Hi, I’m relatively new to diy (2 years or so now) and I’m very cautious. I enjoy trying products with low to no risk of vo of course so I was super excited to try this product. With any new product I inject small amounts in all areas I plan to fully treat after trial injections. I’ve injected small amount in my troubled areas (enough to make a small bubble) and thus far no adverse reactions. I will update my review after full treatment but for now I will add my video and photos of before and immediately after. After full treatment I’ll update for comparison for product effectiveness. Code Jessica10 saves me money every time.
