Melasma vs Hyperpigmentation: How to Tell the Difference (And Why It Matters)
Summary:
Melasma and hyperpigmentation are biologically different. Treating melasma like standard pigmentation often increases relapse and instability.
What Is Hyperpigmentation?
Hyperpigmentation is pigment darkening following:
- Acne
- Injury
- Inflammation
- Post-procedure healing
It is typically localised and responsive to exfoliation.
What Is Melasma?
Melasma:
- Appears symmetrically
- Is hormonally influenced
- Is heat-sensitive
- Frequently recurs
- May involve dermal pigment
Why Misdiagnosis Leads to Worsening
Treating melasma with:
- Frequent resurfacing
- High-strength acids
- Heat-based procedures
May increase melanocyte reactivity.
Correct diagnosis informs safe strategy.
Key Signs It’s Melasma
- Bilateral cheek patches
- Upper lip shadow
- Pigment deepening with heat
- Hormonal timing
If in doubt, conservative management is safer than escalation.
