I bought this product to take care of my skin since the weather is getting drier! I've been using it for about a week now… I understand what it means to have a sheet mask that lifts your skint! I use it in the morning and evening. The swelling on my face has decreased and my skin has become very smooth. Above all, my skin became a lot more elastic, which really helped my makeup stick to my skin. It's seriously the best!! You can cool the Cooling Therapy Derma Stone in the morning and then apply the sheet mask and massage your skin to double the effect! You have got to try it!
