1. Vobella, 黑眼圈針 are all hyaluronic acid filler.
2. 黑眼圈針 got some extra ingredients inside such as vitamin and mineral which MAY be helpful for dark eye Circle
3. Actually all filler may help a bit for dark eye circle as it just covered the colour of the eye muscle after injection ( which is actually the cause for most cases of dark eye circle )
4. , 黑眼圈針 usu absorbs more water than Vobella which means some ppl got more swollen afterwards
