Matrixyl has remained the fashionable anti-ager's ingredient of choice for several seasons now. However, I recently came across something called Syn-tacks and I am asking myself if this could be the new black.

Like Matrixyl 3000, Syn-tacks is a combination of two synthetic peptides. In the case of Syn-tacks, these peptides are palmitoyl dipeptide-5 diaminobutyloyl hydroxytheronine and palmitoyl dipeptide-6 diaminohydroxybutyrate. According to the manufacturer of Syn-tacks, these two peptides interact with the most relevant protein structures of the dermal-epidermal junction and stimulates a broad spectrum of things responsible for youthful skin - laminin V, collagen types IV, VII and XVII and integrin - all at once.

For example, collagen IV activity is increased by 190%, according to the manufacturer. Tests have been carried out using a 1% concentration of Syn-tacks over 56 days and 84 days. After two months, skin tonicity was improved by 32%, anisotropy by 62% and cellular cohesion by 23%. Like the data for Matrixyl's results, this was conducted by the manufacturer and has not been independently corroborated.

Products with Syn-tacks remain relatively rare. Most notable, perhaps is Peter Thomas Roth's Unwrinkle Night ($110). This powerful-looking potion really hedges its bets; there are three types of neuropeptides (the ones that stop facial muscle movement) and five peptides in the form of Matrixyl 3000, Syn-tacks and Syn-Coll, which is palmitoyl tripeptide -3.

Alternatively, you can try a DIY version at Platinum Skin Care. They sell a bottle of Syn-tacks active for $24.95 that you can add to one of their base creams or a potion you have lying around at home. It contains: Deionized Water, Glycerine, Palmitoyl Dipeptide-5 Diaminobutyloyl Hydroxythreonine Palmitoyl Dipeptide-6 Diaminohydroxybutyrate, Gynostemma Pentaphylum, Panax Ginseng Root Extract, Ethoxydiglycol, Benzyl Alcohol ( BA is natural anti-microbial, not a drying or grain alcohol), Methylisothiazolinone (a preservative that seems, despite one study on rats, to be harmless).
