(258)

Nail Care – 3 x 14 ml/0.5 fl.oz.

Clearer-looking nails, instantly and over time. The Yellow Nails Treatment combines Spore No More Base Coat, Supersonic Top Coat, and Self Love Oil for a targeted approach to yellowing and discolouration.

Step 1: Spore No More Base Coat - A clever nail concealer designed to improve the look of yellow or discoloured nails while helping fight the cause. Infused with light-reflecting pearls to disguise stains, lemon extract to brighten over time, and microsilver to support anti-fungal care.

Step 2: Supersonic Top Coat - Seal your treatment with a high-gloss, fast-drying finish. With built-in UV filters, it helps protect against further discolouration while giving nails a polished, salon-quality look.

Step 3: Self Love Oil - The most underrated step in nail care. A nourishing blend of vitamin E, jojoba, and almond oil that strengthens nails, hydrates cuticles, and protects against peeling and cracking. It locks in all the benefits of your treatment while promoting long-term nail health.

Why you'll love this set:

  • Conceals discolouration instantly with light-reflecting pearls
  • Helps brighten and reduce yellowing over time
  • Supports anti-fungal care with microsilver
  • Protects against UV-induced staining and discolouration
  • Strengthens and nourishes nails and cuticles for lasting health

  1. Apply one coat of Spore No More to clean, dry nails.
  2. Follow with Supersonic Top Coat and let dry completely.
  3. Once your manicure is fully set, massage Self Love Oil into nails and cuticles to lock in hydration and protect against peeling and splitting. Use morning and night, and reapply as often as needed.
  4. Remove with a gentle nail polish remover before reapplying Spore No More. Reapply every 5–7 days for best results.

Suitable for fingernails and toenails.

Please note: Spore No More is not a medical treatment — it's a nail polish with anti-fungal ingredients. Apply it once or twice a week as needed. It's best for short-term use, not daily or long-term application. Use it before special occasions to help conceal discolouration and support mild concerns.

Key Ingredients

Argentum

A natural antimicrobial active, silver has been a known antiseptic for centuries. It acts as an antibacterial agent, helping to prevent fungal nail infections, normalise the skin flora and maintain a healthy bacterial balance. It impairs inflammation caused by pathogenic germs and disrupts the multiplication of harmful microorganisms.

Tocopherol

A powerful antioxidant that can help protect nails from free radicals and environmental damage. Vitamin E also moisturises, promoting a smooth and even nail surface while preventing nail splitting and peeling.

Lithothamnion Calcareum Extract

Red algae extract that contains bioactive compounds, including polyphenols and terpenes, with excellent antioxidant properties, protecting skin from free radicals and oxidative stress.

Calcium Pantothenate

Calcium Pantothenate, also known as Vitamin B5, is an essential nutrient that plays a vital role in the growth and maintenance of healthy skin, hair, and nails. Its moisturising properties help to improve the strength and durability of nails, preventing dryness and brittleness and aids in preventing nail infections by strengthening the nails' natural defences against harmful bacteria and fungi.

Citrus Limon Fruit Extract

Rich in vitamins and antioxidants, its astringent and antimicrobial properties can help cleanse and brighten the nails, reducing the risk of yellowing and discolouration. Its moisturising and nourishing properties help to strengthen the nails, promoting overall nail health.

How it works

An anti-fungal nail polish base coat treats and prevents fungal infections while keeping your nails looking their best. It forms a protective barrier, helping to stop fungus in its tracks. Plus, it preps your nails for polish, making it a gentle and effective treatment that fits right into your routine.

FAQs

Our anti-fungal nail polish is here to help you tackle those stubborn fungal infections. It’s a specially crafted formula with anti-fungal agents that work their magic to gently clear up the infection and get your nails back to their fabulous self.

Spore No More Base Coat forms a shield over your nails, packed with anti-fungal goodness, including antiseptic, sanitising and detoxifying ingredients. It seeps into the nail and goes right to work on the fungus, helping to clear things up and bring back that healthy shine over time.

Results can vary, but with a little patience, you'll start seeing improvement in a few weeks to a few months. Nail fungus tends to be a slow mover, so give it time—your healthy, happy nails are on their way!

Spore No More is not a medical treatment — it's a nail polish with anti-fungal ingredients.

Apply it once or twice a week as needed. It's best for short-term use, not daily or long-term application.

Use it before special occasions to help conceal discolouration and support mild concerns.

For ongoing fungal issues, follow a daily treatment plan from your podiatrist.

It's also a helpful preventative if you're prone to nail discolouration or flare-ups.

Absolutely, our anti-fungal nail polish works wonders on both toenails and fingernails. Just a heads-up—while it’s great for all nails, toenail infections can be a bit more stubborn and might take a little extra time to clear up.

If you’re pregnant or breastfeeding, it’s a good idea to chat with your healthcare provider before trying any new treatment, including our anti-fungal nail polish. They’ll help you find the best approach tailored just for you.

To keep those pesky fungal infections at bay, just follow a few simple steps: keep your feet clean and your nails trimmed, avoid going barefoot in public spots, and switch up your socks regularly. And for extra peace of mind, steer clear of sharing nail clippers or shoes with others. Your feet will thank you!

Effective and looks great

I have tried quite a few products with some success but this is by far the best. Your nail immediately looks better and continues to look better daily with the same one application. I actually now have hope my nail will fully recover.
