용량이커서 오래 쓰겠어요
The essence I've been using lately is a collagen serum.
It is a product sold only at hospitals or specialized clinics.
It has a slightly runny texture and applies smoothly.
You can take care of yourself at home without going to a professional salon.
It has a large capacity, so you can use it for a long time.
