Review: Gorgeous Shimmer & Instant Strength for Damaged Nails! - I absolutely love butter LONDON Mellow the Yellow Nail Strengthener! The shimmery color is beautiful and gives my nails a healthy, polished look without needing extra layers. The application was incredibly smooth, and I was amazed at how instantly my damaged nails felt stronger. It’s lightweight yet effective, making my nails look brighter and healthier right away. This polish is perfect for anyone dealing with brittle or discolored nails—it exfoliates, strengthens, and enhances their natural beauty all at once. Definitely a must-have for nail care!
Review: 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.)

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