From nature to your skin: Understanding skin nutrients

Skin is not an isolated system. Its condition reflects, often quietly yet precisely, the balance between biological, environmental and behavioural factors, from hydration and micronutrient availability to stress, lifestyle and overall wellbeing.

Awareness of this interconnection is steadily growing among consumers, and the concept of skin nourishment is playing an increasingly prominent role in the beauty and personal care sector. According to recent market insights, consumer interest is shifting towards products designed to nourish, protect and support long-term skin health, gradually moving beyond approaches centred on quick fixes or superficial correction[1].

This shift reflects a broader transformation in the very concept of cosmetics: from products primarily associated with decoration or the treatment of isolated concerns, to functional systems – often rooted in natural origin – designed to strengthen the skin and support its biological processes. Today, beauty routines no longer respond solely to aesthetic needs, but are increasingly part of more conscious self-care practices, where ingredients are expected to work in harmony with the skin’s ecosystem while also ensuring transparency, safety and environmental responsibility.

Skin’s essential nutrients
Skin health depends on a wide range of essential compounds – including fatty acids, vitamins, antioxidants, minerals, amino acids and plant-based phytonutrients – that help maintain its structure and support its core functions. These nutrients play a key role in preserving barrier integrity, promoting cellular renewal, protecting against oxidative stress and supporting a balanced skin microbiome.

The skin receives this nutritional support through two complementary pathways. On one hand, topical skincare works directly on the skin’s surface, helping reinforce the barrier and support the microbiome from the outside in. On the other, nutrition, hydration and – where appropriate – supplementation contribute from within, providing the systemic support needed for long-term skin function and resilience.

While not every nutrient consumed reaches the skin in equal measure – as the skin is not considered a metabolically prioritised organ – adequate nutrition remains essential to support regeneration, antioxidant defence and overall skin vitality. Together, these two dimensions reflect a broader reality: skin health is closely linked to the condition of the body as a whole, and consumers are increasingly aware of that connection. Research suggests, for instance, that 86% of Indian adults believe a healthy diet contributes as much to skin appearance as cosmetic products[2].

This growing awareness also aligns with the rise of skinimalism, a more selective and intentional approach to skincare that favours fewer, more targeted products. Consumers are increasingly drawn to multifunctional formulations[3] enriched with nutrient-dense botanical ingredients, capable of delivering visible results while respecting the skin’s natural balance.

Nature as a source of skin nutrients
Nature offers an extraordinary diversity of ingredients rich in skin-beneficial nutrients, many of which show a strong natural affinity with the skin. Among lipids, plant oils such as borage and evening primrose – naturally rich in omega-6 fatty acids – are well known for their soothing and calming effects on sensitive or reactive skin[4][5]. Rosehip and hemp oils, thanks to their balanced profile of omega-3 and omega-6 fatty acids, support skin regeneration, elasticity and barrier function[6][7]. Plant butters such as mango and marula provide nourishing lipids that help restore softness while maintaining a smooth and comfortable skin feel[8][9].

Alongside oils, botanical extracts represent a valuable source of vitamins, polyphenols and phytonutrients that support the skin’s defence against environmental stressors. Ingredients such as oat, pomegranate, green tea and Centella asiatica are widely recognised for their nutritional richness and well-documented dermatological benefits.

One of the key strengths of natural ingredients lies in the presence of nutrients within complex botanical matrices, which enhance skin affinity and enable more targeted biological activity. The naturally occurring combinations of fatty acids, carotenoids, vitamins and polyphenols can generate synergistic effects that differ from those of isolated synthetic compounds[10].

Some botanical extracts are supported by particularly strong scientific evidence. Pomegranate extracts, rich in polyphenols such as punicalagins and ellagic acid, have demonstrated in preclinical and clinical studies the ability to reduce UV-induced oxidative stress and support barrier function, contributing to greater resilience against erythema and photodamage[11][12]. Green tea polyphenols, especially catechins such as EGCG, have been widely studied in both topical and oral applications, showing benefits in reducing photoageing and inflammatory processes[13]. Centella asiatica, due to its triterpenes such as madecassoside and asiaticoside, is known for its role in supporting collagen synthesis, skin repair processes and soothing effects[14]. Carrot and cranberry extracts, rich in carotenoids and polyphenols, provide additional antioxidant potential and support skin integrity[15]. Oat extracts, thanks to beta-glucans and avenanthramides, contribute to soothing irritation and supporting barrier repair[16]^,[17].

A growing area of interest is also marine and coastal botanicals, including brown, red and green algae. These ingredients provide unique profiles of pigments such as fucoxanthin, phlorotannins and chlorophylls, alongside polysaccharides and carotenoids. In topical formulations, they show antioxidant, anti-inflammatory and photoprotective activity, with emerging evidence supporting their role in hydration and in preventing visible signs of ageing[18].

Finally, as research on the skin microbiome and fermented actives advances, increasing evidence highlights the benefits of probiotics, prebiotics and postbiotics in skincare. These compounds can help modulate the skin microbiome, support natural barrier defences and promote local immune balance[19]. Fermented extracts, rich in bioactive metabolites, may also enhance nutrient bioavailability while offering antioxidant, soothing and regenerative properties, opening new pathways for functional dermocosmetic innovation[20].

Science, safety and authenticity: the NATRUE approach
While interest in natural and organic cosmetics remains stable, consumers have become far more discerning. They increasingly scrutinise ingredient lists, sourcing practices and environmental claims, demanding evidence rather than marketing language. Recent research shows this appetite for trustworthy guidance is growing, with 54% of Italian adults saying they would use an AI tool to help them discover natural or organic products[21].

In this context, the NATRUE Label offers clarity and reassurance for both consumers and manufacturers. Its rigorous criteria ensure that certified products contain natural, derived-natural or organic ingredients, and exclude misleading claims or practices. By promoting transparent labelling, responsible sourcing and verifiable standards, NATRUE helps both brands and consumers navigate a crowded marketplace with confidence.

Seasonal skin nutrition: adapting the skin to its environment
The skin’s nutritional needs fluctuate throughout the year, influenced by climate, lifestyle, and environmental stressors. During winter, the skin often requires lipid-rich formulations and antioxidant support to combat dryness, wind exposure, and reduced humidity. Summer care, on the other hand, emphasises hydration, soothing ingredients, and protective antioxidants that help reduce damage triggered by UV radiation.

Seasonal botanical commonly used in skincare include shea butter, oat and calendula extracts for winter comfort, and aloe vera, cucumber extract, and green tea for summer vitality. A comprehensive approach to skin nutrition combines topical products with a balanced, seasonal diet, adequate hydration, and habits that support overall wellbeing.

Looking ahead: from “skin nutrients” to “skin resilience”
The evolution of skin nutrition is leading towards a new frontier: skin resilience. Future formulations will increasingly rely on biomimetic components, natural ferments, and microbiome-friendly prebiotics that reinforce the skin’s adaptive capacity. At the ingredient level, sustainable innovation – from low-impact extraction methods to upcycled botanical actives derived through upcycling processes – is helping to maximise nutrient availability while minimising environmental footprints.

Ultimately, the future of beauty appears to be shifting towards nourishing and strengthening the skin, rather than focusing on short-term correction alone. In a context where consumers are seeking products aligned not only with their physiology but also with their values, nutrient-rich natural cosmetics supported by credible certification standards such as NATRUE are set to play a central role in shaping a more transparent, ethical and wellbeing-oriented beauty landscape.
