Sun Spots, Melasma, or PIH?
Dark spots can feel like a mystery. Whether they show up after a vacation, during pregnancy, or after a breakout, each type has a different cause and needs a different approach. Knowing what kind of spots you have is the first step to building an effective LED and skincare routine that actually works.
Sun spots — signs of sun exposure
Sun spots, also called solar lentigines, are flat brown or dark patches that appear on areas frequently exposed to the sun like the face, chest, and hands. They result from years of UV damage and are more common as we age. Unlike freckles, they don’t fade in winter and tend to get darker over time if not protected.
These spots usually respond well to brightening treatments, including LED therapy, as long as strong sun protection is used to prevent new spots.
Melasma — the hormonal connection
Melasma appears as larger, symmetrical patches of brown or gray-brown pigmentation, usually on the cheeks, forehead, or upper lip. Hormones play a big role — pregnancy, birth control pills, or hormone fluctuations can trigger or worsen it.
Sun exposure makes melasma worse, so strict sun protection is crucial. Melasma is stubborn and may return even after successful treatment. Combining LED therapy with gentle brightening agents and long-term lifestyle adjustments gives the best chance at keeping it under control.
Post-inflammatory hyperpigmentation (PIH) — the acne aftermath
PIH happens when the skin produces excess pigment after inflammation or injury. Common triggers include acne, eczema, or even harsh treatments like aggressive peels.
Unlike melasma, PIH tends to be more localized and fades slowly over time. LED therapy can help speed up this fading by reducing inflammation and supporting skin healing. Using calming products and avoiding picking or scratching are essential to prevent new marks from forming.
Why correct diagnosis matters
Treating the wrong type of pigmentation can lead to frustration and wasted time. Sun spots may improve quickly with brightening products and LED, but melasma needs a much more careful, long-term plan. PIH responds well to anti-inflammatory support but can worsen if overtreated.
Knowing exactly what you’re dealing with means you can choose treatments that match your skin’s needs, avoid irritation, and see real progress faster.
Conclusion
Learning to spot the difference between sun spots, melasma, and PIH is the foundation for an effective hyperpigmentation plan. Once you understand your skin’s story, you can choose the right LED strategy and supportive treatments with confidence.
