Science
Mechanism of Action
This ingredient functions as a powerful scavenger of diverse Reactive Oxygen Species (ROS), including superoxide anions, hydrogen peroxide, and hydroxyl radicals, along with electrophilic species like toxic aldehydes. Under oxidative stress, it is capable of releasing taurine directly within the skin. As Oxothiazolidinecarboxylic Acid, it serves as a pro-drug for cysteine, a critical precursor for the synthesis of glutathione (GSH), a key endogenous antioxidant. Its action extends to inhibiting tyrosinase, which effectively reduces melanin synthesis for brighter skin. Additionally, it promotes epidermal renewal by softening the cuticle, stimulating cell regeneration, accelerating keratinocyte stratification, and facilitating the degradation of corneodesmosomes to encourage natural desquamation.

Key findings
- 01 At concentrations ranging from 1% to 10%, Oxothiazolidine is readily absorbed by the skin and demonstrates excellent compatibility. Clinical observations indicate its efficacy in protecting skin against alterations induced by both infrared (IR) and ultraviolet (UV) radiation, controlling accelerated skin aging processes, and preserving the structural integrity of the epidermis, dermis, and dermal-epidermal junction (DEJ). It also provides immediate oxidative protection.
