While Rachel didn't confirm the mask brand, it does appear to be the Tony Moloy Kiss Kiss Lovely Lip Patch, which contains ingredients including Glycerin, Chondrus Chrisus and Witch Hazel.
Kim Kardashian and Jessica Alba are also big fans of the lip patches.
Jessica told Elle she became a fan when "A friend of mine from work brought this lip mask in and I put it on. They were really happy I wasn’t talking for 20 minutes!"
Rachel's other makeup staples appeared to include a generous serving of Nars and Chanel products, and one or two vibrant Beauty Blenders.
