Basic Red 1:1

Basic Red 1:1, also known as Rhodamine 6G, is a synthetic fluorescent dye belonging to the xanthene dye family. It is commonly used in textile dyeing, research applications, and as a tracer compound in scientific studies due to its bright fluorescence and stability.In skincare formulations, this ingredient is not typically used for direct skin benefits. Its presence in skincare products is rare and usually limited to research contexts or specific diagnostic applications where its fluorescent properties are intentionally utilised to track delivery or penetration of other active ingredients.

Basic Red 1:1 fluoresces under ultraviolet light, emitting a bright red-orange colour. This property makes it valuable in research settings where scientists need to track the movement and distribution of formulated products through skin tissue layers. The dye itself does not alter skin function; rather, it serves as a visible marker to study how other active ingredients behave when applied to skin.

This ingredient is not intended for consumer use as a standalone skincare product. If encountered in a skincare formulation, it is likely present in minimal concentrations for research or quality-control purposes and would not require specific usage instructions.

Limited safety data exists for Basic Red 1:1 in topical skincare formulations. Toxicological studies in other contexts suggest potential concerns at high systemic doses, though topical application at cosmetic concentrations has not been extensively evaluated. Consult product labelling and contact the manufacturer if you have concerns.
