I’m truly appreciative of this primer! Working in a skilled nursing facility I am required to wear face masks. I typically wont wear makeup because of the transfer onto my mask and my makeup melting off of my face. However, once I started to wear UR primer there was no more rub off onto my face mask. Even after hours of wear! The only thing left behind on my mama was a spot from my lipgloss rubbing off. This primer definitely does what it says it does.
