Excellent product, moisturizes my poor wrecked cuticles!
I bought this when it first launched because all the other cuticle treatments were disappointing, still leaving my cuticles jagged and rough., despite me using multiple times a day. Wow was I impressed. My cuticles (and nails) now look so hydrated and healthy. I’ve since purchased 3 more times and will continue to do so. I have one in the car, one on the coffee table where I do my nightly treatments, and one by my toothbrush. I do the illuminating nail concealer and now my nails look like I had a salon manicure. If they sold this by the quart I would buy it!
Love this ! If cuticles are really dry or rough really helps to get them in better condition!🥰👍
Great product
EASY TO USE WITH GREAT RESULTS!
