Yves Saint Laurent Opium Homme eau de toilette is very suitable for daily use. An eau de toilette has 6% to 12% perfume oil, which makes it a lot more subtle than an eau de parfum. Yves Saint Laurent Opium Homme eau de toilette is therefore perfect to wear to the office, for instance. If you want to enhance the scent a little more, you can combine the fragrance with Yves Saint Laurent Opium Homme skincare products, or you can fill a small atomizer with the eau de toilette for quick touch ups.
