What should you know about Q switch for melasma?

Melasma causes brown or grey-brown patches, often on the cheeks, forehead, upper lip, or jaw. It can be influenced by light, hormones, heat, and irritation. A Q-switched laser delivers short pulses that target pigment, but melasma may involve pigment at more than one skin depth and can recur after it improves.

Laser is therefore one possible part of a broader plan, not a stand-alone promise of lasting clearance. Excess energy or inflammation can make facial colour look darker or more uneven, particularly in pigment-prone skin.

Ask a dermatologist to confirm that the patches fit melasma and to review pregnancy, hormonal medicines, recent tanning, skincare irritation, and previous treatments. Discuss whether topical care, a gentle laser-toning approach, chemical peel, microneedling, or another skin-brightening plan is more suitable.

Daily broad-spectrum sun protection, shade, and a hat help reduce ongoing light exposure. Use gentle products and avoid picking, burning, or aggressive exfoliation. Keep follow-up visits so treatment can be reduced or changed if the skin becomes irritated.

Contact the treating clinic if patches become rapidly darker, painful, blistered, crusted, or markedly inflamed after treatment. Seek assessment for a single spot that bleeds, changes shape, develops an irregular border, or does not heal, because not every dark patch is melasma.

Ask how the diagnosis was made, what factors may be driving your melasma, which settings and maintenance plan are proposed, how relapse or darkening will be handled, and which non-laser options are appropriate.
