Key Industry Insights on Skin Nutrition

The concept that beautiful skin begins with diet is rapidly gaining recognition across the health and beauty sectors. As C. Faria‑Silva (2020) notes, the link between what we eat and skin health is no longer a fringe idea but a growing phenomenon in both research and consumer behaviour. Nutrition is now recognised as a critical factor in all biological processes affecting the skin, including ageing, disease prevention and recovery from inflammatory conditions (News‑Medical, 2025).

Market Growth Reflects Consumer Awareness

The global skin health supplements and treatment market was valued at USD 6.1 billion in 2023 and is expected to grow at a CAGR of over 8.1% from 2024 to 2032, driven by rising wellness consciousness and increased concern for skin health (Global Market Insights Inc.). Similarly, the professional skincare market is projected to expand from US$ 43.14 billion in 2024 to US$ 45.57 billion in 2025, powered by technological advancements, consumer education and a flourishing beauty industry (The Business Research Company). The global skin-health foods market is also experiencing remarkable growth, forecasted to rise from US$ 2.1 billion in 2022 to US$ 3.5 billion by 2030 (Research and Markets).

Nutrition and Dermatology: An Interconnected Discipline

Recent literature underscores the intrinsic link between nutrition and dermatology. S. Assaf & O. Kelly (2024) and the Nutrients Special Issue on “Nutrition and Dermatology” highlight how nutritional dermatology is an emerging field of interest, although further research is needed to fully understand the complex interplay between diet and skin outcomes. Epidemiological studies indicate that abundant intake of plant-based foods plays a crucial role in maintaining skin barrier function and overall health (Fam et al., 2022).

From Research to Clinical Practice

Medical nutrition therapy has gained attention for its potential to influence dermatological outcomes. L. Barrea et al. (2025) emphasise the link between nutrition, inflammation and oxidative stress, showing that antioxidant-rich diets can slow skin ageing, while diets high in refined sugars and trans fats accelerate it (News‑Medical, 2025). The advancement of nutritional science now considers dietary patterns rather than single nutrients, strengthening the connection between diet and the incidence or severity of dermatological conditions (Cartwright, 2025).

Professional Opportunities and Education

The industry is responding to these insights with specialised training for dietitians and nutrition professionals. Certified programmes equip practitioners to support clients with chronic or inflammatory skin conditions, premature ageing and general skin wellness (SkinWellnessPro.com, 2025). Clients increasingly seek guidance on managing acne, eczema, dullness and other skin concerns through diet, highlighting the demand for professional expertise in nutritional dermatology.

Plant-Focused Nutrition for Skin Health

Across the literature, a consistent theme is the emphasis on fresh, seasonal, minimally processed, plant-focused foods to promote skin health (Gürtler et al., 2022). Such dietary approaches address oxidative stress, inflammation and skin barrier integrity, offering tangible benefits for both preventive and therapeutic dermatology.

Conclusion

In summary, skin nutrition is now recognised as both a consumer priority and a professional opportunity. With global markets expanding and research continually linking diet to dermatological outcomes, skincare professionals and nutritionists are uniquely positioned to leverage these insights to deliver evidence-based guidance, improving client outcomes while supporting the growth of the industry.
