I have skin redness and though super delicate skin. I live in a really REALLY hot place. When I got the masks, I put them in the fridge to try them as soon as possible. After a day of a lot of sun and temperatures of 40°C, I got home at night, did my nighttime routine and I could see the redness on my cheekbones. I put the mask sheet on and felt immediate relief. After removing it the redness of my face was almost gone and I felt my skin more relaxed. I TOTALLY recommend them!!!
