I really, really, really wanted to love this. But sadly, it was not love at first sight (or even love after a month of religious trial). First off, nowhere could I find what oils are in the bottle. This was a concern, as the Revitanail Strengthener contains formaldehyde. But, let's pretend it's all kosher.
Sadly, the oils are watery. If that's even a thing. It wasn't nice and thick, nor did it smell overly pleasant. The brush is quite stiff and wiry, I would have liked a dropper better. It did rub in ok, but it felt a little too greasy.
I really didn't notice any improvement in the condition of my cuticles (and trust me, they were not in tip top condition to start with). An underwhelming, unknown quantity. I'll stick to my Skinfood Coco+Nut oil, or just good old Rosehip thanks.
I like a several of the Revitanail products, but this one let me down a little. The main issue I have is the brush - it's quite coarse, and feels weird when applying the oil. The oil itself is fine, rubs into the cuticles fine, no offensive smell. If only the brush was not coarse plastic - a dropper would have been better. Good sized bottle.
