Christel Nail Hardener: OZN’s plant-based nail hardener with calcium ensures naturally beautiful, strong nails and restores their missing elasticity.
After a short time, the nails become noticeably harder, more resilient, and are thus protected against cracking and splitting.
The best results are achieved with a 2-3 week treatment; apply the nail hardener every 2 days, wiping off the old layer with nail polish remover beforehand.
The ingredients used for OZN Carla are 90% sourced from sustainably grown, plant-based raw materials. All OZN products are 100% vegan.
Application
- File the fingernails into the desired shape and degrease the nails so the polish can adhere optimally.
- Do not use hand cream or other care products before applying polish.
- Apply the nail hardener to the natural nail and let it dry.
- Can be used as a base coat (make sure the nail hardener is completely dry before applying color polish) or alone for a beautiful, glossy finish.
- The best results are achieved with a 2-3 week treatment; apply the nail hardener every 2 days, wiping off the old layer with nail polish remover beforehand.
- Have a lovely day! Nina
