This is a 7-pack sample of Beauty Opener, which is currently discontinued. Although it is a new, unused item, it has been stored at home. You can use it for your morning and evening skincare routine. After washing your face, take an appropriate amount (1-3 drops) in your hand and gently apply it to your skin. Apply more to areas of concern. Afterwards, prepare your skin with lotion, cream, etc. It contains a 90% concentration of eggshell membrane, which is deeply involved in the production of type I collagen, which decreases with age. By using it on clean skin after washing your face, it penetrates directly into areas of concern. Please check the profile before commenting or purchasing m(_ _)m
