For generations skincare, particularly sun protection, was something we equated with protective clothing or lotions – both worn on the body’s exterior. Today however, a growing philosophy in the nutraceuticals industry, particularly those who work with cutting-edge skincare brands, suggest that ingestible skincare is the future in combination with topical protection.
The notion of swallowing a capsule and protecting yourself from solar damage shouldn’t seem that far-fetched. Research and technology is already in the marketplace supporting the viability of such products, and products like Lyc-O-Derm™, available through medical practitioners but not over the counter yet, offer consumers just such a complementary approach to protect from the sun’s harmful rays.
Two of the most prominent ingredients that make ingestible skincare viable are the tomato extract and carnosic acid extracted from the herb, rosemary. Properly formulated, this blend supports skin health and offers protection from both UVA and UVB damage.
Lyc-O-Derm offers a dietary approach based on UV absorption over a broad range of wavelengths and on intracellular control of oxidative stress, signaling and inflammation for a continual intracellular photoprotection.
Recent studies suggest that tomato-extract based drink fortified with phytoene and phytofluene over a 12 week period could reduce erythema – skin redness caused by sun exposure – by 48% .
A significant correlation was found between forehead skin roughness and lycopene concentration in the skin of 40- to 50-year-old men and women . The molecular mechanism of this effect includes a decrease in the expression of MMPs; for example, tomato paste supplementation decreased the expression of MMP1 in buttock skin of healthy women .
Moreover, in a clinical study performed by LycoRed, supplementation with tomato extract capsules (10 mg lycopene/day), not only reduced levels of MMP1 mRNA (a marker of photo-aging) in healthy individuals, but also reduced the expression of other molecular markers of UV damage such as the Inter Cellular Adhesion Molecule 1(ICAM1), a marker for skin inflammation .
The common cooking herb rosemary, native to the Mediterranean, has enormous potential for use in sun protections supplements. The plant leaves contain high amounts of phenolic diterpenes such as carnosol and carnosic acid. These compounds display antioxidant and anti-inflammatory effects in vitro [2, 8, 20].
The implications for the skincare and beauty industries are significant. Already a years long shift toward more holistic and organic skincare had seen a rise in new products that speak to educated, passionate consumers looking for natural options. The nutraceuticals industry and industry leaders like L’Oreal and Sanofi are steadily reshaping the approach to skincare and sun protection through the development and incorporation of nature-based technologies, and Lyc-o-Derm is just one pioneering product in this trend.
