Use a spatula.

A prop I love using these days for base makeup!

This is a Picasso spatula.

I saw on a makeup YouTube channel before that a lot of people use this.

I bought it on Coupang and tried it out.

I liked that it spread out thinly.

It hardly counts as makeup; just apply sunscreen, spread BB cream thinly with this, and gently pat with a puff for a close-fitting finish.
