Has Anybody Had Lemon Bottle/Fat Dissolving Injections For A Double Chin?

Dunno if this is the right group, but has anybody had lemon bottle or fat dissolving injections done for a double chin and what did you think of the results? Also how many sessions did you have to have done. Im thinking of booking in for a consultation before I decide. I’ve seen people buying like DIY stuff and doing it themselves, but seems dodgy. I wouldn’t trust myself to not mess it up. thank you
