Brand: Dr. Diamond's Metacine

This advanced lip treatment, developed by renowned Beverly Hills facial plastic surgeon Dr. Jason B. Diamond, M.D., F.A.C.S., is a more sophisticated approach to a lip plumper. The silky, weightless, and non-sticky bioserum is engineered to address the biological changes behind visible lip aging—caused by declining collagen and hyaluronic acid and a loss of supportive adipose tissue and barrier lipids—which can leave lips and the vermilion border looking thinner, drier, and less pert.

At the center of the formula is the line’s proprietary Hyaluron Peptide-6 BioFill, a topical, volumizing complex combining six biomimetic peptides with hyaluronic acid oil and poly-hyaluronic filling spheres. It works alongside targeted botanical extracts to immediately improve fullness, firmness, contour, hydration, and address any signs of premature aging on and around the lips.

INSIDE THE FORMULA

• Hyaluron Peptide-6 BioFill: A hero complex designed to support collagen, hyaluronic acid, and adipose tissue synthesis while providing immediate and sustained hydration
• Bioidentical Skin Lipids: A restorative blend of ceramides, essential fatty acids, shea butter, and plant lipids helps replenish the delicate lip barrier and improve moisture retention
• Undaria Pinnatifidia Extract: A targeted botanical extract that helps sharpen the appearance of lip contour and fullness while enhancing the lips’ natural color
• Zanthoxylum bungeanum fruit extract: Helps visibly smooth lip lines while soothing irritation and sensitivity
