Challengel Builder Gel for nails – hard, HEMA-free, ideal for nail extensions

 Challengel is a hard builder gel developed for those who want to combine fast work with strong and long-lasting results. Perfect for nail extensions with forms, strengthening the natural nail plate, and for the no-file technique.

 Thanks to its light consistency, the gel doesn't pull on the brush during application, smooths out quickly and evenly, and thus minimizes filing. Its high hardness allows for pinching a stable tunnel that won't stretch while worn. The style lasts up to 5 weeks.

 The formula is free of TPO and HEMA, which reduces the risk of irritation and makes the product more suitable for sensitive skin.
