Editorial Summary: Reddit users favor niacinamide for oil control, acne and brightening but report mixed reactions at higher concentrations; start low, patch test and avoid piling on actives. Lancôme Génifique is praised for radiance and texture but is expensive and can pill when layered. Vitamin C effectiveness depends on stable formulation and airtight packaging; tranexamic/azelaic acids and tretinoin are commonly recommended for stubborn pigmentation.
