I have Reign (deep metallic copper), King K (soft metallic gold) and Heir (golden metallic peach). Reign is my favorite of the three and the most pigmented. It's the only shade that can be worn alone. The other two shades need liner or lipstick underneath. If not, the metal texture just makes your lips look dry.
I love this brush! I use it with the Anastasia glow kits, Jeffree Star highlighters and with the Kat Von D highlighting shades in the contour kit. It picks up the powder so well. I've used other "highlighting brushes" and this one is far superior (Tarte dual ended highlighting brush, sigma brush).
This mask is supposed to be "calming." You're supposed to leave it on for 10 min. After 3 min, it started burning really badly. I took it off after immediately and my face continued to have a burning sensation.
