Science
Mechanism of Action
Beta-Carotene operates through several key pathways in the skin. As a powerful antioxidant, it neutralizes singlet oxygen and free radicals, protecting cellular structures and lipids within the intercellular matrix from oxidative stress, thereby mitigating premature skin aging and sun damage. In living tissues, it undergoes partial oxidation to retinal, making it a precursor to Vitamin A. This conversion supports increased cell turnover, enhanced collagen synthesis, reduction in the appearance of fine lines, wrinkles, and roughness, and overall cell renewal and healing. Furthermore, it provides photoprotection by reducing UV-induced erythema and aiding in the prevention of certain photodermatoses. CI 75130 also influences melanin synthesis, both preparing the skin for tanning by stimulating melanogenesis and potentially inhibiting melanin production to address pigmentation disorders such as melasma and post-acne discolorations. Studies also indicate its capacity to enhance skin moisture content and exert anti-inflammatory effects by inhibiting key inflammatory mediators like NO, prostaglandin E2, and superoxide dismutase, alongside downregulating iNOS/cox-/NADPH oxidase proteins and mRNA, and suppressing TNF-α.

Key findings
- 01 A single topical application demonstrated a 160-fold increase in β-carotene content in human skin within 24 hours, confirming robust stratum corneum permeation.
- 02 Topical use in an unspecified concentration within vesicles alongside UVA/UVB filters resulted in melasma regression for the majority of 31 patients over an 8-24 week period.
- 03 Oral supplementation exceeding 12 mg/day, maintained for a minimum of 10 weeks, significantly reduced UV-induced erythema, indicating photoprotective capabilities.
- 04 Daily oral supplementation of 24 mg or 30 mg over 10 to 12 weeks substantially lowered skin susceptibility to sunlight, quantified by a reduction in erythema intensity.

The Formula
Formulation
Stability
Beta-Carotene is inherently sensitive to air, heat, and light, exhibiting chemical instability to oxygen and elevated temperatures. This can lead to degradation, diminishing product efficacy and potentially causing undesirable discoloration in the final formulation. Protective packaging and antioxidant co-factors are recommended.
Conflicts
- Highly sensitive to light, heat, and oxygen, requiring careful formulation and packaging to prevent degradation and maintain stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has deferred its evaluation of Beta-Carotene due to prior assessment by the FDA. The FDA sanctions Beta-Carotene as a color additive, exempt from certification, for use in foods, drugs, and cosmetics (including the eye area) in amounts aligned with Good Manufacturing Practices (GMP). Topical cosmetic formulations typically incorporate concentrations from 0.01% to 1%, with observed minimal irritation potential. In the EU, it is sanctioned as a colorant under Annex IV of the EC Cosmetics Regulation.
