You believe true beauty is in the details, and your nails are a non-negotiable part of your overall presentation. You want a product that provides both nourishing care and a smooth, perfected, 'my nails but better' finish.

Nourishes Without the Greasy Feel

Users say it 'sinks right in' and doesn't leave a sticky residue, so you can use it and go about your day immediately.

Tackles Dry, Ragged Cuticles

Helps soften and smooth the skin around your nails. Reviewers note cuticles are 'less likely to peel' and look 'neater' with regular use.

Fortifies Nails Against Daily Stress

Modern life with constant hand washing and typing can weaken nails. This serum helps reinforce them from the base up for better resilience.

Promotes a Naturally Healthier Shine

Works to improve the nail plate's condition for a clean, natural gloss, not a synthetic topcoat shine.

Reduces Peeling and Splitting

By delivering key nutrients to the nail matrix, it helps support stronger nail growth that's less prone to layers separating.

Gentle Enough for Sensitive Users

The fragrance-free, carefully screened formula is a go-to for those who say other treatments 'cause irritation'.

Simplifies Your Nail Care Routine

One simple step replaces multiple products. It's the 'easy' part of a routine that people actually stick with.

Supports Nail Growth from the Source

Focuses on nourishing the area where nails are made, helping to set the stage for healthier growth over time.

Kose, a trusted name in Japanese beauty since 1946, saw a gap in nail care. Most treatments were harsh or temporary. Their labs in Tokyo developed this serum foundation to nourish nails from within, the way Japanese skincare treats skin. The formula centers on 7 key ingredients, including patented ceramide complexes and botanical oils, selected for their proven ability to support the nail matrix. Every batch is produced in a Japanese GMP-certified facility, ensuring pharmaceutical-grade purity and consistency. It's not just lab-tested; it's loved, consistently ranking as a top-selling nail treatment in its category for its gentle, effective approach to stronger, healthier-looking nails.

Kose Nail Holic 24/7 Serum Foundation - Nourishing Nail Treatment is formulated with a blend of key ingredients designed to strengthen, nourish, and protect nails. The product contains hydrolyzed keratin, which is included to reinforce the nail structure by penetrating the nail plate and improving its resilience against breakage and splitting. It also features panthenol (provitamin B5), which acts as a humectant to retain moisture, preventing dryness and brittleness while promoting flexibility. Additionally, the formula includes jojoba oil, rich in fatty acids and vitamins, to condition the nail bed and cuticles, enhancing overall nail health and appearance. The presence of silica helps to smooth the nail surface, reducing ridges and creating a polished finish. These ingredients work synergistically to provide long-lasting hydration, improve nail strength, and support healthy growth, making it an effective treatment for maintaining strong, well-nourished nails.
