Red 33

What Red 33 is & what it does

Red 33 is a synthetic dye used to impart a pink to bluish-red color to cosmetics, oral care, and personal care products. In a skincare or sunscreen formula it serves a cosmetic purpose, contributing to the product's color rather than its performance on skin. It is a certified color additive regulated for specific uses in cosmetic products.

Is Red 33 safe?

Red 33 is a certified color additive permitted for specific cosmetic uses and is added at the small levels needed for color. Some people choose to avoid synthetic dyes, and occasionally a dye may cause sensitivity in reactive skin. Dye-free products are an alternative if you prefer to avoid colorants.

What does Red 33 do in skincare?

Red 33 is a colorant whose role is entirely cosmetic. It gives a product a pink to red shade and does not change how the formula works on the skin. It is included for the product's appearance rather than for any active effect.

Is Red 33 natural or synthetic?

Red 33 is synthetic. It is a man-made dye produced through chemical synthesis, not extracted from a natural source. It is made to a regulated purity for use as a certified cosmetic colorant.
