Apply serum to strong nails in advance

I apply Innisfree Nail Serum 2 to 3 times a month as a nail health checkup.

It doesn't have any color, and you don't see immediate results just by applying it.

I feel like my nail health is being maintained.

For a long time, my nails broke too frequently, and I wasn't applying the nail serum above when they broke.

Since I discovered nail serum, I find myself constantly forgetting about my nails breaking while I use it.

I brought this home after seeing my friend use it, so once I finish this one, I think I'll buy two and give one to my friend.
