Kojic Acid in short
Derived from fungi used in rice wine and soy sauce production, kojic acid blocks the enzyme that makes melanin. It is effective on dark spots but can cause contact sensitivity in some people.
Tretinoin in short
The prescription-strength retinoid, and the gold standard for acne and photo-ageing, with decades of evidence. It works directly (no conversion needed), so it is stronger and more irritating than retinol or retinal.
