I have always used acrylic nail extensions in the past but recently I started using these new bio gel nails. I think they are far better. They seem to last longer and feel more natural, almost like the real thing. Bio gel nails are supposed to promote natural growth hence the name “bio”. I’m not sure why acrylic extensions wouldn’t allow this come to think of it. The other thing I like about them is the fact that there is very little smell from the mixture when being applied. The smell from the acrylic paste is really horibble. I was wondering what anyone else thought?
