Our take
Is Riboflavin (Vitamin B2) a Good Ingredient?
Good, because it's a reliable yellow colorant with good stability in water-based systems and a long history of safe cosmetic use at low levels. It's rated for what it does well, coloring products consistently, not for any skin performance benefit, since it doesn't offer one.
What it does
Skin Benefits
Gives products a bright golden tint that improves visual appeal, and helps maintain consistent shade across different batches of the same item.
Where you'll find it
Uses in Skincare & Cosmetics
Used as a colorant in gels, shampoos, lotions, and serums to achieve warm-toned formulas, and also appears in makeup and bath products for uniform coloration.
Before you use it
Low irritation potential at cosmetic concentrations and typically well tolerated, including around the face. As with any colorant, rare sensitivities can occur; discontinue use if irritation develops.
