Restylane Skinbooster risk of allergic reaction?

Hi there, I am currently living in Europe and Restylane Skinbooster was recommended to improve skin hydration. I am worried about allergic reactions and other side effects. I found studies that indicate risks for hyaluronicacid fillers but (if I understand it correctly) skin booster is not a filler so maybe the risk of complications is different? I would appreciate if someone could point me into the right direction to get more information about the associated risks. Thanks a lot in advance!
