Ingredients Details
Caffeine
Common Name(s): Caffeine,methylxanthine anti-cellulite,antioxidant vasoactive
CAS Number: N/a
DESCRIPTION
What It Does: Stimulates lipolysis in adipocytes by inhibiting phosphodiesterase (preventing camp breakdown), reduces eye puffiness through vasoconstriction of periorbital capillaries, and provides antioxidant dna repair stimulation for photoprotective benefit.
Why It's Used: The only cosmetic active with a well-defined mechanism for anti-cellulite claims โ phosphodiesterase inhibition elevating adipocyte camp is the documented biochemical pathway, providing mechanism-based efficacy substantiation superior to most slimming actives.
How It Works: Caffeine inhibits phosphodiesterase (pde3, pde4) preventing camp hydrolysis โ elevated camp activates protein kinase a โ phosphorylates hormone-sensitive lipase โ lipolysis of triglycerides in adipocytes. for eye puffiness: caffeine's adenosine receptor antagonism reduces prostaglandin-mediated capillary dilation in periorbital tissue, reducing fluid accumulation.
