Melasma, sun spots, or post-acne pigmentation: why one “pigment laser” does not fit all

Calling every brown mark a “spot” makes the consultation sound simple but leaves the plan unclear. A sharply defined spot, diffuse melasma, and pigmentation left after acne or irritation have different causes and recurrence patterns. The condition being treated should be identified before choosing a laser name.

The same brown colour is not one problem

• Melasma — broad, irregular, often symmetrical facial pigmentation influenced by several factors including ultraviolet exposure, hormones, heat, and irritation.
• Defined spots — a group that can include different conditions such as sun- or age-related spots and freckles.
• Post-inflammatory hyperpigmentation — colour left where acne, injury, or irritation has settled.

These can be difficult to separate from a photograph, and another skin condition can sometimes resemble pigmentation. Recheck any plan that proposes treating every brown area aggressively without an examination.

Melasma may not respond well to “erase it harder”

Melasma can darken again after it fades, and irritation can sometimes make pigmentation worse. Laser or light therapy may be one part of a plan, often considered alongside sun protection and topical treatment. Ask how the plan changes if pigmentation worsens rather than accepting a promise that a fixed number of sessions will erase it.

Post-acne marks require a plan for new inflammation

Fading old pigment while acne continues means new marks may keep accumulating. Record one plan for reducing active acne and another for the colour already left behind. Products and procedures that sting or inflame the skin can worsen dark marks, so disclose current skincare and medicines.

Skin tone and the travel itinerary affect settings

Possible laser complications include burns, scarring, and skin colour changes. People with darker skin tones may need particular care around darkening or lightening after treatment. Discuss recent tanning, outdoor plans, and how your skin responded to previous pigment procedures. A trip filled with beaches, hiking, or outdoor festivals should be considered when selecting timing and intensity.

Five things the consultation record should contain

• The diagnosis or suspected type for each group of marks
• Why laser, light, topical treatment, or a combination was selected
• Exact device, area, and planned interval
• Sun protection and products to pause
• Who to contact if marks darken or blistering and pain develop
