Melasma is driven by ongoing internal signals. PIH fading speed depends on your internal inflammatory and nutrient environment. Why the type you have determines how much your internal health matters.
These two types of hyperpigmentation can look almost identical on the surface. Underneath, they are driven by completely different mechanisms, and treating one like the other is one of the most common reasons pigment stalls or gets worse.
Heat worsens melasma. Heat also causes pigmentation on its own. The overlap is real, which is exactly why this distinction is worth understanding.
Melasma fluctuates with hormones and seasons. Sun spots stay exactly the same. If your facial pigmentation comes and goes, it is not sun damage behaving normally. It is melasma.
Melasma behaves differently from every other type of hyperpigmentation. Understanding its triggers, its depth, and its relapse pattern is what separates progress from years of frustration.
Melasma doesn't follow a straight line. Understanding why helps you stop chasing the wrong benchmarks and start managing it on its terms.
PIH and melasma look similar but behave nothing alike. Applying the wrong timeline expectations is one of the most common reasons people give up too early.
Heat activates melanocytes without UV. The mechanism is vascular and inflammatory, and it explains why pigmentation worsens in conditions that have nothing to do with sunlight.
Melasma does not behave like other hyperpigmentation. The treatments that work for dark spots from breakouts can make melasma worse. Here is what actually works, and what the treatment journey really looks like.
Treating melasma the same way you treat a post-acne mark is one of the most common reasons pigmentation gets worse instead of better.
