Tingle products deliver a warming, reddening effect on the skin. Tingle products increase the skin cell’s microcirculation and oxygenation to produce deep, dark tanning results. Tingles are for your advanced tanners and are not recommend for beginning tanners or individuals with sensitive skin. Tingle products are also affective on hard-to-tan areas such as women’s legs. As with all tigle products, extra care should be taken when hanling children and pets as the reddening effect could be transferred to skin even hours after use
