Best Practices for Minimizing Reactions
Based on my personal experiences, here is how to navigate the use of peptide products safely:
1. Patch Testing: Always apply a small amount of the product to your inner forearm for 24–48 hours before applying it to your face.
2. Simplify: Avoid mixing multiple active serums. Start with one peptide product and monitor how your skin feels for at least two weeks.
