🌸 PDRN + GHK-Cu routine · the K-beauty glass-skin protocol
this is what i run when i'm NOT in a heavy stack period. it's the maintenance protocol · PDRN + GHK-Cu, alternating nights, topical for both. cheap, low-friction, sustainable. the routine i recommend to friends who want glow but don't want to subq 🎀
the schedule
odd nights (mon/wed/fri) · GHK-Cu 0.5% topical mixed into ceramide cream.
even nights (tue/thu/sat) · PDRN 2mg topical in HA serum.
sun · rest night · just gentle cleanser + moisturizer.
why alternate vs combine
PDRN + GHK-Cu in the same syringe / same product reduces the bioavailability of both. the peptides interact with the carrier matrix differently.
alternating gives each one a clean night of receptor binding.
isolates ur signal too · if one stops working u know which.
quick answers
can i layer them in the same routine?
yes but with 20 min between. PDRN serum → wait 20 min → GHK-Cu cream on top. but alternating works better in practice.
what's the daytime routine?
SPF + antioxidant (vitamin C). nothing peptide-side. peptides at night because that's when fibroblast activity peaks.
