My nails get pretty brittle from working in gloves and sticking my hands in soapy water. So after work, I use this on its own or with the Innisfree Nail Strengthener and my nails are almost brand new the next day. Aids in faster growth and stronger nails. The product does have a serum and oil, so you have to shake it before use. There is a slight floral smell if you get close enough, but its very pleasant and light. Will definitely purchase again and again.
