Which Brush Do You Need for Seint Makeup?

This video was so helpful! I’ve had my makeup for a while but really didn’t wear it much because I was working in a medical office where face masks were required and I hated the feel of makeup with masks. Now that I’m retired, I’m ready to dive back in and wear makeup again! Is there a primer that you would recommend?

I am a first time user and i bought a palette and was color matched and I was not told about any brushes so could you guide me to some good brushes. Now I have the palette and no brushes
