butter LONDON Nail Strengthener for Damaged Nails, Mellow the Yellow – Nail Hardener & Strengthener Polish Exfoliates, Brightens & Rejuvenates Yellow & Dry Nail Beds & Roots – Nail Care Products

Subtle shine
The big Butter London square cap pops off, and there is a standard sized cap underneath, with no-slip grooves in it. I did need some pliers to loosen the cap the first use, and it’s been an easy hand-open every time after that.I don’t have yellowing nails, so I can’t address that – I bought this because I saw a picture and liked the color.The color and shine are gorgeous. I have light skin with a lot of pink in it. This polish is glossy with a *hint* of muted pink to it, which makes my nails look uniform and pretty, but not unnatural. If I put on my peeper glasses I can see there is a very fine purple glitter to it, but nothing like a glittery nail polish. I usually go with one or two coats, and it’s plenty shiny, but doesn’t have that heavy, glassy, sticky lipgloss looking shine that my clear coats have.The coverage is smooth and forgiving of my less-than-perfect application.It seems very durable. I have six children and no dishwasher, and as the polish inevitably wears down or chips, the color and sheen are so subtle, the wear isn’t immediately noticeable. I only apply polish once a week – it definably needs redoing by day 7, but nothing like my color polishes – those look downright tatty by day seven. (My color polishes are also brands like Butter London, OPI, and Essie. It probably doesn’t stick better, just looks less drastic as it wears.)

Good for yellow
It’s great for yellow, but not good for the white spots that you get in your nails

Natural, fresh nails
I love this product and keep giving it to friends as a gift. My nails get yellow easily – I think it’s age? – and I searched for nail color that would give me a natural look. For me, this is better than a colored polish. It just makes my hands look clean and fresh. Dries quickly, lasts nicely. I am hooked!

Pricey polish
My nails are quite stained and using this product made them look normal. In bright light you can see the blue iridescence but not overwhelming. I tried it on the 7th and removing on the 18. It started chipping. Pricey! I’m going to try the base coat next, hopefully it works well so I’m not staining my nails even more. Update: I reapplied this polish and applied a nail polish over it. Wow! 8 days and still going strong. But I need a top coat because the nail polish lost it shine. This is worth it. No improvement in growth but very strong. Buy it!!!

This product is on the pricey side, but it does work. Have been super frustrated with my nail yellowing from constantly painting my nails, but this product is a life saver, especially when you want to get a break from color without but are embarrassed by your stained nails.
