Whether you are in a rush, or you're missing the appropriate tools- brushes are not always necessary for makeup application. Galit Strugano, Creative Director at Girlactik Beauty, suggests using your fingers instead of synthetic or natural brushes. By using your fingers, you can benefit from the natural heat and oils in your skin and melt the product for a smoother application. She also explains that each finger applies a different pressure, meaning one is better for patting on concealer and another for spreading eye shadow, etc. I'm actually a fan of using my fingers for makeup application. See below for some tips & tricks:

Ring Finger for Concealer

Using your fourth finger allows for a softer touch when applying concealer, so you make sure you’re not pulling the skin in such a sensitive area. 

Index Finger for Shadow

This finger possesses a little more pressure but still has a gentle touch so that your shadow spreads evenly.

Middle Finger for Eye Crease

The middle finger is the strongest, so it’s ideal for framing your eye, creating definition as you move it back and forth.

Pinky for Inner Eye

Your smallest finger is perfect for applying makeup to those hard-to-reach places. It has the least strength of all.
