No complex setup is required for these products; they are ready to use directly from the packaging. To preserve the integrity and longevity of the fragrance, store both the Eau De Toilette and shower gels in a cool, dry place, away from direct sunlight and extreme temperatures. These products are formulated for adult male skin. While generally compatible with most skin types, if you have sensitive skin, it is always recommended to perform a patch test on a small, inconspicuous area before full application of either the Eau De Toilette or the shower gel. Avoid direct contact with eyes. For a consistent scent, using the matching shower gels is recommended over other scented products.
