Peptide-rich plasma and theanine
Work well together
Use them together in the same routine, applying theanine first and peptide-rich plasma right after to boost hydration. Theanine helps peptides work better by balancing skin moisture and giving cells a supportive boost. If your skin feels sensitive, you can apply them on alternate nights or wait a few minutes between steps.
