Vivier Gold Standard C E Peptides Duo

Brighten by day, renew by night.

This duo covers both halves of a great anti-aging routine. In the morning, vitamin C protects and brightens. At night, a high-strength retinol renews skin while you sleep. Two of the hardest-working ingredients in skincare, paired the way they are meant to be used.

What is in the kit

• C E Peptides. Vivier's gold-standard vitamin C serum, with pharmaceutical-grade vitamin C, vitamin E, and three peptides that brighten, firm, and defend against daily damage.
• Retinol 1%. A high-strength nighttime retinol that speeds cell renewal to smooth fine lines, refine texture, and keep skin even.

Why it is worth it
Buying the AM and PM workhorses together is the efficient way to build a complete anti-aging routine, and these two are designed to complement each other across the full day and night cycle.

How it compares
C E Peptides on its own is the daily brightener. This duo adds the renewal power of a strong retinol for anyone ready to commit. GrenzCine Serum is the alternative if you prefer one maximum-strength serum over a two-step system.

Best for: anyone ready for a full AM and PM anti-aging routine and comfortable with a strong retinol.
Not ideal for: very sensitive skin or those new to retinol.

How to use
In the morning, apply C E Peptides to clean, dry skin, then moisturizer and sunscreen. At night, apply Retinol 1% to clean, dry skin, starting two to three nights a week and building up. Do not use both at the same time of day, and wear sunscreen daily, since retinol increases sun sensitivity.
