser plus topical treatment with topical treatment alone. Results from a supervised combination study cannot predict whether standalone Co2 resurfacing will help your melasma. Recurrence and post-inflammatory darkening matter alongside the initial change in colour.

Alternatives worth discussing

Regular protection from ultraviolet and visible light is a central part of melasma care. Ask a dermatologist about an appropriate broad-spectrum sunscreen, including whether a tinted product would suit you, and about topical treatments suitable for your skin. Pregnancy, breastfeeding and other medicines can change which options are appropriate.

If a procedure is still being considered

Ask why this particular device is being proposed, how often the clinician treats melasma in your skin tone and what they would do if it worsened. Agree what follow-up will cover. For someone with recurring patches, a tolerable long-term plan can matter more than briefly clearing the darkest area.
