sr-(Prolinyl Di sh-Polypeptide-145)

BJY-PeptaLift-4 is an anti-aging peptide ingredient composed of 17 amino acids. 

By inhibiting SNARE complex formation, it helps prevent the appearance of wrinkles associated with muscle contraction and 

supports improved skin elasticity.

› Improves Expression Wrinkles
Inhibits SNARE complex formation, helping prevent and improve the appearance of expression wrinkles caused by muscle contraction.

› Inhibits Muscle Contraction Signaling
At 10 ppm, BJY-PeptaLift-4 inhibited acetylcholine release by 34.31%, thereby reducing signaling associated with muscle contraction.

› Improves Skin Elasticity
Inhibited elastase activity by up to 35.8%, helping maintain skin elasticity.

› Promotes Collagen Production
Increased a Type I procollagen-related marker by up to 66.9%, helping support collagen production.

› Improves Eye-Area Wrinkles
In a 4-week human application study using an eye cream containing 100 ppm BJY-PeptaLift-4, eye-area wrinkles improved by 21.52%.
