Can Tranexamic Acid be applied directly to the body?

Tranexamic Acid powder should not be applied directly to the skin, including on the body like arms and legs. It is an active ingredient that needs to be properly formulated into a cosmetic product such as a cream, lotion, serum, or gel.

Applying pure Tranexamic Acid directly can cause skin irritation.

According to regulations, Tranexamic Acid can be used in cosmetic formulations at a maximum concentration of 3% for skin brightening purposes. If used at higher concentrations (historically above 5%, currently above 3% for cosmetic registration), it must be registered as a medicine.

Products like Tranexamic Acid (Trans-White™) are ingredients meant for formulation, not direct application. Nano-TXA™ (Tranexamic Acid Nano Emulsion, Penetration Base) is a formulated base containing Tranexamic Acid designed for enhanced skin penetration when mixed with other water-soluble actives, but it is also not intended for direct application of the pure ingredient powder.

Always use Tranexamic Acid as part of a finished cosmetic product at the recommended concentration.
