FLUORESCENT BRIGHTENER 393

Description

Fluorescent Brightener 393, also known as Disodium Distyrylbiphenyl Disulfonate, is a synthetic optical brightener widely used in skincare and cosmetic formulations. This water-soluble compound belongs to the stilbene family and is characterized by its ability to absorb ultraviolet light and emit visible blue light, creating a brightening effect on the skin.

The ingredient functions by adhering to the skin's surface, where it interacts with light to reduce the appearance of dullness and yellowing. It effectively masks minor imperfections and imparts a subtle luminosity to the complexion. Fluorescent Brightener 393 is particularly valued for its stability in various formulations and its compatibility with a wide range of other cosmetic ingredients.

In skincare products, it is typically used at concentrations between 0.01% to 0.1%. While it provides immediate visual benefits, it does not alter the skin's natural pigmentation or offer long-term brightening effects. Safety assessments have shown it to be non-irritating and well-tolerated by most skin types when used as directed. However, individuals with sensitive skin should perform patch tests before regular use. The ingredient is biodegradable and has a low environmental impact when released into water systems.
