Beauty-From-Within Category Gets a Makeover

by Brenda Porter-Rockwell | September 1, 2026

Focus moves onto new science-backed ingredients that connect overall wellness and beauty needs.

Collagen and biotin may still anchor the beauty-from-within aisle, but the opportunity to innovate with new and specialty ingredients is expanding quickly. Today’s consumers are looking for clinically validated, multi-functional and personalized solutions that support hair, skin and nails from the inside out.

As one of the fastest-growing segments in the natural products sector, the U.S. beauty supplement market was expected to top more than $1 billion in 2025, according to market research firm Kline + Company’s (Parsippany, NJ) 2025 Beauty Nutrition: U.S. Market Brief.

From gummies and powders to capsules and drops, the category is opening new pathways for brands to deliver science-backed beauty benefits in formats consumers already enjoy. Here are the biggest trends shaping the hair, skin and nails market.

Beauty-from-Within Grows Beyond (and Beside) Collagen

In 2025, research firm MarkNtel Advisors (India) valued the U.S. collagen supplement market at $426 million and projected the category to reach $608.56 million by 2032. Clearly, collagen is still king, but it’s got new subjects.

The category is still built around collagen, but brands are increasingly pairing familiar ingredients with complementary actives that address skin, hair, nails and broader wellness goals at the same time.

Newer ingredients in the category include multi-collagen peptide blends, ceramides for skin barrier support, hyaluronic acid for hydration, vitamins C and E to support collagen synthesis and astaxanthin and other antioxidants for improved skin moisture and elasticity.

“Consumers may be willing to experiment with novel ingredients, but collagen peptides remain a category leader because they deliver benefits consumers can see and understand, supported by a growing body of clinical evidence,” said Angie Rimel, marketing communications manager at GELITA (Sergeant Bluff, IA).

Rimel pointed to three trends driving sustained demand for established ingredients such as collagen peptides, which combine visible beauty benefits with clinical support:

1. Consumers increasingly see a connection between nutritional health and appearance, particularly as they focus on healthy aging and long-term wellness.

2. Beauty is becoming more intricately linked with confidence, self-care and overall wellbeing. 3. Consumers are demanding clinically substantiated ingredients that deliver measurable results. The move toward combination formulas will be an opportunity to further innovate in the collagen category.

Rather than replacing trusted ingredients, Leslie Lannebere, global marketing manager-health division, Nexira (France), the supplier sees innovating with collagen as complementary.

“Collagen continues to be one of the most trusted ingredients in the beauty-from-within category because consumers understand its role in supporting skin structure and healthy aging,” said Lannebere. “However, today’s consumers are looking beyond a single ingredient. They want comprehensive solutions backed by clinical science and designed to address multiple aspects of skin health.”

Nexira is also formulating with a collagen combination with its upcycled olive fruit extract rich in hydroxytyrosol and polyphenols called Oli-Ola.

This approach, Lanneberre said, allows product partners to develop those sought after next-generation beauty solutions that combine consumer familiarity with scientifically validated innovation.

“Formulating products with multiple ingredients that work synergistically—like elastin alongside collagen and hyaluronic acid—can give brands a real point of differentiation” said Hannah Lee, internal sales and marketing manager for California-based ingredient supplier JBSL-USA.

Rajat Shah, co-founder of India-based Nutriventia, said consumers are more curious than ever about what may work better for them as an individual rather than as one of the masses. Shah highlighted data sourced from Nutrition Business Journal, which like Klein + Company, placed the beauty-from-within category at $1 billion-plus in 2025, growing 2.6 percent CAGR, with acceleration toward 5 percent in 2026.

Thus, she said, beauty-from-within, “Isn’t a category exploding in dollars.”

But what has changed is the category composition.

“Spend is moving away from generic glow positioning and toward actives with human data behind them,” Shah said. “Consumers now understand that topicals only reach the outermost skin layers, and they’ve been disappointed often enough to start asking how a product performed in a trial rather than what it promises on the front of pack. The label scrutiny that started in food has arrived in beauty.”

TurmXTRA glow, Nutriventia’s turmeric-based ingredient, was born from that same instinct to question though the origin was accidental. According to Shah, a steady number of consumers taking TurmXTRA for joint comfort reported that their skin looked better.

From there, Nutriventia conducted a randomized, double-blind, placebo-controlled trial in 96 healthy women aged 18 to 40 and published it in the Journal of Cosmetic Dermatology. From there Nutriventia began to see TurmXTRA glow in a new light.

However, as a newcomer to the category, Shah said TurmXTRA glow does not aim to replace mainstays like collagen and biotin. Instead, turmeric is better placed near such well-known options.

“We don’t try to displace biotin or collagen. We sit next to them, and we’re specific about where,” said Shah.

She said the conversation with a brand isn’t anchored on “better than collagen.” It’s “what is this product for?”

“If the answer is clarity, hydration and radiance rather than fine lines, turmeric has a case in the formula. And usually alongside those ingredients rather than instead of them,” Shah said.

