Its a common misconception that Glow in the Dark products readily glow straight out of the packaging or tube. The level of glow will depend on how long it has been exposed to light and how thickly it has been applied to skin. We recommend charging under artificial light for best results. The Glow is a soft subtle glow, rather than an intense bright glow. This is due to the laws concerning these types of products and we have strict safety limits of how much of the phosphor ingredient we can use.
