A Clinically Dosed Carotenoid Complex for Skin Health

Researched & Written by: Kurt Yazici, AS Biology, PreMed, BS Electrical Engineering

Introduction

Carotenoids and antioxidants play a pivotal role in skin physiology, influencing elasticity, hydration, barrier strength, and resilience against oxidative and UV-induced damage. Bronze Bites was formulated with Beta-carotene (8 mg/day), Astaxanthin (4 mg/day), and Vitamin C (100 mg/day) — doses aligned with published human clinical trials. Unlike competing products that rely on overstated claims or unverified ingredient sourcing, Bronze Bites is grounded in peer-reviewed science and supported by third-party verified Certificates of Analysis (COAs).

Beta-Carotene and Skin Health

Beta-carotene, a provitamin A carotenoid, accumulates in the epidermis where it strengthens the skin barrier and provides antioxidant defense. Human trials show that supplementation at 6–9 mg/day leads to measurable shifts in skin carotenoid content and improvements in perceived skin health within 6–12 weeks.

• Skin carotenoid levels: measurable increases within 6–12 weeks (spectrophotometry)
• Barrier protection: ≥6 mg/day in combination with other antioxidants reduced UV-induced erythema
• Nutrient role: converts to vitamin A, supporting epidermal health and renewal
• Bronze Bites Dose: 8 mg/day — positioned at the “sweet spot” for efficacy without risk of hypercarotenemia

Implication: A clinically relevant dose for improved skin appearance and foundational barrier support.

Astaxanthin and Dermal Integrity

Astaxanthin, a marine carotenoid, is one of the most potent antioxidants studied in skin health. In randomized controlled trials, 4–6 mg/day improved hydration, elasticity, and wrinkle appearance within 6–8 weeks.

• Elasticity: significant improvements by week 8 (4 mg/day)
• Wrinkles: reduced wrinkle depth around the eyes in 8 weeks
• Hydration: 18–20% increase in skin moisture retention at 4–6 mg/day
• Photoprotection: increased minimal erythema dose (MED) and reduced oxidative stress
• Bronze Bites Dose: 4 mg/day — matches clinical entry dose

Implication: Baseline clinical efficacy — measurable improvements in hydration, elasticity, and wrinkle depth reduction within 8 weeks.

Vitamin C: Collagen & Antioxidant Synergy

Vitamin C is essential for collagen synthesis, antioxidant protection, and barrier integrity. While high doses (>500 mg/day) are often studied for maximal collagen synthesis, moderate levels enhance carotenoid bioactivity and support overall skin defense.

• Plasma status: 100–200 mg/day maintains optimal vitamin C levels
• Collagen support: enhances fibroblast activity and structural integrity at baseline doses
• Photoprotection: 100–500 mg/day with carotenoids reduces UV-induced erythema and oxidative damage
• Bronze Bites Dose: 100 mg/day — synergistic and supportive within the antioxidant network

Implication: Enhances carotenoid efficacy while providing essential support for collagen and barrier health.

Synergy of the Antioxidant Network

While each nutrient offers benefits individually, their combined effect is amplified. Carotenoids and Vitamin C interact within the dermis to quench free radicals, stabilize collagen, and strengthen the skin barrier. Clinical antioxidant protocols show that multi-ingredient complexes improve elasticity, hydration, and resilience more effectively than single compounds¹⁰,¹¹.

Timeline of Expected Results

• Weeks 4–6: Early improvements in hydration and elasticity (Astaxanthin, Vitamin C)
• Weeks 6–10: Wrinkle depth reduction, smoother texture, improved barrier strength (Astaxanthin + Beta-carotene)
• Weeks 10–12: Stronger photoprotection, reduced UV-induced redness, sustained improvements in skin resilience (all actives combined)

Conclusion

Bronze Bites is the first daily gummy in its category formulated at clinically studied doses for skin health. At 8 mg Beta-carotene, 4 mg Astaxanthin, and 100 mg Vitamin C, it delivers measurable benefits in hydration, elasticity, barrier support, and resilience within 6–12 weeks. By leveraging the synergy of carotenoids and Vitamin C, Bronze Bites supports long-term skin wellness from within, offering a foundational approach to skin health that complements any topical routine.
