No matter what filler you get, if you get more than 1cc on one side, you absolutely must know that the original plump shape will not be maintained due to the force of gravity and will flow down... Even so, you need to get at least 1.5cc to get the shape... After getting filler, if it's your own face and you have to wait about 2 months , you absolutely have to dissolve it and get another injection... Or you'll get another injection on top of the previous area and it'll go down again and get another injection... This isn't a side effect of filler, but since I have no knowledge and am ignorant, the director will take care of it for me~~! This kind of mindset is doomed..... Absolutely, absolutely... Let's melt it down and get it again... Absolutely.... And definitely get hyaluronic acid... There weren't many reviews for Perfecta... I got it... It didn't even contain a small amount of anesthesia, so it really hurt a lot...... <><><<< I was really annoyed by Perfecta, because my face looked swollen for about a month... Ha... This is a side effect. It started to drip like other people's... I was like this, but after about 2 weeks, the swelling went down and the Perfecta filler was absorbed to a certain amount, so I was satisfied ㅋㅋㅋㅋㅋ Next time, instead of getting Perfecta, I'd get the more expensive Respilene,,, but Perfecta filler is very cost-effective because it's an imported product... But it's hard when I press on it a little and it hurts sometimes, so I'm worried. If there are any side effects, I should go and get it melted right away >>>
