The proprietary peptides come with studies and reliable anecdotal evidence to verify their effectiveness as amongst the best anti-aging and anti-wrinkle actives available to date.

    Syn®-Tacks features a specific, patented combination of two well-research peptides that stimulate the rejuvenation of Laminin V, Collagens IV, VII and XVII, and Integrin β4, all at once, dramatically improving the performance of Dermal-Epidermal Junction (DEJ).
