I use one that adheres well to the skin.

I apply the COSRX Skin Booster Serum to prepare the base of my skin first.

After applying it, it feels like it absorbs deep into the skin and makes it firm and supple.

After that, I do a simple moisturizer and sun care.

I considered it a basic step, so I spread the sun serum evenly. It feels smooth and radiant.