Targeting the Root Causes of Beauty Concerns

Today’s modern consumer is more health conscious than vain. They are not looking for talking points. Instead of promising generic phrases like “better hair” or “younger skin,” consumers are looking for brands to better engage them in addressing the biological drivers behind conditions like aging and hair loss.

Consumers now recognize that poor sleep, stress, nutrient deficiencies and metabolic health directly affect hair, skin and nails. Emerging areas of science for the beauty-from-within category include gut microbiome support and cellular health and longevity, for example.

Rimel said today’s consumers want nutritional solutions that support visible benefits that complement broader wellness goals for healthy aging and self-care. Increasingly, consumers are seeking products that are precise, proven and backed by science rather than relying on one-size-fits-all beauty claims.

“As the category matures, the conversation has shifted from simply ‘using collagen’ to selecting collagen ingredients with proven efficacy, targeted functionality and scientific substantiation. That differentiation is helping collagen peptides remain one of the most trusted and enduring ingredients in the beauty supplement market,” said Rimel.

GELITA’s VERISOL is a bioactive peptide profile designed to stimulate fibroblasts, the skin cells responsible for producing collagen, elastin and hyaluronic acid. Converting the body’s natural collagen metabolism from within, VERISOL helps improve skin elasticity, hydration, reduced wrinkle appearance, increased hair thickness, and stronger nails.

Vidya Herbs USA’s (Bunnell, FL) Biotical line of ingredients targets beauty-from-within by combining botanical ingredients with probiotics for gut microbiome health. The Biotical innovation leverages the growing gut-axis research which seems to indicate a correlation between gut health and other regions of the body.

Biotical-GS targets the gut-skin axis for skin health and Biotical-GH targets the gut-hair axis for hair health. Kūlaris, another blend of Vidya’s Skin-Cera with a guggul extract specifically aimed at improving the appearance of skin blemishes.

Sustainability as the Norm More Than the Exception

Consumers are seeking effective ingredients that are sustainable and environmentally responsible. Their purchasing power must match their values.

“Sustainability has moved from a differentiator to an expectation with many consumers across every category, including beauty and wellness,” said Biova (Johnston, IA) President Amanda Jepson. “People today are looking for products that deliver measurable results while also reflecting their values.”

For example, Biova’s 100 percent upcycled eggshell membrane is recovered from the food production stream and transformed into natural ingredients instead of becoming waste.

Brands have responded to the consumer demand for sustainable ingredients by combining trusted ingredients like collagen with newer natural and plant-derived ingredients.

Biova offers a combination of naturally occurring collagen, elastin and glycosaminoglycans, alongside a circular, resource-efficient sourcing model that resonates with environmentally conscious consumers.

For Nutriventia, sustainability is built into their supply chain.

“Our strongest sustainability argument is arithmetic,” said Shah.

At 250 mg against 1,500 to 2,000 mg for a standard extract, roughly six to eight times less material moves through the system for the same daily serving. That means less rhizome, less extraction throughput, less capsule volume, less packaging, less freight, she said.

“And because the delivery platform removes the need for piperine, there’s no second sourced botanical sitting behind it. Dose efficiency is material efficiency, and it’s measurable,” Shah added.

She said Nutriventia works with backward-integrated supply partners drawing from smallholder farms in India’s principal turmeric regions. The farms maintain end-to-end batch documentation, which Nutriventia’s quality system validates through routine online and on-site audits. Additionally, its TurmXTRA glow is Clean Label Project Certified.

Beyond sustainably sourced ingredients like its Oli-Ola, Nexira engages in sustainable development practices, including measuring greenhouse gas emissions from its home and foreign offices and all manufacturing sites since 2009.

Clinical Evidence Matters More Than Marketing

Ingredient innovation beyond collagen and biotin is also being driven by better-informed consumers who can fact-check claims instantly. As consumers increasingly connect beauty with overall health—not appearance alone—clinical substantiation is becoming a key purchase driver. They are paying closer attention to dosages and seeking products backed by science.

Ingredients such as collagen peptides, ceramides and hyaluronic acid are supported by research tied to outcomes such as skin hydration and elasticity.

“With the growing demand for natural beauty ingredients in the market, ingredients that will differentiate themselves from the rest are those with research-backed results,” said Lee.

Lee pointed to one emerging category: formulas for people using GLP-1 weight loss drugs. These consumers may benefit from skin health supplements that address loose or sagging skin associated with rapid weight loss.

Lee cited three skin health studies showing Elastin-F’s efficacy in improving skin elasticity and overall skin condition, including texture, wrinkles and hydration. She added that Elastin-F also has a human study showing improved skin elasticity in women losing weight through dieting.

Elastin-F also has studies showing a traceable mechanism of action. Lee attributed this to Pro-Gly, a unique bioactive peptide detected in the bloodstream after Elastin-F ingestion and confirmed through a pharmacokinetic study.

In vitro, Pro-Gly has been shown to significantly enhance elastin synthesis in human skin fibroblasts, rather than stimulating fibroblast proliferation, which is associated with collagen peptides.

Vidya works with a leading industry law firm to review data on its clinically studied products and develop opinion letters for specific materials.

