Melasma vs. sun spots: how to tell the difference
Melasma vs sun spots is not just a visual distinction. They share a UV trigger but differ in pattern, persistence and how they respond to correction. Reading the pattern first can prevent months of unsuitable care.

Pattern
Melasma appears as larger, symmetrical patches, usually across the cheeks, forehead and upper lip.
Sun spots are smaller, discrete and asymmetrical, concentrated where exposure is highest.
“Pigmentation care starts with identifying the pattern, then controlling the UV trigger every day.”
Triggers
Both are UV-driven. Melasma is additionally amplified by hormonal change, which is why pregnancy and hormonal therapy often precede it.
Treatment timelines
Sun spots typically respond faster to consistent correction. Melasma is chronic and recurrence-prone; without daily SPF, results reverse.
MCLEAN supports a pigment-correction routine. WIN-T helps protect against the UV trigger. Neither step works well in isolation.
Common questions
What readers usually ask
What pattern is more typical of melasma?
Melasma usually appears as broader, symmetrical patches across areas such as the cheeks, forehead or upper lip.
Can sun protection help prevent pigmentation from returning?
Consistent broad-spectrum sun protection helps reduce the UV trigger that can deepen both melasma and sun spots.
