Your dark spots aren’t one thing. That’s why nothing’s working.

A 50-page brand-neutral guide that decodes 12 Korean actives across PIH, melasma, sun spots, and post-procedure marks — with $/$$/$$$ product picks for Fitzpatrick III–VI skin. No affiliate links. No fluff.

What’s Inside:

• The 4 Types of Hyperpigmentation — a self-diagnosis flowchart so you stop treating melasma like it’s acne PIH.

• The Active Ingredient Atlas — 12 deep-dives on niacinamide, vitamin C (and which form), alpha-arbutin, tranexamic acid, azelaic acid, licorice root, kojic acid, mandelic acid, green tangerine, galactomyces, centella, and retinal. Effective concentrations. Timelines. Cautions for darker skin.

• The Layering & Conflict Map — the visual chart that finally answers “can I use vitamin C and niacinamide together?” Plus the 6 combinations that are actively making your spots worse.

• 4 Complete Routines — step-by-step AM and PM routines for PIH, melasma, sun spots, and barrier-compromised skin. Real product names at $/$$/$$$ tiers.

• The Sunscreen Section — why iron oxides matter for melasma, and the Korean SPFs that don’t leave a white cast on darker skin.

• The 90-Day Tracker — a printable so you stop wondering if it’s working and start seeing it.