Christopher Bailey, PhD, director, technical business development at Vidya, said these opinion letters include potential structure/function claims and summaries of the clinical data supporting them. That helps brand partners better understand how to position the product in new formulations.

“Vidya prides itself on an ever-expanding library of ingredients backed by human clinical trials that support the internal beauty health benefit category,” said Bailey.

Vidya has also developed multiple grades of Skin-Cera, its ceramide extract for skin health, to support different finished-product price points. Each grade has its own clinical trial supporting structure/function claims.

That demand for substantiation is also expanding what counts as credible research. Beyond showing how an ingredient works, suppliers say studies increasingly need to reflect the diversity of the consumers who will use beauty-from-within products.

“Inclusivity should begin in research, not only in communications. Skin and hair biology are influenced by sex, age, hormonal status, ethnicity, skin phototype, lifestyle, diet, geography and environmental exposure,” explained Violetta Insolia, business development and marketing manager for Italy-based Bionap. “Therefore, the development of nutricosmetic solutions should avoid the assumption that one beauty model, one endpoint, or one consumer profile applies to everyone.”

Bionap’s beauty-from-within clinical research has increasingly included participants with diverse skin phototypes and ethnic backgrounds in recent years, reflecting a broader view of substantiation that considers who is represented in the data as well as what outcomes are measured.

“The objective is not simply to make studies more representative, but to understand whether and how an active ingredient may perform differently across populations. We believe this is a fundamental part of the scientific robustness of an ingredient” said Insolia.

As ingredient options and clinical claims become more sophisticated, suppliers also face a communication challenge: helping consumers understand what differentiates one formulation from another. That has pushed companies to pair substantiation with clearer storytelling, especially when explaining ingredient origin, sustainability and targeted benefits.

“By combining scientific validation with a compelling sustainability story, we help consumers recognize that BiovaBIO and BiovaDerm offer a differentiated approach to beauty support rather than another me-too ingredient,” said Jepson.

Bionap, a supplier of Mediterranean botanical extracts from plants and fruits, also emphasizes the role of storytelling in helping brands connect science, provenance and consumer relevance.

“Bionap works closely with manufacturers to bridge the gap between Mediterranean tradition and modern consumer health needs,” said Insolia. “By providing scientific substantiation and technical support, the company helps partners understand the unique value of botanicals sourced from Sicily and the broader Mediterranean region.”

Whether highlighting blood oranges or prickly pear, Insolia said Bionap helps partners communicate an ingredient story that connects provenance, sustainability and clinically supported benefits.

Personalized & Life-Stage Beauty Nutrition

As brands target needs such as healthy aging, GLP-1 medication-related hair thinning and sagging skin, the market is expected to move beyond generic hair, skin and nail formulas toward products tailored to consumers’ individual health needs.

The shift reflects rising demand for precise, personalized nutrition, with consumers seeking diverse products aligned with their life stage and health priorities.

Rimel predicts that hair, skin and nail products will face increasingly pharmaceutical-grade expectations, including stronger clinical substantiation, greater transparency and measurable outcomes.

“The future will be precise, proven and personalized, with consumers seeking targeted solutions tailored to their needs rather than one-size-fits-all approaches,” said GELITA’s Rimel.

“As a result, science-backed ingredients with demonstrated efficacy, such as bioactive collagen peptides, are well positioned at the intersection of beauty, wellness and healthy aging.”

Trends such as collagen blends align with Nexira’s Lannebere’s view that multifunctional ingredients addressing multiple health attributes will gain traction. Like Rimel, Lannebere said clinical evidence will be essential.

“As consumers become more informed, brands will increasingly rely on ingredients supported by robust human studies and clear mechanisms of action. We believe the future belongs to scientifically validated natural ingredients that combine efficacy, sustainability and holistic wellness,” Lannebere said.

For Insolia, sustainability and clean label principles will shift from market differentiators to baseline expectations as consumers look for products that reflect their values.

“Consumers are interested not only in what is in their products, but also where ingredients come from, how they are produced, how effective they are and their overall environmental impact,” said Insolia.

She said demand will grow over the next five years for responsibly sourced, sustainable ingredients backed by transparent supply chains.

“Companies will be expected to show a commitment to reducing waste, lowering their carbon footprint and embracing circular economy practices throughout product development,” said Insolia.

Vidya’s Bailey also expects sustainability to become more important, yet the beauty-from-within category could shift to new sales channels. He said many cosmetic products can offer meaningful benefits, but treatments such as chemical peels, including glycolic, salicylic and lactic acids, or retinoids such as retinol, can be harsh on the skin. And that’s an area where natural ingredients for hair skin and nails can be strongly positioned in new ways. “We see a future where dietary supplements work alongside cosmetics,” Bailey said.

According to Lee, meeting consumers’ varied lifestyles will become increasingly important, with products available wherever consumers need them—on the go, in the car or at the gym.

“As beauty-from-within ingredients become more popular in formats such as creamers, coffees, teas, foods, gummies and more, ease of formulation will be increasingly important,” said Lee.

Finally, Jepson predicts that as consumers take greater ownership of their skin health and wellness, ingredients that combine science, transparency and environmental responsibility will continue to gain momentum. NIE
