Two very different conditions that look deceptively similar
“I have sunspots” is one of the most common things patients say when they first point to patches of discoloration on their face — and about half the time, what they’re actually describing is melasma. The confusion is understandable: both present as brown or tan discoloration, both are worsened by sun exposure, and both can feel embarrassing enough that people want them “gone” without first asking what they actually are.
The problem is that melasma and sunspots (technically called solar lentigines) respond to genuinely different treatments — and the wrong approach on melasma in particular can make it noticeably worse.
How to tell them apart
Melasma
- Shape: Larger, blotchy patches with soft, irregular borders — often symmetrical on both sides of the face.
- Location: Classic areas are the cheeks, upper lip, forehead and jawline.
- Trigger: Strongly linked to hormonal shifts — pregnancy, birth control, hormone therapy — in addition to sun and heat exposure.
- Behavior: Tends to fluctuate; it can fade somewhat in winter and flare back with summer sun or hormonal changes.
Sunspots (solar lentigines)
- Shape: Small, well-defined, flat spots — usually round or oval with a crisp edge.
- Location: Anywhere with cumulative sun exposure over the years — face, hands, forearms, chest.
- Trigger: Straightforward cumulative UV exposure over time; no hormonal link.
- Behavior: Tends to be stable and doesn’t fluctuate seasonally the way melasma does.
Why the treatment approach has to be different
Sunspots are, relatively speaking, more straightforward — they respond well to targeted treatments like laser or certain peels because there isn’t a hormonal driver actively fighting the treatment.
Melasma is more delicate. Aggressive treatments — strong lasers, high-strength peels, anything that provokes inflammation — can actually worsen melasma by triggering a rebound in pigment production. This is the single most common mistake we see: someone treats their melasma the way they’d treat a sunspot, and it comes back darker than before.
The right approach for melasma usually combines:
- Strict, consistent daily sun protection (this is non-negotiable and does more work than any single treatment)
- Gentle, targeted topical treatments to regulate pigment production, prescribed and monitored by a dermatologist
- Carefully selected in-clinic treatments, chosen and calibrated specifically for melasma-safe protocols — not the same settings used for sunspots or scarring
- Patience — melasma improves gradually over months, not days
The one thing that helps both
Whichever one you have, daily broad-spectrum sunscreen is the foundation everything else is built on. Skip it, and even the best in-clinic treatment will be working against a losing battle.
Getting an accurate diagnosis
Because the two conditions can genuinely look alike, especially in early stages, a proper in-person or photo-based assessment matters more than guessing from what you see in a mirror. Getting the diagnosis right the first time saves months of using the wrong product or treatment.
