Storage and Stability of Cosmetic Lyophilized Peptides

Storage guidance must be product-specific. In general, cosmetic lyophilized peptide powders require a sealed, dry and controlled environment that limits moisture uptake, heat exposure and unnecessary opening.

Storage Control Points

• Keep the package sealed until use
• Protect from humidity and direct light
• Follow the supplied product-specific temperature guidance
• Allow appropriate equilibration before opening when needed
• Record receipt and storage conditions
• Use a defined inventory rotation system

Shelf Life Is Evidence-Based

A shelf-life statement should connect to the material, package, storage condition and supporting stability data. After the powder enters a cosmetic base, a new finished-product stability program is required.
