Sabrina Elba's Beauty Must Haves, From Her Okra Serum to a $10 Body Oil

Elba is also a proud member of the LED mask fan club, with The Light Salon's Boost LED Mask ($495) as a staple in her routine. The portable mask delivers nearly the same results as a professional treatment, thanks to its two wavelengths: red (633nm) and near-infrared (830nm). With regular 10-minute treatments, you can achieve a youthful glow — any time, any place. "I know people are tricky with lights, but it's because you need consistency, and red light has so many proven health benefits. So I definitely splurge on a good red light."
