Why Your Dark Spots Aren't Going Away

Most "dark spots not fading" problems aren't a product failure. They're a diagnosis problem, a routine problem, or an expectation problem. Here are the 7 most common reasons, ordered by how often we see them on Fitzpatrick V–VI.

1. You're treating the wrong condition

On melanin-rich skin, at least three things look like "dark spots" but respond to different treatments: PIH (post-inflammatory hyperpigmentation), PIE (post-inflammatory erythema), and melasma. Vitamin C works on PIH. PIE needs vascular-targeted ingredients. Melasma needs deeper-acting actives like tranexamic acid. If you're treating melasma like it's PIH, you'll see 3% improvement after 6 months — same as doing nothing.

Fix first: figure out exactly what kind of pigmentation you have. Lumière scans your skin and identifies it in 30 seconds.

2. You're skipping sunscreen

This is the single biggest reason routines fail. Every active that fades dark spots (vitamin C, niacinamide, azelaic, tranexamic acid, retinoids) works by quieting melanocytes. UV exposure — even 10 minutes a day, even through a window — wakes them up again. You're playing tug-of-war with your own skin.

Fix: SPF 30+ every single morning. Use a sunscreen without white cast specifically formulated for darker skin. Visible light (not just UV) drives melasma, so iron-oxide-tinted mineral sunscreens win for that condition specifically.

3. Your serum has oxidized

L-ascorbic acid vitamin C turns from clear to amber to dark orange over 2–6 months. Once it's amber, it's already losing efficacy. Once it's brown, the oxidation product (dehydroascorbic acid) is actively pro-inflammatory — and on melanin-rich skin, every inflammation event can produce new PIH. You're applying a product that's giving you the problem you're trying to fix.

Fix: store vitamin C refrigerated, in a dark bottle, replace every 3 months. Or switch to stable derivatives (THD ascorbate, sodium ascorbyl phosphate) that don't oxidize. Full vitamin C guide.

4. You're stacking too many actives

Vitamin C + retinol + AHA + benzoyl peroxide + niacinamide all in the same week. Each one is "the active that's supposed to fade my spots." Together they irritate the barrier, and on Fitzpatrick V–VI, every micro-irritation produces fresh PIH. You're getting new spots faster than you're fading old ones.

Fix: introduce ONE active at a time. Use it for 4 weeks. Observe. Then add the next. Boring but it's the only protocol that doesn't backfire on melanin-rich skin.

5. The pigmentation is deeper than topicals can reach

Hyperpigmentation has two layers. Epidermal (the surface) responds to topicals. Dermal (the deeper layer) doesn't — vitamin C and niacinamide barely penetrate that far. If your dark spots are dermal melasma, ochronosis from years of hydroquinone misuse, or old PIH that's now lived in the dermis for 18+ months, surface-level products will plateau.

Fix: the deeper-acting actives (tranexamic acid, prescription tretinoin, low-energy fractional laser, microneedling with PRP) can reach the dermis. These usually require a dermatologist familiar with melanin-rich skin specifically.

6. You're giving up too early

Most people abandon a routine at week 6 because "nothing's happening." On melanin-rich skin, week 6 is when subtle changes begin. Visible fading usually starts at week 8–12. Meaningful change at week 16. Significant fading on established marks: month 6.

Fix: commit to 16 weeks before judging a routine. Photograph your skin in the same lighting once a week — your eye won't catch slow changes day-to-day, but week-12 vs week-1 photos will surprise you.

7. You're picking, rubbing, or over-cleansing

The fastest way to keep dark spots alive is to keep injuring the same spot. Friction from harsh cleansing tools, picking at bumps, aggressive exfoliation, even sleeping in the same position on rough sheets — any micro-trauma triggers fresh melanin production. On melanin-rich skin, the threshold is low.

Fix: press serums, don't rub. Cleanse with fingertips, not brushes. If you pick, get a hands-busy habit (knitting, fidget toy, anything) for the times you reach for your face.

The single highest-leverage fix

If you're going to fix one thing this week, fix #1 — diagnosis. Knowing whether you're treating PIH, PIE, melasma, or some combination changes which products belong in your routine. Everyone we've seen who struggled with stubborn dark spots for years was treating the wrong condition with the right products. Get the diagnosis right, the routine follows.
