Nail biting

Want to stop biting your nails and get healthy, well-groomed hands again, but don't know which treatment to start with? PODERM offers a selection of products specifically designed for bitten nails to help repair damaged nails and promote healthy regrowth. 

Nail biting (onychophagia) weakens keratin, slows nail growth, and increases the risk of infection. Our treatments work on two fronts: they help reduce the urge to bite your nails while repairing the nail matrix so your nails can grow back healthy.

Which treatment should I choose for bitten nails?

Depending on your needs, three complementary approaches:

  • Stop the urge to bite your nails → the Nail Corrector bitter polish. Its bitter taste discourages you from biting your nails and cuticles, without the harsh ingredients found in classic bitter polishes.
  • Repair and regrow → the Bitten Nails serum. It nourishes the nail and surrounding skin, smooths rough cuticles and boosts growth. With no unpleasant taste, it's suitable for the whole family.
  • Speed up regrowth → the Growth Booster with D-Panthenol, to promote the regrowth of bitten nails.

The most effective approach is the combination: the bitter polish for the habit, the serum or booster for repair.

Why choose Poderm treatments to stop biting your nails?
  • Formulated in Switzerland by Maud Falconnet, podiatrist and founder of PODERM
  • The No. 1 brand recommended by podiatrists*
  • Natural active ingredients, free from harsh components
  • Product available in pharmacies

*No. 1 recommended = ISOSKELE - PODERM campaign post-test – study conducted among 303 podiatrists in France – February 2024.

Is bitter nail polish really effective?

It works as a reminder: the bitter taste interrupts the automatic gesture. Combined with a repairing serum, it helps curb nail-biting (onychophagia) and promote nail regrowth.

Serum or bitter polish: which should you choose?

Nail polish curbs nail-biting. The serum, on the other hand, promotes nail regrowth. Both products are complementary.

Are these anti-nail-biting treatments suitable for children?

The serums are suitable for children from age 3, while the polish is suitable for children over 12.

How long before the first results?

The timeframe varies depending on the product used and its formula. Here's what our usage tests showed:

Nail Corrector bitter polish:

  • 100% of testers noticed a reduction in the frequency of nail-biting
  • 100% of testers confirm that the polish creates a protective barrier that promotes healthy regrowth

*Usage test conducted by an independent laboratory on 20 people over 28 days.

Can a color polish be applied on top?

Yes, there's no need to wait for the nail to fully regrow. Once the area is healthy again (nail no longer damaged or irritated from biting), you can apply a color polish without any issue. We recommend our polishes, formulated to respect nail health.

Care for bitten nails is essential to restore the health and appearance of nails after frequent biting habits. Bitten nails are often fragile, deformed, and can be prone to infections. It's crucial to adopt a routine for bitten nails to address these issues.

Start by using treatments for bitten nails that contain silicon, a mineral that strengthens the nail structure and promotes regeneration. Silicon helps improve nail resilience, reducing the risk of breakage and peeling while supporting natural growth.

If infections or irritations are present, choose treatments for bitten nails enriched with Tea Tree oil. This ingredient has antifungal and antibacterial properties, helping to treat and prevent infections while soothing irritations.

In addition to these treatments for bitten nails, ensure you maintain a balanced diet rich in nutrients that support nail growth and health. By incorporating these bitten nail care products into your daily routine, you will promote rapid healing and a lasting improvement in the appearance and strength of your nails.
