💡 Pro tip for salons

When a client comes back with a complaint, note on which fingers and where the gel is lifting. Lifting always on the same nails points to the nail plate (e.g. oily or very flexible nails), lifting at the cuticle points to the prep, and lifting at the tip points to missing capping or a stress area that is too thin. This helps you find the cause faster and take targeted action.

FAQ: Common questions about gel problems

Why is my gel lifting after just a few days?

In most cases the prep is the cause: cuticle residue on the nail plate, shine that was not removed or oil on the natural nail. Nail prep and a suitable primer improve adhesion considerably.

Is the sticky layer after curing a mistake?

No. Many gels form an inhibition layer, which even helps the next layer adhere when building up. After the final step you remove it with cleaner – or you use a finish gel without a sticky layer.

Is it normal to feel heat under the lamp?

A feeling of warmth is normal, because curing releases reaction heat. If it gets uncomfortably hot, take your hand out briefly and work with thinner layers in future.

Can I simply soak off builder gel?

Classic builder gels cannot be soaked off; they are filed or drilled off. Soaking works for shellac, UV polishes and soak-off products.

What should I do if my skin turns red or itches after gel nails?

Stop the treatment and have the symptoms checked by a doctor. For future sets: no skin contact with uncured gel, don't overload the brush and choose HEMA-free products.
