These quick-dry drops are supposed to accelerate nail polish drying time. I bought it a while back and stopped using it because it seemed like it actually caused my polish to dry more slowly.
I decided to retest it and make sure my initial impressions were correct. Indeed they were. I put it on a nearly dry manicure and it made my nails wet and tacky. It added HOURS to my dry down time on almost-dry nails. WTF
I should add that with this last test, I used all Orly products - base coat, paint, and top coat. So it's not like it just doesn't work with other brands - it doesn't even work with its own.
