PhiTo-Pep 1.6

Firm, smooth, and energize the skin with Circadia’s PhiTo-Pep 1.6. An advanced peptide complex that supports visible elasticity and renewal for a refined, youthful-looking complexion.

Progressive Benefits

With consistent use, the skin appears firmer, more resilient, and visibly refined. Fine lines and uneven texture are softened, and the complexion takes on a lifted, radiant look that reflects skin in balance and harmony.

Science-Backed Formula

Powered by Circadia’s proprietary PhiTo-Peptide Complex 1.6. A synergistic blend of Matrixyl™ 3000 (Palmitoyl Tetrapeptide-7 & Palmitoyl Oligopeptide), Argireline® (Acetyl Hexapeptide-8), and Snap-8™ (Acetyl Octapeptide-3) that work together to help refine the look of expression lines and support elasticity. Apple stem cells and Edelweiss stem cells reinforce resilience and antioxidant defense, while hyaluronic acid enhances hydration. Balanced at a pH of 5.5-6.0 for maximum skin compatibility and performance.
