Introduction

Nutricosmetics are dietary supplements formulated to support the health and appearance of the skin, hair, and nails from within. They are commonly used to address concerns such as hair thinning, brittle nails, and early signs of skin ageing by providing nutrients that contribute to normal physiological processes involved in maintaining healthy skin, hair, and nails [4][5].

This report reviews the scientific evidence supporting a comprehensive vitamin and nutrient regimen containing zinc, Fucus vesiculosus, Triticum aestivum, Urtica urens, Arctium lappa, bamboo-derived silica, Viola tricolor, vitamin C, citrus bioflavonoids, vitamin E, beta-carotene, biotin, selenium, Vaccinium myrtillus extract, grape seed extract, pine bark extract, calcium, manganese, copper, olive extract, green tea extract, lutein, collagen, hyaluronic acid, coenzyme Q10, and keratin. Together, these ingredients provide nutritional support for maintaining healthy skin, hair, and nails.

Comprehensive Supplementation for Hair, Skin, and Nails

A growing body of clinical research demonstrates that multi-ingredient nutritional supplements can improve several aspects of skin, hair, and nail health.

A randomized, double-blind, placebo-controlled clinical trial involving 105 participants (97 completed the study) evaluated a plant-based supplement containing biotin derived from Sesbania grandiflora and a biotin-silica complex derived from Bambusa arundinacea. After 90 days of supplementation, participants receiving the biotin-silica formulation experienced significant improvements compared with baseline.

Hair loss decreased to 15.71 ± 10.8 hairs (p < 0.001), while the hair growth rate increased by 0.57 mm/day (p < 0.0001). Nail roughness was significantly reduced to 0.06 ± 0.25 (p < 0.0001), and skin elasticity improved to 0.17 ± 0.12 (p < 0.0001), demonstrating measurable benefits for multiple aspects of appearance [1].

Similar findings were reported in a 90-day observational study involving 30 participants (mean age 36.9 ± 9.2 years) who consumed a plant-based supplement containing 10,000 mcg biotin, collagen peptides, vitamin C, glycoproteins, and amino acids.

The study reported:

• a 99% reduction in hair loss,
• a 30-unit increase in hair density,
• a 40% improvement in nail growth,
• a 31.11% increase in skin hydration,
• an 18.12% increase in skin elasticity, and
• a 19.19% reduction in wrinkle length after 90 days of supplementation [2].

Another clinical investigation evaluated a nutritional supplement formulated with peptides, lipids, collagen, and hyaluronic acid, administered orally once daily as a 20-gram dose.

After 8 weeks, statistically significant improvements were observed in:

• nail cracking,
• brittle nails,
• dull hair,
• dry hair, and
• dry skin.

A subsequent 60-week crossover study demonstrated that these benefits could be maintained for up to 52 weeks. Among participants with severe symptoms:

• 95% experienced significant improvement in dry and dull hair,
• 85% showed improvement in nail splitting and peeling, and
• 65% demonstrated improved nail hardness [3].

These findings suggest that comprehensive nutritional supplementation can provide measurable improvements across multiple parameters of skin, hair, and nail health when used consistently over time.

Specific Micronutrients and Their Roles

Biotin

Biotin is an essential water-soluble B vitamin that serves as a cofactor for several carboxylase enzymes involved in energy metabolism, fatty acid synthesis, and amino acid metabolism. It also plays an important role in the growth and maintenance of keratinocytes and hair follicle cells, making it an important nutrient for healthy hair and nails [1][6].

Biotin deficiency has been associated with dry skin, seborrheic dermatitis, impaired nail growth, brittle nails, and hair loss [6][7]. Scientific studies further suggest that biotin may regulate growth factor signalling pathways involved in stem cell activation, thereby supporting hair follicle viability and promoting healthy hair growth [6].

Zinc

Zinc is an essential trace mineral with well-established antioxidant and immunomodulatory properties. It contributes to numerous biological processes involved in maintaining healthy skin, hair, and nails and has been investigated extensively in dermatology [8].

Clinical evidence supports the use of zinc in various hair loss disorders, where adequate zinc status may contribute to improved hair growth and reduced hair shedding. Some studies have also reported potential benefits for conditions such as alopecia and hirsutism [8][9][10].

Collagen and Hyaluronic Acid

Collagen is the primary structural protein of the skin and contributes to skin firmness and elasticity. Oral supplementation with hydrolysed collagen, particularly when combined with vitamins and other supportive nutrients, has been shown to increase circulating collagen-derived peptides, which may support collagen synthesis and improve skin quality [11].

Hyaluronic acid plays a complementary role by helping maintain skin hydration and elasticity. Clinical studies have demonstrated that supplementation with collagen and hyaluronic acid can improve skin appearance while also supporting stronger nails and healthier hair [3][11].

Vitamins C and E, Selenium, and Beta-Carotene

Oxidative stress and ultraviolet (UV) exposure contribute to premature skin ageing and may negatively affect hair health. Antioxidants such as vitamin C, vitamin E, selenium, and beta-carotene help protect cells from oxidative damage and support the skin's natural defence mechanisms [12][13].

Vitamin C is particularly important because it contributes to normal collagen formation, an essential component of healthy skin. Research also suggests that vitamin C, when combined with antioxidants such as vitamin E and selenium, may work synergistically to reduce lipid peroxidation in the skin, a process associated with skin ageing and certain hair disorders [11][13].

Beta-carotene additionally possesses antioxidant properties and has been reported to exhibit insulin-sensitising effects in certain clinical settings [10].

Silica

Silica, particularly when derived from bamboo extract, is commonly included in nutricosmetic formulations because of its proposed role in supporting collagen synthesis and maintaining connective tissue integrity.

Clinical research has demonstrated that supplementation with biotin combined with bamboo-derived silica contributes to improvements in hair growth, nail quality, and skin elasticity, suggesting that silica may support the structural components of healthy skin and hair [1].

Botanical Extracts and Additional Nutrients

Several additional botanical extracts and nutrients included in the Beauty Card—including Fucus vesiculosus, Triticum aestivum, Urtica urens, Arctium lappa, Viola tricolor, citrus bioflavonoids, Vaccinium myrtillus extract, grape seed extract, pine bark extract, olive extract, green tea extract, lutein, coenzyme Q10, keratin, calcium, manganese, and copper—are frequently incorporated into nutricosmetic formulations because of their nutritional and antioxidant properties [4][5][9].

Although the scientific literature provided does not include studies evaluating this exact combination of ingredients in a single formulation, many of these individual components are recognised for supporting normal skin function, protecting against oxidative stress, or contributing to the maintenance of healthy connective tissues, hair, and nails.

Conclusion

The available scientific literature supports the use of comprehensive nutritional supplementation for promoting healthy skin, hair, and nails.

Ingredients such as biotin, silica, collagen, hyaluronic acid, zinc, vitamins C and E, selenium, and other antioxidants have demonstrated beneficial effects across multiple clinical studies. Reported improvements include substantial reductions in hair loss (up to 99%), increased hair growth rate (up to 0.57 mm/day), stronger and faster-growing nails (up to 40% improvement), and measurable enhancements in skin hydration and elasticity, together with reductions in visible signs of skin ageing [1][2][3].

While the specific combination of ingredients included in the Beauty Card has not been directly evaluated in the available scientific literature, the individual ingredients are supported by evidence demonstrating their contributions to maintaining healthy skin, hair, and nails. Their complementary mechanisms of action suggest that a multi-ingredient nutritional approach may provide broad support for dermatological health and overall appearance.
