Market segmentation is the process of dividing a large, homogeneous market into clearly identifiable segments with similar needs, wants, or demand characteristics. It enhances a company's focus, boosts competitiveness, helps with market expansion, and provides guidelines for resource allocation. Nivea Sun segmented the UK sun care market based on consumer attitudes toward sun care into five segments: concerned consumers, sun avoiders, conscientious sun lovers, careless tanners, and naive beauty conscious. This helped Nivea Sun understand consumers better and launch innovative products tailored to each segment, such as easy-to-apply sprays, immediate protection formulations, and advertising targeted toward female purchasers. Market segmentation was key to Nivea Sun's success
