- Axxium is a soak off gel product used for nail enhancemnts
- Gel Color is a gel polish.....OPIs version like Gelish, Gelicure, Artistic...etc
- Axxium since it is a soak off product, then yes it is porous as is Gel Color
- You can use solar oil on cuticles and surrounding skin...that's never a waste
- Axxium you can do nail fills like any enhancement
- Gel Color you would soak off after 2 weeks and reapply
- Axxium is a stronger product better suited to weaker nail
- Gel Color would be better suited to heathier nails
I think that got most of your questions
