I'm looking into shoulder fillers because I'm so envious of people with square shoulders, but reading posts about side effects has suddenly scared me haha. I've heard that lumps or unevenness can occur, and I've seen reviews saying it's uncomfortable when moving the arms, so I'm hesitating. I especially paused a bit after seeing a post about asymmetry developing over time as a side effect. Still, those who had a successful outcome seem to be extremely satisfied. If anyone has actually had this done, please share your honest reviews regarding pain, duration, and whether you experienced any side effects.
