Fragrance is intensified by the warmth of your own body. Apply the YSL Y cologne in the creases of your knees and elbows for a longerlasting, stronger scent. After applying, avoid rubbing or dabbing skin. This breaks down the fragrance, causing it to wear off more quickly. If you prefer placing fragrance on your wrists, be sure to reapply after frequent handwashing, as this tends to rinse off the scent.
