Dark spots are not one single condition. A flat mark after acne, a sun spot and melasma can all look like “pigmentation”, but they behave differently and may need different treatment. The safest starting point is a gentle routine, consistent sun protection and realistic expectations.
First, understand what you are looking at
Post-inflammatory hyperpigmentation (PIH) can appear after acne, irritation or injury and often fades slowly over time. Melasma is usually more symmetrical and is influenced by UV, visible light and hormonal factors. New, changing, irregular or raised pigmented lesions should not be self-treated as “dark spots”—they should be assessed.
Sun protection is treatment, not an optional extra
UV exposure can deepen existing pigmentation and make improvement slower. For melasma and some forms of hyperpigmentation, visible light can also matter. AAD guidance recommends broad-spectrum SPF 30+ and notes that tinted sunscreen with iron oxides can help protect against visible light.
Choose one main active and give it time
Common cosmetic options include vitamin C, niacinamide, azelaic acid, alpha-hydroxy acids and other brightening ingredients. Retinoids can also help in appropriate routines. More actives do not necessarily produce faster results; irritation itself can worsen pigmentation, especially in skin prone to PIH.
Start slowly, especially with acids or retinoids, and avoid introducing several strong products in the same week.
Do not confuse exfoliation with erasing pigment
Exfoliation can improve surface texture and help some routines, but aggressive scrubbing or frequent peels can damage the barrier. If a product burns, stings persistently or leaves the skin inflamed, stop and reassess. “Tingling” is not proof that a product is working.
How long does improvement take?
Think in months rather than days. PIH often fades gradually. Melasma is usually chronic and may recur. Consistency with sunscreen and a tolerable routine is more valuable than frequently changing products because a new serum promises faster results.
When to see a dermatologist
Seek assessment for pigmentation that is new and changing, asymmetric, raised, bleeding, itchy or otherwise unusual. A dermatologist can also confirm melasma, distinguish pigment from scarring and discuss prescription or procedural options when skincare is not enough.
Build a focused routine
You can compare Dark Spots & Uneven Tone products and pair them with appropriate Sun Protection. Choose a serum, moisturiser and sunscreen you can use consistently instead of collecting five overlapping treatments.
