Staying true to its science-backed heritage, Kiehl’s Since 1851 introduces its 1CC CollaShot Plump Serum – procedure inspired innovation! The patent-pending formula targets visible signs of aging due to collagen loss such as wrinkles, loss of elasticity, and lack of firmness, including after GLP-1-related weight loss.

Cheeks are the #1 facial area impacted by plumpness loss, often the first to appear deflated or less sculpted over time. While collagen production naturally declines with age, lifestyle factors such as UV damage, smoking, and stress can also contribute to visible changes in skin firmness and facial contours.
“Collagen is the main structural protein in the dermis and plays a critical role in maintaining skin firmness, elasticity, and support in the cheeks,” says Dr. Jane Yoo, a dual board-certified dermatologist and Mohs surgeon and Kiehl’s brand partner. “As collagen production declines over time, skin can become thinner, less resilient, and more prone to visible sagging.”
1CC CollaShot Plump Serum, formulated with supra-liposomal recombinant collagen polypeptides, is engineered for deep penetration 10 skin surface layers down. The formula also includes vitamin B12, which gives the serum its natural pink color, and Rhamnose.
Kiehl’s Formula’s Key Ingredients
- Recombinant Collagen Polypeptides: Biosynthetic collagen polypeptides similar to protein fragments found in human collagen
- Vitamin B12: Vegan colorant that provides pink color to the formula
- Rhamnose: Helps reduce visible signs of aging due to collagen loss
In addition, the serum provides 3x skin plumpness improvement, and +22% cheek-sagging improvement in GLP-1 users.
Fast absorbing and suitable for twice-daily use, 1CC CollaShot Plump Serum is a clinically tested power plumping formula designed to visibly firm and improve the feel of skin elasticity. The serum is available for $55 – $78 (30mL, 50mL) at Kiehl’s stores, Kiehl’s retailers and on Kiehls.com.
