Pigmentation & Dark Spots — Symptoms

What is Pigmentation & Dark Spots?

Uneven skin coloring where certain areas appear darker than surrounding skin

Caused by UV, post-inflammatory hyperpigmentation, and hormones; manifests as melasma, freckles, age spots, and acne marks.

Main causes & characteristics

Pigmentation appears as partly darkened areas as melanocytes overreact to UV, heat, and inflammatory signals, over-producing and accumulating melanin. It is known that the pattern and depth differ depending on the trigger — UV-related melasma and freckles, post-inflammatory hyperpigmentation, melasma from hormonal changes, and so on.

How to manage

Consistently using ingredients known to help even out tone, such as vitamin C, niacinamide, arbutin, and tranexamic acid, and above all being thorough with daily sun protection, is generally recommended. Because pigment does not change much in a short time, patience to manage it consistently over a span of several months is needed.

Good to know alongside

It is related to melasma, freckles, age spots, acne marks (PIH), and accumulated UV exposure. If the pigment border is irregular or it grows quickly, consulting a dermatologist instead of self-judgment is recommended.

Everyday care tips

Applying sunscreen even indoors and on cloudy days, reapplying every 2–3 hours, and using a wide-brimmed hat and parasol together when out, can help reduce the pigment burden.
