For your skin
Sometimes called "topical Botox," it's a peptide that subtly reduces the depth of expression lines around the eyes and forehead when used daily over months. Mild effect, but real.

Hexapeptide that mimics the N-terminus of SNAP-25, competitively interfering with SNARE complex assembly and reducing neurotransmitter release at neuromuscular junctions in superficial expression muscles.
Why we tier this moderate
6 cited papers across 4 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
