A cosmetic skin care product that includes an applicator and a skin care composition. The applicator includes a uni-directional magnetic array with a pitch of between 1.7 and 2.5 and a magnetic field strength of between about 24.0 and 36.0 mT. The skin care composition includes palmitoyl-lysine-threonine-threonine-lysine-serine and a dermatologically acceptable carrier. The magnetic array is tailored to enhance penetration of the Pal-KTTKS into skin during application of the skin care composition. The applicator may include a second magnetic array juxtaposed on a first magnetic array to form a bi-directional array that enhances penetration of the Pal-KTTKS into skin.
