Every use for Tend Skin was discovered accidentally by product users who experimented to see if Tend Skin would work on their problem. Some discoveries happened without trying to solve a problem, such as Tend Skin’s ability to harden fingernails. This effect was discovered by Michelle who fills the sample bottles. She noticed her fingernails getting rock-hard after filling samples bottles for a while (she spills a little!). Laser Hair Removal: We are hearing that Tend Skin can be used very effectively after laser hair removal. It Is reported by users to clear redness in 15-20 minutes as with waxing/electrolysis as well as to minimized next-day “bumping”. Unlike waxing or electrolysis use, DO NOT use Tend Skin prior to Laser Hair Removal. It may prevent the laser from reaching into the follicle and may interfere with fluids used on the skin in conjunction with the procedure.
