Will nail cuticle nail oil be effective?

The first photo shows the hand before receiving care.

The second photo is from when I received basic nail care today.

After receiving nail care

Applying nail supplements and oil to the skin around the nails makes them shine brightly.

Since there was another customer's reservation and it was my first time visiting this place today,

I couldn't hear the detailed explanation.

I think applying nail oil before going to sleep can help keep my nails a bit more moisturized.

Has anyone used a product called nail oil?

I'm curious if it is effective.

I want to buy and try applying nail oil if it only has effects.

Seeing my hands become smooth and free of cuticles made me realize I need to take care of them.

If you have any products that you have seen effective from using nail supplements and nail oil, please recommend them.
