In recent years, the Inside-Out Beauty trend, which combines health and beauty, has gained significant traction in the UK. This approach emphasizes managing external beauty through internal health, closely resembling Korea’s Inner Beauty concept. Driven by growing consumer interest in healthy lifestyles, this trend is expected to maintain steady growth, with an annual growth rate of 2% projected through 2027. Notably, inner beauty products have garnered attention across various categories, including skin, hair, and gut health.
Popular Skin Health Supplements: Collagen and Biotin
In the UK, health supplements such as collagen and biotin are particularly popular. Collagen, known for its benefits in improving skin elasticity and combating aging, is available in diverse forms, including powders, capsules, and jellies. Collagen drinks, which gained viral popularity on social media, have seen a sharp increase in sales among younger consumers. Biotin, recognized for promoting hair and nail health, has experienced rising demand, particularly among individuals concerned about hair loss. Other products, such as probiotics for gut health and skin benefits and apple cider vinegar for blood sugar regulation, are also steadily gaining attention.
2024 Multi-functional and Probiotics Products
In 2024, the concept of inside-out beauty has further shaped trends in health supplements for skin health, with multifunctional products and those based on natural ingredients taking center stage. Approximately 70% of the immune cells in our body are located in the gut, and the balance between beneficial and harmful bacteria in the gut plays a significant role in skin health. When this balance is disrupted, it can heighten inflammatory responses, leading to various skin issues such as acne, atopic dermatitis and psoriasis. So, this growing awareness among consumers has led to the rising popularity of formulations that combine collagen, vitamins, and minerals as well as products enriched with probiotics. As scientific evidence and transparency become increasingly critical, collaborating with specialized private label supplements manufacturers like Kolmar BNH is essential for developing products that go beyond beauty to promote overall health.
2025 Projections: AI and Preventive Skincare Solutions

Looking ahead to 2025, advancements in AI-powered skin analysis and personalized product recommendations are expected to drive the development of AI-based tailored solutions. Technologies such as exosomes, known for their potential in cell regeneration and anti-aging, are also anticipated to gain prominence. Preventive care products that focus on strengthening the skin barrier and minimizing moisture loss, particularly those containing ectoine, are likely to attract more attention. These shifts will be driven by heightened consumer awareness of health, technological advancements, and a growing emphasis on sustainability. The integration of cutting-edge technologies like AI and the development of evidence-based products will be more important than ever.
Beside AI, thanks to active promotion by social media influencers, consumer interest in collagen has surged with growing attention to the concept of collagen banking which stimulates and stores collagen for future use. According to Mintel, 34% of beauty supplement users seek collagen, making it one of the most popular ingredients while 22% of adults consuming beauty and grooming products view it as offering lasting effects. Many collagen buyers for beauty purposes are under 25 reflecting a rising trend among younger consumers who prioritize preventive measures over waiting for visible signs of aging. This demographic is drawn to convenient, tasty, and innovative formats like jelly-based supplements, moving away from traditional pills, powders and pouches. Sustainability and clean labels are also key factors influencing their purchasing decisions.
Global Trends in Skin Health Supplements

The global health supplement market continues to evolve, reflecting regional preferences. In Asia, traditional herbs and the Beauty-from-Within trend dominate, while North America sees rising demand for multifunctional products such as vitamin C and collagen, backed by scientific evidence. In the UK and Europe, there is a strong focus on eco-friendly and sustainable products, with high demand for solutions catering to sensitive and dry skin, as well as lightweight textures. Meanwhile, in the Middle East, the younger demographic is driving increased demand for beauty supplements. These trends are expected to persist, making it essential for companies to leverage private label supplements to develop personalized products and strengthen marketing strategies.
In conclusion, the inside-out beauty trend, which bridges health and beauty, is poised for continued growth in the UK and global markets. Within this dynamic landscape, specialized private label supplements manufacturers like Kolmar BNH are key partners in developing customized products and adapting to rapid market changes. Companies must collaborate to deliver innovative solutions and personalized offerings, thereby enhancing their competitive edge in this evolving industry.
