- Signal peptides (like Matrixyl, Syn-Coll):
- Best compatibility with retinol
- Work synergistically
- Can apply together or separately
- Neurotransmitter peptides (like Argireline, Leuphasyl):
- Good compatibility but better separated
- Different pH requirements may interfere
- Apply separately (AM vs PM) for best results
