A special code saves 20% off the new and improved formula, which is said to be ‘elegant and classy all while strengthening the nails’
Brittle nails can be caused by a range of factors, from ageing and medical conditions, to frequent exposure to harsh chemicals and moisture loss. For those whose nails are constantly splitting, peeling or snapping it can be a real frustration, but according to shoppers, a £16 treatment could be the shortcut to stronger, healthier-looking nails in as little as seven days.
Beauty fans dealing with everything from post-gel damage to medical-related brittleness are turning to OPI’s cult-favourite Nail Envy Nail Strengthener. A firm favourite for years, the formula has recently had a major upgrade – and the results have been seriously impressing users, and now using code treat20 saves 20% off the price tag until May 31, 11.59pm.
Previously dubbed the “original nail strengthener”, the revamped Nail Envy formula is now being hailed as the “new OG” thanks to its updated vegan formula and added tech. The new and improved Nail Envy is said to provide advanced strengthening for 95% stronger nails in a week.

The formula features Tri-Flex Technology, designed to create a liquid shield over the nail. This helps reinforce the surface while building strength layer by layer – ideal if your nails are prone to chipping, peeling or splitting. It also includes biotin, vitamins A, C, E, and calcium to nourish nails.
For those dealing with more severe damage, Nail Envy is designed to be paired with OPI Repair Mode – a bond-building nail serum that works beneath the surface. Using Ulti-Plex Technology, Repair Mode penetrates the nail to rebuild keratin structure from within, with claims of up to 99% keratin repair after consistent use.
“OPI Classic” Nail Envy Nail Strengthener (Sheer Colour)

This iconic, sheer coloured nail strengthener now features Tri-Flex Technology to strengthen and protect nails against chipping, peeling, and splitting.
Applied twice daily for six days, it targets deeper damage before you layer Nail Envy on top to maintain strength and protection. Nail Envy should be applied once per day for six days, with two coats on nails for the first application and one coat on nails for the following five days.
While the OPI Classic Nail Envy Nail Strengthener Sheer Colour offers a natural look, manicure fans needn’t ditch their favourite shades. The formula has been released in six new colours, from sheer pinks to deeper tones like red and navy, all without sacrificing nail health. Usually £23, they’re currently reduced to £16.10 for a limited time.
Elsewhere, at LookFantastic , there’s the Manucurist Active Smooth 00 15ml for £16. The perfecting nail polish and treatment is enriched with castor fibres, hexanal, AHAs and vitamin E to provide a natural-looking wash of colour.
For those with designer taste, though, Dior has a Dior Base Vernis for £30. Designed to strengthen and harden nails, the base provides the ideal smoothness to ensure a flawless finish and optimal manicure wear.
But at OPI, their Nail Envy is backed by a 4.3 star rating based on more than 900 reviews. One said: “I have weak, brittle nails which tend to peel at times. This product made my nails look and feel stronger. I hate the appearance of my nails and usually cover them with coloured nail polish. This polish gives a slight pink tint to the nail so I felt comfortable with my ‘bare’ nails.”
Another added: “I absolutely love this product. I’ve always struggled to grow my nails without breakages and this product is just perfect to strengthen your natural nails. It enhances growth and creates such beautiful and salon-perfect nails.”
Even those with medical reasons for brittle nails have been impressed. One said: “My chemotherapy treatment has left me with brittle nails that split easily. OPI Nail Envy seems to be helping.”
“My nails were badly damaged after gel nails (I’m on blood thinners), and the nail bed was bruised, and the nails broke at the slightest touch,” said another. “Nail Envy strengthened them within a week.”
Not everyone has been sold, though, as some have found the application difficult. A three-star review read: “Very thick and doesn’t go on your nail smoothly and shows brush marks.”
Though another commented: “OPI just doesn’t disappoint! This nail strengthener glided on seamlessly and stayed on for ages. The pink sheen made the tips look elegant and classy all while strengthening the nails.”
For those whose nails are in a constant cycle of breakage, this affordable treatment could be worth a try – especially for those looking for a low-effort alternative to gels or acrylics. Code treat20 saves 20% off the price tag until May 31, 11.59pm.
