The founder and artistic director of the French cosmetics label Make Up For Ever started her venture in 1984, as there were few products made for professional make-up artists then.
Ms Sanz started out doing make-up backstage for theatre, television and film, so she has a good grasp of what her colleagues want from their products.
The brand was acquired by French luxury conglomerate Moet Hennessy Louis Vuitton in 1999.
Today, the brand is known for its bold colours, waterproof formulas and high-definition range (which was made to help mask the imperfections of actors and TV anchors who have to face super-clear high-definition cameras).
What is the one product that you would not step out of the house without?
I always carry a pressed powder with me, because it is the one item that you can use to touch up your make-up no matter where you are.
The Make Up For Ever High Definition Pressed Powder sets make-up, mattifies and adds a glow to the face.
What is your favourite perfume?
It is a scent by Montana.
Unfortunately, they do not carry it anymore in the stores. When I found out that it was going to be discontinued, I purchased enough of it to last me for a long time.
I have been wearing this perfume for 20 years and I simply cannot imagine wearing any other one.
What is the best beauty invention?
It is definitely the cream blush, an item that every woman should own. Cream blush does not dry the skin and can add youthfulness to the skin with a natural flush.
What is the most ridiculous thing you have done in the name of beauty?
I cannot say that I have done any ridiculous thing in the name of beauty.
But one of the most amazing things I have had a chance to do is to teach blind women how to wear make-up.
They, like any other woman, are concerned about their appearance.
My goal is to help them restore their confidence. It makes me happy when I see how they completely trust me during their make-up lessons.
