The best thing I've found (and trust me, I've tried everything!) is Jessica Nails Critical Care.
Try and push your cuticles back, then apply the above using 10 strokes of the brush for each nail. Repeat every day (I usually do it every second day though!) for a week, then remove, do your cuticles and start again!
If you can be bothered, applying solar oil (another miracle product in my opinion!) over the Critical Care (at a different time in the day when the polish is dry) really helps my nails!
