Fragrance layering, also referred to as perfume layering, involves blending multiple perfumes or scented products to craft a distinctive and personalized olfactory experience. Rather than relying on a single fragrance, this technique entails applying the rollerball oil scent first and then the spray to create different scents thoughtfully and strategically to achieve a richer and more individualized aroma. Here at Oud & Oudh London we speacially crafted these Oud layering sets so that no matter where you are you are always smelling your best.
