Retinol works through the retinoid receptor pathway (RAR/RXR), directly upregulating specific procollagen genes and inhibiting matrix metalloproteinases (MMPs) that break down existing collagen [6]

The reason stacking raises safety questions is simple: when you combine signals, you can also combine side effects, sensitivities, and unintended downstream effects

In the AMY 1 R and AMY 3 R Y37 rAmy interacts with residues in the respective RAMP and the CTR ECD, however the small side chain of P37 Cagri is completely buried by the surrounding CTR ECD residues, forming extensive hydrophobic contacts with W79 ECD and no direct interactions with either RAMP1 (AMY 1 R) or RAMP3 (AMY 3 R), again consistent with the restrictive interactions formed by Pro32 sCT with the CTR ECD

Yes, peptides can generally be used with retinol in skincare routines
