The growing convergence of beauty and wellness—alongside consumers’ increasing awareness that internal nutrition affects skin, hair and nail health—continues to establish beauty from within as a category of its own within the beauty industry.
At the recent In-Cosmetics Global 2025 show in Amsterdam, we hunted down the latest ingredients innovation in this space.
High-purity microalgae made using solar power
British-Portuguese company Arborea has created ultra-sustainable technology that makes nutricosmetic ingredients and natural colors from carbon dioxide.
Using its Biosolar Leaf technology, which is powered by sunlight, it transforms carbon dioxide emitted from industry into eco-friendly, high-purity microalgae-based ingredients. By using this system, it does not need fertile farmland and thus helps to prevent deforestation and protect biodiversity.
Dr. Kaly Chatakondu, global commercial director at Arborea, noted that algae is a superfood rich in bioactive nutrients that can be used for supplements, as well as cosmetic ingredients because the skin is the largest organ of the body.
Wheat-based ceramides
Multifunctional Newonat Wheat Ceramides Powder can be used in cosmetics for its moisturizing, anti-elastase, anti-free radical and restructuring actions and or in nutricosmetics to soothe very dry skin and offer anti-aging skin benefits.
According to Newonat, numerous clinical studies showed an improvement in dry skin conditions thanks to the inclusion of wheat ceramides.
Skin-brightening rose and melon mix
Robertet’s Damastyl is an ingestible derived from Damask rose and cantaloupe melon that claims to brighten and even out skin tone, as well as confer antioxidant benefits, according to the French natural ingredients company, which has been increasingly innovating in the nutricosmetics sector in recent years.
Robertet referenced four advanced oral clinical studies on over 160 women showing that the ingredient “significantly increases the antioxidant power of the skin and the beauty benefits this brings.”
According to Irène Lamour, Robertet’s nutricosmetics marketing and sales director, there is a growing demand for these kinds of beauty-from-within ingredients in the skin care category.
Lamour said the ‘interior beauty market’ is “worth $7.5 billion and forecasted to grow by more than 6% a year.”
“Demand is driven by research into more holistic skin care,” she said. “The development of scientific innovations in applications and the proof of efficacy provided by placebo-controlled clinical studies are boosting consumer interest in ‘beauty from within’.”
She also noted that “consumers are looking for ingredients that reassure them, that speak to them and for which they can know the origin.”
Pomegranate peel powder
VMP Chemiekontor Ganirin Pomegranate Peel Extract Powder features Ganirin, a botanical extract from peels and meso-carp of selected pomegranates that contains a standard matrix of ellagic acids. These are extremely rich in the phenolic compound punicalagin and the ingredient offers soothing, anti-inflammatory and antioxidant benefits.
As a multifunctional, Ganirin can be used in topical and ingestible beauty from within products.
Digestible and bioactive keratin blend
Keraplast keraGEN-IV is blend of digestible, bioactive keratins that are rich in cysteine/cysteic acid and trigger the production of collagens IV and VII.
According to Keraplast, the beauty-from-within ingredient works synergistically with dietary collagen to boost the body’s ability to produce the right structural proteins to repair wrinkles and strengthen hair follicles and nails.
This is achieved by “activating skin cells with the right nutritional input to specifically make collagen IV and collagen VII, the binding proteins that join the dermal and epidermal layers essential for smooth, wrinkle-free skin as well as anchoring hair follicles into the scalp,” the company said.
Konjac extract
Vidya Europe’s Skincera is made in Japan from extracts of local Amorphophallus konjac (Voodoo lily)—a medicinal food rich in ceramides.
The company said that in vitro studies have demonstrated the ingredient’s ability to preserve the skin’s structural integrity and reduce melanin production. Applied topically, Vidya Europe says it can “improve skin quality and reduce signs of photodamage within 12 weeks,” while as a dietary supplement, it is “effective in reducing skin dryness and dark spots.”
