I paid for it myself

SNP Gold Collagen Ampoule Mask Pack

It is great because it provides intensive nourishment to dry and inelastic skin. It is said to contain collagen and gold to enhance nutrient absorption.

If you apply a nourishing mask in the evening, remove it, and then lightly apply essence and nourishing cream, your face will turn bright and elastic the next day. Especially in the summer, it is really great to keep it in the refrigerator before using it for a refreshing coolness.
