Bought with my own money - Dashing Diva Rich Serum!

Biotin is good for strengthening nails, but...

Personally, I chose this product because I get acne when I take biotin.

Since it is summer, your nails tend to thin and get damaged if you care for them frequently, so it is perfect to apply at that time.

It has a slightly sticky texture, but if I apply it to my nails before bed, my cuticles feel neat the next day.

The brush is slightly curved, making it easy to use even on the curved parts of fingernails and toenails.
