| What it is | Sold, endlessly, as 'topical Botox' — a comparison the evidence does not support. Acetyl hexapeptide-8 is studied for softening the appearance of expression lines, and the studies that exist are small and mostly manufacturer-linked. Something may be happening. It is not in the same category as an injectable, and marketing that says otherwise is selling you a mood. | Rarely appears alone — it is half of the pairing most brands mean when they print 'Matrixyl 3000' on a box. As with its partner, the claim is signalling: a small peptide fragment that skin reads as a cue. Take the marketing about rebuilding structure as a description of appearance over months, not of biology you can verify at home. |
