I’ve actually had Lemon Bottle done professionally a few times. After losing a lot of weight, I still had that little double chin that I wanted to get rid of.
It’s not systemic — it’s injected directly into the fat layer of the specific area you want to treat, so it’s targeted rather than something you inject once and it works everywhere.
From my experience (and what I was told from the practitioner), you may need a course of treatments to see a noticeable difference. One session alone didn’t do much for me, but after multiple sessions spaced a few weeks apart, I started to see gradual changes. It’s definitely not an instant fix and results can be subtle, but it can help with stubborn pockets.
That said, results seem to vary a lot person to person.
