Shared Safety Flags

2x 2 compounds share the teratogenic safety flag (GHK-Cu, Tretinoin). Monitor accordingly.
++
GHK-Cu + Tretinoin
Synergistic

Highly complementary combination for skin rejuvenation. GHK-Cu stimulates collagen synthesis, wound healing, and antioxidant enzyme production through copper-dependent pathways, while tretinoin drives collagen production via retinoic acid receptor activation. Together they target skin aging through distinct and additive mechanisms. Apply GHK-Cu serum and tretinoin at the same time in the evening routine, or use GHK-Cu in the morning.
