Key Ingredients

Benzophenone-1

A UV absorber that helps to protect nails from harmful UV radiation, which can cause damage, discolouration, and fading of nail polish. Its antimicrobial properties help to prevent the growth of harmful bacteria and fungi.

Hexanal

A natural, plant-derived ingredient which works by strengthening the keratin cells, reducing the risk of breakage and splitting. It can help to smooth and hydrate nails, improve strength and flexibility, and promote healthy nail growth.

Silica

A mineral used to strengthen and harden nails by forming a protective barrier which can help to prevent brittleness and breakages. Silica also has moisturising and nourishing properties, which can help to improve the overall health and appearance of nails.

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.

Glycerin

A popular ingredient in nail care products due to its moisturising properties which helps to hydrate and nourish the nails preventing dryness and cracking, as well as promoting healthy growth.

Tocopherol and Tocopheryl Acetate

A powerful antioxidant that can help protect nails from free radicals and environmental damage. It also helps to moisturise and strengthen the nails, promoting healthy growth. Vitamin E can also aid in preventing nail splitting and peeling, promoting a smooth and even nail surface.

Panax Ginseng Root Extract

Ginseng root has been used in traditional medicine for centuries. It contains several important compounds that can help to strengthen and protect nails as well as stimulate blood flow to the nail bed, helping to promote nail growth. Anti-inflammatory and antimicrobial properties help to prevent infections and soothe irritation, promoting overall nail health.

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.

Prunus Cerasus Flower Extract

Rich in antioxidants and flavonoids, its nourishing and moisturising properties can help protect and condition the nails reducing the risk of brittleness. Its antimicrobial and anti-fungal properties help to prevent infections and promote healthy nail growth.

Aloe Barbadensis (Aloe Vera) Leaf Extract

A natural ingredient rich in vitamins, minerals, and antioxidants. Its moisturising properties help to nourish and hydrate the nails, reducing dryness and brittleness. It also has anti-inflammatory and antimicrobial properties which help to prevent infections and soothe irritation, promoting overall nail health.

Helianthus Annuus Seed Oil

Rich in essential fatty acids including Linoleic Acid and Vitamin E, which in addition to moisturising properties can provide antioxidant benefits. These have the double benefit of protecting the nails from damage caused by environmental stressors, while nourishing to promote healthy nail growth and resistance to further damage.

Glycine Soja Oil

High in vitamin E and other fatty acids which can help to moisturise and nourish the nails, improving strength while maintaining flexibility. This is critical for preventing breaking or splitting. It is also a source of Biotin, an essential B vitamin which helps strengthen the nails and promote healthy nail growth.

Punica Granatum Seed Oil

A rich source of antioxidants and antimicrobial compounds, which can prevent redness, swelling or irritation, while also protecting from the growth of harmful bacteria and fungi that cause infections. It is also a rich source of fatty acids such as Punicic Acid, which help strengthen the nails and promote healthy nail growth.

Vitis Vinifera Fruit Extract

Rich in polyphenols and other antioxidants, which can help to protect nails from damage caused by free radicals. Free radicals can cause oxidative stress, which can lead to weakened nails, discolouration, and other signs of ageing. As well as having moisturising emollients, Grape Extract contains vitamins and minerals like vitamin E, vitamin C, and calcium that are important for healthy nail growth.

FAQs

People with healthy nails seeking to strengthen them.

  1. People with damaged, brittle, or splitting nails. We recommend using the Ultimate Nail Rescue Set first. Once your nails are back in a healthy state, then you can transition to Miracle Base Coat.
  2. People experiencing fungal or bacterial nail infections.
  3. Children. Solvent based products (such as nail polish and nail polish remover) should not be used on children.

Always read ingredients, perform patch tests and discontinue use if any adverse reactions occur. Consult a dermatologist or healthcare provider with concerns.

No. For flaking nails, consider alternatives such as our Ultimate Nail Rescue Set specifically formulated to address this issue.

It’s pretty unlikely. If your nails are damaged, it's advisable to exercise caution when considering the use of a nail hardener or any other solvent based products such as nail polish and nail polish remover. Using a nail hardener on damaged nails could potentially worsen the condition.

It's essential to address the underlying issues causing the damage and consult a healthcare professional for appropriate treatment before considering the use of a nail hardener.

Dry, peeling or splitting nails can result from various factors, including exposure to water, harsh chemicals and solvents. Minimising exposure to such substances and using moisturising products like our Rest & Repair Mask can help maintain nail health.

If you are experiencing dry, peeling or splitting nails, we recommend you immediately stop using products that could be dehydrating your nails (i.e. nail polish, nail polish remover, hand sanitiser and anything else solvent or alcohol based) and minimise exposure to water and chemicals by wearing gloves for chores.

Wish I had purchase sooner

I was a bit skeptical based on the instagram targeting but the results have far exceeded my expectations. I hard previously been using a Sally Hansen hardener and/or a Mavala hardener but didn’t see any changes. I’ve been using KB Miracle Base coat for 4 weeks now, after a summer of back to back gel nails, and my nails are the longest and strongest they’ve been in years. This is also the longest I’ve gone without breaking a nail. Highly recommend! - oh and it looks pretty too
