Science

Mechanism of Action

Rubus Idaeus Juice exerts its beneficial effects through a synergy of active compounds, including antioxidant polyphenols (like anthocyanins and ellagitannins), brightening Vitamin C, and exfoliating organic acids (citric and malic acid). These components collectively neutralize free radicals and mitigate UVB-induced oxidative stress, while also contributing to a more even skin tone and gentle enzymatic exfoliation. Additionally, its anti-inflammatory properties soothe irritation, and components like fatty acids support barrier function and hydration, with some extracts proven to induce critical hydration-related genes and stimulate ceramide production.

Key findings

  1. 01 Red raspberry extracts demonstrated significant antioxidant activity, with DPPH scavenging IC50 values as low as 1.6 µg/mL for aeroponic varieties, and effectively inhibited lipid peroxidation by 42.6% at 100 µg/mL.
  2. 02 In hairless mice and keratinocyte models, red raspberry extract (RBE) provided protection against UVB-induced photodamage, reducing signs of photoaging such as skin thickening, erythema, wrinkles, and dryness. This protective action involved activating Nrf2 signaling and suppressing the NF-κB inflammatory pathway.
  3. 03 An oil-soluble extract derived from Rubus idaeus cells was shown to upregulate genes crucial for skin hydration (including aquaporin 3, filaggrin, involucrin, and hyaluronic acid synthase). It also stimulated glucocerebrosidase activity, which is vital for ceramide synthesis, leading to enhanced skin-hydrating capacity both in vitro and in vivo.

Sensitization risk Moderate

Rubus Idaeus Juice is generally well-tolerated across most skin types. However, individuals with known allergies to berries or raspberries should perform a patch test. While typically non-irritating, the natural tannin content may potentially cause irritation for highly sensitive skin. The 10% maximum concentration refers to a recommended incorporation rate for fruit extract by suppliers, not a strict regulatory safety limit. EWG Skin Deep rates Rubus Idaeus (Raspberry) Juice with low concerns for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity.
