Description
Other risks include a hematoma where blood pools in or near the injection site

Temperature proves most critical - every 10C increase doubles degradation rate, meaning room temperature storage (25C) degrades peptides 4-8x faster than refrigeration (2-8C) and dramatically faster than freezing (-20C or below)

This rotation maximizes collagen stimulation from three different angles without ingredient conflicts
