A STRONG BUY. We used Cocokind’s Resurfacing Overnight Sleep Mask for five months, 1-2x a week and found that it was like a gentle peel — you can definitely feel like working (tingling a bit) on your skin but much gentler than a retinol product that our skin could never really handle. The next day my skin was definitely peeling a little bit and much brighter/smoother without any irritation. We love that the ingredients are relatively clean, but while scent can be a bit odd, we were OK with it. All in all, we love the results for our skin and we LOVE the affordable price point.
