Superdrug Sugar & Spice Self-Heating Mask RRP £0.99 (and usually on 3 for 2).
"Superdrug's Sugar & Spice Self-Heating Mask is brimming with all things nice! Relax and embrace the rich and comforting cinnamon and vanilla aromas, while the warming sensation helps to cleanse away impurities. Suitable for vegetarians and vegans."
After applying the mask the heat faded quite quickly, the mask doesn't dry, and in a way I like the masks that dry and tighten, and it was also quite difficult to remove and when you apply water to your face it feels very....slimy?
