Pigmentation is often used as a catch-all term for any dark spots (because it literally means “to be pigmented”) or uneven tone on the skin. Melasma is usually lumped into the same category.
Understanding the difference matters because they are triggered differently, behave differently, and respond to treatment differently. What works for one does not always work for the other.
Melasma is a type of pigmentation, but not all pigmentation is melasma.
What they do share is two major enemies: heat and sun.
Common types of pigmentation include:
Post-Inflammatory Hyperpigmentation (PIH)
The dark “love letters” from your deceased acne, irritation, rashes, or injuries. Inflammation triggers melanin production during the healing process. This can take a very long time to fade, and if left unprotected from the sun, it will darken significantly.
Sun spots (solar lentigines)
Brown spots caused by cumulative sun exposure over time. They develop slowly and become more noticeable with age. That summer you spent by the pool tanning with Sun-In in your hair and baby oil on your shoulders? Yeah… that tends to show up in your 40s.
Freckles
The cute kind. Small pigment clusters that darken with sun exposure and lighten when sun exposure decreases. Genetics play a big role, but UV will always worsen them.
Melasma
The hardest one to tackle because it largely comes from inside. Melasma is a chronic pigmentation condition driven by hormones combined with sun and heat exposure. Living in Singapore or Southeast Asia makes this exponentially worse because there is very little seasonal break from UV and heat.
It appears in larger patches on the cheeks, upper lip, forehead, and jawline. Many women first notice melasma during pregnancy or periods of hormonal change combined with sun exposure (notice the theme).
Melasma also tends to return easily and can be extremely stubborn to fade. Treatments that involve heat, like certain lasers, often make it worse.
So what’s the plan of action?
For regular pigmentation (PIH, sun spots, freckles):
✔ Daily sun protection
✔ Gentle exfoliation
✔ Pigment-regulating ingredients such as Vitamin C (L-ascorbic acid), niacinamide, alpha arbutin, azelaic acid, AHAs, BHAs, and retinoids
✔ Time and consistency
For melasma:
✔ Very strict sun and heat protection
✔ Barrier-supporting skincare
✔ Carefully chosen actives such as hydroquinone (prescription and cycled), tranexamic acid, azelaic acid, and tretinoin
✔ Avoiding overheating (sorry hot yoga… and be cautious with infrared or heat-based masks)
✔ A long-term maintenance mindset
Here’s our pitch (from two women who battle sun spots, PIH, and melasma daily and still love being outdoors):
You MUST have complete and consistent physical protection on high-risk areas, especially if you are using active ingredients to treat pigmentation.
No laser, serum, or brightening ingredient will work unless it is paired with disciplined UV protection. And if you’re not reapplying sunscreen perfectly all day (most of us aren’t, be honest), physical sun protection becomes your most reliable line of defense.
That’s exactly why sun patches are such a game changer for pigmentation-prone skin.
We love you. We’re in this together.
