Uneven skin tone, dark spots, and patches of pigmentation are some of the slowest skin concerns to resolve — and one of the easiest to make worse with the wrong approach. Whether it's sun spots, acne marks, or melasma, pigmentation forms deep in the skin and takes time, the right actives, and daily protection to fade. Here's what's actually happening under the surface, and how to treat it properly.
What Causes Pigmentation & Dark Spots?
Pigmentation occurs when your skin produces excess melanin in response to a trigger. Common causes include:
- UV exposure — the single biggest driver of dark spots and uneven tone, even on cloudy days or through windows
- Post-inflammatory hyperpigmentation (PIH) — dark marks left behind after acne, cuts, insect bites, or picking at the skin
- Hormonal changes — melasma linked to pregnancy, birth control, or hormonal fluctuations often appears as symmetrical patches on the cheeks and forehead
- Natural aging — sun spots and age spots accumulate with years of cumulative UV exposure
- Friction or irritation — repeated rubbing or harsh exfoliation can trigger dark patches over time
What To Do About It
Fading pigmentation is a long game — skin renews on a 4–6 week cycle, so results take time and consistency. Focus on:
- Daily broad-spectrum sunscreen, non-negotiable. Without SPF, any brightening routine will be undone by new UV-triggered pigmentation
- Brightening actives like Vitamin C, niacinamide, arbutin, and tranexamic acid to inhibit melanin production
- Gentle exfoliation to support cell turnover — avoid harsh scrubbing which can worsen PIH
- Never pick at blemishes or scabs, which significantly increases the risk of dark marks
- Patience — visible fading typically takes 8–12 weeks of consistent use

Consider a Professional Therapy
For more stubborn or widespread pigmentation, the Derma NZ Whitening Therapy is an intensive brightening system powered by glutathione, tranexamic acid, and Vitamin C to target discoloration more comprehensively than single products alone.
