Clinically validated and proven to be effective across all skin types, Belight3™ is both science-backed and highly appreciated by consumers, positioning it as a compelling inside-out solution in the growing skin-brightening category.
A study in Frontiers in Psychology shows that even skin tone is subconsciously linked to health, youth and attractiveness.
Yet hyperpigmentation — such as age spots and melasma — affects more than half the population, especially those older than 50.1
In addition, a real-world study by Activ’Inside found that 78% of people are bothered by uneven skin tone, highlighting the growing demand for effective solutions.
With the hyperpigmentation market valued at $1.39 billion in 2024 and growing, consumers are turning to nutricosmetics for gentler, inside-out approaches that reflect modern wellness values.2
Today, even skin isn’t a luxury; it’s a priority. Belight3 answers this demand.
Developed by Activ’Inside, this patented ingredient effectively addresses the biological roots of pigmentation problems with a unique blend of natural actives to deliver visible and clinically validated results.
A powerful blend of four natural ingredients
Selected based on their scientifically proven actions on melanin regulation and skin protection, Belight3 features four synergistic compounds.
- Grape seed extract (from Champagne, France): rich in flavanol monomers, it is a powerful antioxidant that reduces tyrosinase activity and UV-induced melanin overproduction.3
- Liquorice root extract: a traditional skin-brightening agent backed by research for its tyrosinase-inhibiting properties and defence against oxidative stress and UV damage.4
- Grape pomace extract: sourced from French vineyards, it contains viniferin, a potent antioxidant that’s known to brighten and even out skin tone.5
- Vitamin C: a well-established skin-brightening antioxidant that inhibits tyrosinase and supports collagen synthesis.2
How it works: targeting the root causes
Melanin production or melanogenesis occurs in melanocytes and is catalysed by the enzyme tyrosinase, which converts tyrosine into melanin.
This process is intensified by UV radiation, oxidative stress and ageing, leading to dark spots and an uneven complexion.6
Belight3 acts through three key mechanisms:
- regulation of tyrosinase activity to limit excess melanin synthesis
- antioxidant action to reduce oxidative stress‑induced pigmentation
- photoprotection to shield skin from UV‑triggered damage.
In vitro studies have confirmed that each ingredient individually inhibits tyrosinase. When combined, they deliver a synergistic effect to achieve 85% inhibition of the enzyme responsible for excess melanin production (Figure 1).5
Clinically proven results across all skin types
In a real-world study conducted in France with 100 participants, daily supplementation with 300 mg of Belight3 for 2 months led to a 30% reduction in age-related dark spots and a 40% decrease in sun-induced pigmentation.
Improvements were visible after just 11 days, on average, with 82% expressing overall satisfaction with the results at the end of the trial.7
A randomised, placebo-controlled trial in Bangkok evaluated the effects of Belight3 on 58 Asian participants (phototypes III–IV). After 3 months, participants showed significant improvements in skin brightness and the reduction of dark spots compared with a placebo, demonstrating the formula’s efficacy even in sun-exposed, polluted environments.5
A second clinical study, conducted in winter in two northern Italian cities, involved 66 Caucasian participants (phototypes I–III). After 12 weeks, participants experienced a 22.4% increase in ITA°, a skin brightness index, confirming a visible lightening of dark spots (Figure 2).
In addition, more than 70% of the subjects showed dermatologically confirmed improvements.8
Recognised in the US market with structure/function claims
Supported by a reputable US law firm, Belight3 has recently received approved structure/function claims in the United States.
This milestone, grounded in the strength of its dual clinical validation, sets Belight3 apart from other nutricosmetic ingredients. Claims such as “Belight3 evens skin tone” and “Belight3 helps to reduce dark spots by regulating melanin production” are now available for use in the US market, reinforcing Belight3’s credibility and global positioning.
Sustainable, inclusive and high-quality
Belight3 reflects strong environmental and ethical values (Figure 3), such as
- made from upcycled grape by-products to support the circular economy
- sourced in France under strict EU safety and quality standards
- free from allergens, pesticides and contaminants
- certified for vegan, Halal and Kosher use.
Its versatility makes it ideal for capsules, gummies or as part of a custom nutricosmetic blend.
Conclusion
Clinically validated for a variety of skin types and conditions, Belight3 is a natural and powerful ingredient that effectively reduces dark spots and promotes even, radiant skin.
Its efficacy is not only backed by science but is now also supported with US structure/function claims, enabling brands to communicate clear, compliant benefits to consumers.
Combined with a sustainable sourcing model and inclusive formulation options, Belight3 stands as a versatile and trusted solution for the future of beauty-from-within.
