Science
Mechanism of Action
TAPS functions by stimulating the in vivo production of glucosylceramide, a crucial precursor that leads to an overall increase in ceramide content within the skin. This action directly strengthens the epidermal barrier, reducing transdermal water loss and providing deep moisturization and repair. Beyond barrier support, TAPS exhibits potent anti-inflammatory properties, inhibits angiogenesis to minimize the appearance of dark circles, and actively promotes skin cell regeneration. It further contributes to anti-aging by boosting the synthesis of collagen and elastic fibers. Additionally, TAPS provides antioxidant defense, inhibits melanin production for a brighter complexion, and possesses antibacterial activity against common skin pathogens like *Staphylococcus aureus* and *Propionibacterium acnes*, thereby reinforcing the skin's intrinsic protective system.
