butter LONDON Illuminating Nail Concealer sheer brightening treatment — 10‑Free base/top coat with vitamin E & lemon extract

This lightweight, opalescent formula blends vitamin E with natural exfoliants like lemon fruit extract to soften the appearance of discoloration and add shine. Formulated without common toxins (10-free), it’s created to be a feel-good addition to your nail routine that supports stronger-looking, more luminous nails over time when used regularly.

How does this product brighten yellowing or discolored nails?

The concealer uses a soft pearlescent pigment to immediately neutralize yellow tones while gentle exfoliants work to smooth and restore nail surface brightness. Visible improvement in overall nail tone can appear with repeated use as the formula helps reduce surface dullness.

• Opalescent pigments hide yellowing on contact
• Lemon fruit extract helps gently exfoliate dry, uneven nail surfaces
• Vitamin E conditions and supports nail appearance
• Use alone or layered for increased opacity

Can I use it as a base coat, top coat, and everyday polish?

Yes — the design is intentionally multifunctional so you can streamline your manicure steps. Apply a single coat to bare nails for a quick brightening treatment, two to three thin coats for more coverage, or use it under and over color as a smoothing base or finishing top coat.

• One coat: brightening treatment and subtle sheen
• Two to three coats: more opaque, polished finish
• Works under colored polish as a base and over polish as a glossy seal
• Reapply during the week as a touch-up for ongoing brightness

Is the formula safe and what does "10-free" mean?

butter LONDON’s 10-free claim means this nail treatment avoids ten commonly used harmful ingredients and uses cruelty-free, skin-conscious components. The formula focuses on safer, cleaner alternatives while delivering salon-style performance without compromising on shine or wear.

• Free of formaldehyde, DBP, toluene, camphor and other common toxins
• Cruelty-free and made with good-for-you ingredient choices
• Gentle enough for frequent use as part of a maintenance routine

How do I use it to see the best results?

Start with clean, dry nails and apply one thin coat. For more coverage, layer additional thin coats allowing brief drying time between each. Reapply as needed during the week and expect improved surface brightness with consistent use.

• Apply to clean, dry, bare nails
• Layer 2–3 thin coats for a more opaque effect
• Use as base coat, top coat, or standalone treatment
• Touch up throughout the week to maintain brightness

Who is this for: butter LONDON Illuminating Nail Concealer is ideal for anyone wanting an easy, non-invasive way to improve nail appearance — especially people with dull or slightly yellowed nails who prefer clean, multi-use beauty products. It suits those who want salon-finish shine without harsh additives and those who favor simple, effective nail care that works as both treatment and polish.
