The description mentions a subtle glow — does that mean shimmer particles, and will it transfer onto clothing?

The "subtle glow" described is typically achieved with finely milled pearlescent pigments or optical diffusers blended into the emulsion, not coarse glitter. These particles sit on the skin surface and catch light to make limbs look smoother and more even in daylight. Because the lotion is designed to absorb quickly, the carrier fluids evaporate and the emollients penetrate, leaving the pigments adhered to the stratum corneum rather than sitting wet on top. In practice, wait 2–3 minutes after application before putting on fabric; a light pat with a towel can remove any excess. Dark clothing is unlikely to show marks, but if you're wearing something sheer or silk, give it an extra minute. The effect washes off with normal showering and does not build up on skin over time.
