Melasma (Q-Switched Laser)

Adults with epidermal or mixed melasma seeking a device-based adjunct to dermatology-led treatment. Best for stable melasma with strict sun protection and skincare adherence. Not recommended during pregnancy/breastfeeding, immediately after suntan, or for unstable/inflamed melasma.

Q-Switched nanosecond pulses create a photoacoustic effect that fragments excess melanin into smaller particles that the skin can clear naturally, while minimizing heat in the epidermis. Used conservatively (often low-fluence ‘laser toning’), it complements topical depigmenting agents to reduce recurrence.

Typical protocols are 4–6 sessions spaced 2–4 weeks apart, adjusted to skin type and response. Visible lightening is gradual over 4–8 weeks. Because melasma is relapsing, maintenance (e.g., every 1–3 months) plus daily SPF and a medical depigmenting routine are key to durability.

Expect progressive brightening and a more even tone rather than a sudden ‘erase’. Durability depends on UV/visible light exposure, heat, hormones, and skincare adherence. With strict protection and maintenance, results can be sustained; without them, relapse is common.

Downtime is minimal. Mild redness and warmth are common for hours; pigment can transiently darken before lifting. The main risk is post-inflammatory hyperpigmentation (PIH), especially in higher phototypes or if parameters are too aggressive. Conservative energy, test spots, and diligent SPF lower this risk.

Avoid if pregnant/breastfeeding, recently tanned, with active dermatitis/infection, or if you’ve used isotretinoin recently (follow medical guidance). Photosensitizing drugs warrant caution. Darker phototypes require experienced parameter selection and strict aftercare to minimize PIH.

Yes—combination care is the standard. Topicals such as hydroquinone (or HQ-free alternatives like azelaic, kojic, arbutin), retinoids, vitamin C, and tranexamic acid (topical or oral under medical supervision) improve outcomes. Gentle chemical peels can be alternated. Your clinician will design a protocol to minimize inflammation.

Before: strict daily SPF 50+, no sun/self-tanner (2 weeks/10–14 days), and pause harsh actives 3–5 days unless otherwise advised. After: gentle cleanser and moisturizer, SPF 50+ with reapplication, avoid heat and strenuous exercise for 24–48h, do not pick at darkening areas, and reintroduce depigmenting topicals per your clinician.
