켈리장
저는 예전에 쓰다가 그만 뒀어요 효과도 잘 모르겠고 따로 시간내서 할 시간적 여유도 없더라구요 피부관리도 정말 부지런해야 가능한것 같아요
I wasn't using one before, but I recently got one and have been using it, though I haven't noticed any significant effects yet.
If you search on YouTube, there are so many devices that seem complicated. Is there a device you have used that you felt was effective?
