This improvement occurs because increased collagen production helps fill in fine lines and wrinkles from within the skin layers, rather than just temporarily plumping the surface
If it does not dissolve after 5 minutes of gentle swirling, possible causes include: degraded peptide (check storage history and expiration status ), contaminated water (use a fresh vial of bacteriostatic water), or water temperature (cold water from the refrigerator dissolves peptides more slowly than room temperature water)
