[Skin Improvement] I used Potenza + Juve Look together...isn't it supposed to be this effective at first??

I paid 1,150,000 won for 3 sessions of Potenza + Juvelook treatment in Gangnam. I expected some dramatic results after the first treatment based on the reviews I saw on the Internet, but even today, the 4th day, I actually don't know what has changed... Today, I consulted a plastic surgeon for another surgery. I went there and heard again, ‘The patient has very dry skin~ blah~~’ ㅠㅠ Is it normal for the first treatment to not be very effective???
