Any harm? I did a noncross linked HA Mesotherapy procedure for a beginner. Hi, I used Celosome Aqua with a 32G 1.5 mm crystal3 pin needle. I researched that Celosome Aqua is safe effective. It is noncross linked HA and has mannitol, and is great for rejuvenation; it is a skin booster. The first time I did this procedure- the syringe was hard to push. After realizing I had to push harder, the product came out. However, I have a little bumps on my face. ( more on right side of face then left side). Am I safe. Is this normal. Will they go away?
