BY.SU was born from a passion that has always been part of me: real, simple and intentional beauty.

My name is Susana Oliveira. I’ve been a professional makeup artist for many years and throughout my entire journey there’s always been one product that fascinated me more than any other — the lip liner.

Working every day with different faces, styles and needs made me realize something very clear:

A lip liner can change everything.

It defines, corrects, enhances, gives confidence and when it’s truly good, it becomes a part of who you are. But finding the perfect lip liner was never easy. I tested hundreds:

some had the right texture but didn’t last, others lasted but felt dry and some had beautiful color but wouldn’t glide smoothly...

That’s when the idea of creating something of my own was born — something that reflected my vision, my experience and my standards.
