This is an AGE-R beauty device equipped with an air shot function! I am selling it because I no longer have the opportunity to use it. The power turns on, so I believe it works without any problems. - Model Name: AGE-R - Included: User manual, charging cable Functions: This is a home beauty device that utilizes the principle of a derma pen, creating tiny holes on the skin's surface to promote exfoliation and improve pores. Effects: It can be expected to improve the penetration of skincare products, reduce pore size, improve skin texture, and exfoliate. How to use: Use on dry skin after washing your face, holding the probe head slightly away from the skin and gliding it across your entire face. It is recommended to use it 1-2 times a week. There are some old marks, but there are no noticeable scratches. Thank you for your understanding that this is a used item. (Operation has been confirmed) Thank you.
