Best Serum for Fine Lines: How to Choose a Smoothing Active

The best serum for fine lines depends on the kind of line you are trying to soften. Expression lines usually call for a smoothing peptide, while lines linked to dehydration or loss of bounce may need hydration or firming support.

Expression lines

Start with Argireline if the lines show where your face moves most: forehead, brows, and crow's feet. SYN-AKE and SNAP-8 are also smoothing peptides with a similar cosmetic role.
