How to use
Use approximately 1-2 times a week. Use after toning your skin with lotion. Can be used either morning or night. 1: Hold the handle with your right hand and slowly unfold the mask. Be careful not to drip. 2: With the handle on the right hand, align the mask with your eyes and mouth and press it firmly against your skin. Then, while lightly pressing the notch under your chin, hold the cheek area and pull each side up towards your temples, overlapping the mask to ensure it adheres firmly. Leave the mask on for 10 minutes, then remove it and massage any remaining liquid into your skin with your palms.

I bought it as a trial! It's more affordable than Kosedeco! I think Kosedeco has a more immediate effect.
I think that just using this sheet mask once will leave your skin feeling refreshed. It's also great for skin that can't tolerate alcohol, so I keep it in stock.
I love the texture of the pack. I think it has improved my skin tone. It's a little pricey, but I'd like to buy it again.
Since sheet masks are left on the face for about 10 minutes, a pleasant scent is quite important, and I liked the scent of Melano Shot. I appreciated the manufacturer's thoughtfulness in the way the handle made it easy to distinguish between the left and right sides when removing and unfolding the mask. The numerous notches around the face line and the left and right areas of the eyes made it easy to layer the mask securely, and the exquisite shape even covered the eyelids. While not as cloudy as a serum, it had a firm consistency, adhered easily, and never peeled off. After leaving it on for a while and peeling it off, my skin felt radiant. Since the sheet mask remained well-absorbed even after use, I was able to apply it to dry areas like my arms and shins. While I don't plan on using it regularly, given the variety of affordable sheet masks available, I felt it was a good product to use while relaxing when I had the time.
It was a lotion-based pack that adhered well to the skin. It was a bit pricey, but I don't think you'll see results after just one use. It's hard for me to continue using it, so I won't be repurchasing it.
