Tried it 3 times. Once with 4 syringes
HA, twice with 2 syringes
HA each time. Spaced about 4 months apart. Can definitely say it's not worth it for me. Results are subtle, barely noticeable to me, so that means likely not noticeable at all to anyone else. Despite really wanting it to be great, its just not. Unless you have unlimited money I think you'd be much better off focusing on something that gives better results. On the plus side I didn't have any bad reactions, lumpiness, or anything like that; just a lighter wallet.
