When gel nails lift or Shellac chips after just a few days, the cause is almost always a mistake in preparation or application – and hardly ever "bad product". In this guide you'll learn why gel nail lifting happens, how to spot the cause and which steps will make your gel or UV polish hold reliably again.

What does "lifting" mean for gel nails and Shellac?

Lifting describes the product coming away from the natural nail – usually starting at the cuticle, the sidewalls or the free edge. At first you only see a small light patch or a gap where water and dirt collect. If you ignore it, the product lifts further, catches on hair or jumpers and finally breaks off.

• Gel nails: often lift at the cuticle area or along the sides.
• Shellac / UV polish: tends to chip at the tip or peel off in sheets.

Important: never pull or peel off a lifted piece – it takes top layers of the natural nail with it. Instead, carefully shorten and smooth the area and refill it, or remove the product properly.

The most common causes: why gel nails and Shellac don't last

1. Insufficient preparation

A shiny nail plate offers hardly any grip. The natural shine needs to be gently removed, for example with a fine BNC Buffer white 100/100. Just as important: the invisible cuticle that sticks to the nail plate must be pushed back and removed completely.

2. Oil and moisture on the nail

Skin oils, hand cream, cuticle oil or leftover moisture after washing your hands act like a separating layer. That's why a dehydrator such as BNC Nail-Prep goes on the nail right before application: it removes excess moisture and natural oils and air-dries in about 30 seconds. After that, don't touch the nail with your fingers.

3. Product touching the cuticle or sidewalls

Even a paper-thin rim of gel on the skin is enough: the skin grows and moves, the product lifts – and that's exactly where lifting starts. Always leave a fine gap to the cuticle and sidewalls and correct any excess with a brush or orange stick before curing.

4. Layers that are too thick

Thick layers often don't cure all the way through and shrink more during curing. This creates tension at the edges. Especially with Shellac: two or three thin layers are better than one thick one.

5. Incorrect or insufficient curing

If the product isn't cured long enough or with an unsuitable lamp, it stays soft underneath and loses its grip. Stick to the manufacturer's curing times and use a lamp that matches your products. According to its description, the BNC UV/LED Lamp 26 Watt cures LED gels, UV gels and UV polishes such as Shellac (365 & 405 nm). For salons, the BNC Curing Lamp 168 Watt with 36 dual LEDs offers plenty of room for the whole hand. Also make sure to place the thumb separately and flat under the light.

6. Primer forgotten or used incorrectly

A bonding agent connects the natural nail and the enhancement. The acid-free BNC Primer Ultra Bond is gentle and, according to its description, also suitable for adhesion problems and problem nails. For stubborn lifting with gel or acrylic, the acid-based BNC B5 Acid Primer can strengthen adhesion further – apply sparingly and only to the natural nail. We explain the difference between the two in B5 Acid Primer vs. Nail Prep.

7. Free edge not capped

If you don't "seal" the tip of the nail with every layer, water gets in from the front in everyday life and the polish chips. Run the brush gently along the free edge once with base, colour and top coat.

8. Nail type and external factors

Very oily, very moist, soft or strongly curved nails are more prone to lifting. Frequent contact with water, cleaning products or solvents, hormonal changes or medication can also affect adhesion. What helps here is particularly thorough preparation, a suitable primer and a base gel such as BNC Masterline UV/LED Base Bonding Gel clear.

Recognising symptoms: what's the cause?

Where the product comes away tells you a lot about the cause. Use this overview as a quick troubleshooting guide:

Step by step: how to prepare the nail properly

1. Clean and disinfect hands: wash hands, dry them well and wait a few minutes so the nail isn't saturated with moisture.
2. Push back the cuticle: gently push back the cuticle and completely remove the invisible cuticle from the nail plate.
3. File the shape: file the desired shape, always in one direction so the edge doesn't split.
4. Remove the shine: buff the nail surface evenly with a fine buffer – without pressure, the natural nail shouldn't be filed thin.
5. Remove dust and degrease: brush off the filing dust and wipe the nail with BNC Cleaner Clear, which degreases and disinfects natural nails. Don't touch it afterwards.
6. Dehydrate: apply a thin layer of BNC Nail-Prep and let it dry for about 30 seconds.
7. Apply primer: only on the natural nail, not on the skin. Let Primer Ultra Bond air-dry for about 30 seconds.
8. Thin first layer: work a thin layer of base or bonding gel into the nail, leave a gap to the cuticle, cap the free edge and cure fully.
9. Remove the sticky layer: after the final cure, wipe off the sticky layer with BNC Cleaner Pink or Cleaner Clear – if your top coat has one.

Shellac not lasting? What you can do specifically

With UV polish the layers are especially thin, so small mistakes show up faster. These points make the difference:

• Use base coat, colour and top coat from one system and cure every layer fully.
• Apply colour in two thin layers rather than one thick one – otherwise the polish wrinkles or stays soft underneath.
• Cap the free edge with every layer.
• Avoid long exposure to hot water (bathing, washing up) in the first few hours after application.
• Don't pick the polish off to remove it – soak it instead, for example with BNC Soak Off Remover with Lanolin, which gently removes hybrid and Shellac polishes.

FAQ: gel nails and Shellac lifting

Why do my gel nails always lift at the cuticle?

Usually the invisible cuticle wasn't removed completely or the gel touched the skin. Leave a fine gap when applying and work the cuticle carefully beforehand.

How long should Shellac last?

With clean preparation and application, UV polish usually lasts two to three weeks. If it chips after just a few days, take a closer look at degreasing, layer thickness and curing.

Do I need a primer for Shellac?

On normal nails, good preparation with a dehydrator and base coat is often enough. On oily nails or if chipping keeps happening, an acid-free primer can improve adhesion.

Can the lamp be to blame when gel nails lift?

Yes. If the power is too low, the curing time too short or the wavelength doesn't match the product, the gel won't cure fully. Check the manufacturer's instructions and make sure all fingers sit evenly in the light.

Can I simply peel off lifted gel nails?

Please don't. Pulling them off takes top layers of the natural nail with it, leaving the nail thin and sensitive. Remove the product by filing or soaking instead, or have it removed at a salon.

What helps with very oily nails?

Degrease thoroughly, dehydrate right before application and use a suitable primer. Don't touch the nail with your fingers once it's prepped.
