4. Core Biological Mechanism & Efficacy
-
Boost Keratin Synthesis for Eyelash & Eyebrow Growth
Activates keratin gene expression in hair matrix cells, accelerates keratin production, lengthens eyelash growth cycle, increases lash density, thickness and length; core raw material for eyelash serums.
-
Anti-Wrinkle Signal Peptide (Relax Muscle Contraction)
Competitively blocks endothelin signal pathway, reduces excessive contraction of dermal muscle cells, smooths crow’s feet, forehead fine lines and static wrinkles, known as mild "topical botox peptide".
-
Promote Collagen & Fibronectin Secretion
Stimulates fibroblast activity, upregulates type I collagen synthesis, enhances skin elasticity, relieves sagging and photoaging dullness.
-
Strengthen Skin Barrier & Anti-Oxidation
Improves epidermal keratinocyte arrangement, reduces transepidermal water loss; scavenges ROS free radicals to alleviate UV oxidative damage.
-
Scalp Nourishment & Anti-Hair Loss Auxiliary
Improves scalp microenvironment, nourishes hair follicles, reduces brittle hair and shedding when compounded with biotinoyl tripeptide-1.
