Science
Mechanism of Action
Hesperidin operates through several key pathways to enhance skin vitality. It acts as a powerful antioxidant, neutralizing reactive oxygen species to protect skin from oxidative stress and promote radiance. Its anti-inflammatory properties soothe the skin and reinforce the epidermal permeability barrier. By preventing UV-induced lipid peroxidation, it helps mitigate erythema and UV damage. Hesperidin improves microcirculation, aiding in the reduction of dark circles and under-eye puffiness. It also stimulates collagen production for improved elasticity, reduces melanin synthesis by inhibiting tyrosinase and downregulating MITF, and promotes epidermal proliferation and differentiation. Additionally, it modulates enzymes like elastase, hyaluronidase, and collagenase, which are implicated in skin aging.

Key findings
- 01 Topical application accelerated epidermal permeability barrier recovery in young mice after acute disruption, associated with increased proliferation, filaggrin expression, and lamellar body secretion.
- 02 Topical application in aged mice not only accelerated barrier recovery but also reduced skin surface pH, enhanced differentiation, and increased lipid production and lamellar body formation.
- 03 Topical application on a reconstructed human epidermis for 14 days demonstrated a reduction in pigmentation.
- 04 Topical hesperetin (aglycone of hesperidin) applied twice daily for 12 weeks increased stratum corneum hydration, skin elasticity, and hyaluronan accumulation in the dermis.

The Formula
Formulation
Stability
Hesperidin presents formulation challenges due to its inherent poor solubility in both water (approximately 1g in 50L) and oil, potentially limiting skin bioavailability. However, its derivative, Glucosyl Hesperidin, offers enhanced water solubility. Hesperidin itself can be solubilized in dilute alkali, pyridine, or hot water (>70°C). Aqueous solutions maintain stability for up to two months within a pH range of 1.0–7.4 at temperatures up to 40°C. Degradation may occur with exposure to light, air, elevated temperatures, or sonication during extraction processes. Direct use of orange peel extract, which contains hesperidin, can cause irritation due to its low pH, emphasizing the need for correct formulation and appropriate concentrations in products.
Safety
Safety Profile
Hesperidin is generally considered safe and well-tolerated for topical use, with scientific studies indicating a low incidence of allergic reactions or skin irritation. Individuals with known citrus allergies should exercise caution. Its use is permitted under the European Cosmetics Regulation, and a preliminary patch test is advised for sensitive skin types. The Norwegian Scientific Committee for Food and Environment (VKM) has concluded that hesperidin is safe for use in dietary supplements at doses of 2, 25, and 60 mg, though this refers to oral intake.
