Retinol sensitivity. The purge. The peeling. There's a reason an entire generation of Swiss dermatologists moved on. Syn-Coll (Palmitoyl Tripeptide-5) is a clinically tested peptide that works differently — stimulating collagen synthesis without the inflammatory response retinol triggers. In ingredient testing by dsm-firmenich, it demonstrated 12% visible wrinkle improvement in 84 days. SÉRÈNE Suisse Elixir Gold & Caviar Serum. Swiss-formulated. Board-certified dermatologist verified. 30-day guarantee.
