I'd like a recommendation for a nail strengthener that's like nail polish.

I bought this Wake Make Pink Nourishing Serum with my own money, and it's affordable and easy to apply. I usually avoid nail polish because it feels heavy and suffocating, but this doesn't give me that feeling at all. It's pink, but not too intense; it gives a natural flush of color. I use it as a substitute for nail polish, applying it about three times. I recommend this to those who find nail polish a bit too much, and to anyone who wants both nourishment and color. Go check it out at Olive Young!!
