YSL Beauty is the beauty arm of the French Yves Saint Laurent and was introduced in 1978. YSL stepped into the world of beauty with perfume and soon after expanded into cosmetics which they describe as high end and luxe but edgy and youthful. I have to admit that I am drawn to the fancy gold packaging of this product line but they do have some quality products that I keep on hand.
