Perfume houses are companies that specialize in creating and producing fragrances. They develop unique scents by blending various essential oils, aroma compounds, and other ingredients. These houses often have a team of skilled perfumers, known as noses, who craft the fragrances based on specific themes or concepts. Many perfume houses also focus on branding and marketing their products to appeal to different consumer preferences. They may offer a range of perfumes, from luxury to more affordable options, and often collaborate with fashion designers or celebrities to create signature scents that enhance their brand identity.
