Derma Glow Serum FAQ
Derma Glow peptide serum, formulated with GHK-Cu and SNAP-8 for anti-aging benefits, has an estimated shelf life that varies based on storage conditions. In a dark room at room temperature (around 68-77°F / 20-25°C), away from light and heat, it can last 3-6 months, with optimal freshness maintained through its natural preservatives. Refrigerated (35-45°F / 2-7°C), it extends to 12-18 months unopened, as the cooler temperature slows degradation of the peptides and prevents microbial growth. Once opened, use within 3-6 months regardless, and discard if color, smell, or texture changes. Always store in refrigerated to maximize longevity.
