What It Is: A silky hydrating serum infused with apricot kernel oil that strengthens the nails, softens the cuticles and protects them from drying out. What It Does: A key step in the Dior manicure, applying Huile Abricot nail serum to the nails and cuticles helps hydrate them. Infused with apricot kernel oil, the silky-smooth, non-greasy formula also softens the cuticles and reduces the risk of nails splitting or breaking. How to Use: Apply a drop of Huile Abricot cuticle serum and massage over the entire nail surface to help it absorb. Use daily, morning or night. If you are applying nail polish right after this step, be sure to wash and dry your nails first. 0.25-oz.
