You're concerned about how to store tanning peptides after opening? This is crucial, as these active ingredients are extremely sensitive to the environment and can easily become inactive or deteriorate if not handled carefully.
After opening, tanning peptide products should be sealed, protected from light, and stored in a dry, refrigerated environment at 2–8℃ to maximize the stability and activity of the peptide components. Specific storage requirements vary slightly depending on the dosage form. Here are detailed suggestions:
Topical skincare products (such as body lotions or serums containing myristoyl tetrapeptide-20)
Storage conditions: After opening, tighten the cap to avoid frequent contact with air. Store in a cool, dry place, ideally at 15–25℃. If the temperature or humidity is high in your area, it is recommended to refrigerate in the crisper drawer (2–8℃), but avoid freezing.
Protect from light and moisture: Keep away from windowsills, bathroom mirrors, and other areas exposed to direct sunlight or dampness to prevent ultraviolet rays and moisture from accelerating peptide chain degradation.
Usage Cycle: Follow the "opening icon" on the packaging, usually 6M or 12M, meaning it's best used within 6 to 12 months after opening.
Injectable or Implantable Dosage Forms (e.g., Alfanotide)
Strict Aseptic Management: Once opened, use immediately. Unused portions should not be stored for reuse and must be disposed of as medical waste.
Temporary Storage Before Use: If removed from refrigeration but not yet injected, leave at room temperature for no more than 2 hours, avoiding shaking or direct sunlight.
