I learned about another option for lubricating the needle that is a trick airbrush artists who work in paint mediums use: vegetable glycerin. It's a great lubricant, safe for all metals, and safe for all skin types. So, I tried it and BOOM, works great! It's just another option--we have so many great choices with airbrush makeup. I learn so much watching airbrush MUAs like you. Thank you for posting this!
