Science
Mechanism of Action
This extract functions as a potent antioxidant, neutralizing free radicals to shield skin cells from oxidative stress and mitigate photoaging. Its anti-inflammatory capabilities reduce redness and irritation, fostering a calmer skin environment. Furthermore, it aids in the proliferation of new skin cells, improves moisture retention, and stimulates collagen production, crucial for maintaining skin firmness and elasticity. The extract also contributes to the reduction of age spots by potentially inhibiting melanogenesis and contains beneficial phytochemicals like flavonoids, iridoids, and coumarins.

Key findings
- 01 In a clinical study involving 49 women (aged 38-55) using a noni-based skincare regimen daily for six weeks, significant reductions in lateral canthal fine lines and wrinkles were observed. Improvements in skin elasticity and firmness, along with a decrease in the appearance of age spots and discolorations, were also noted, without evidence of irritation.
- 02 Animal studies (male Wistar rats) identified a 20% concentration of Morinda Citrifolia Leaf Extract as optimal for wound healing, demonstrating slight effects on fibroblasts, wound diameter, healing time, and inflammatory markers (TNF-α, IL-1) as well as growth factors (PDGF, TGF-β). Concentrations up to 30% showed no significant additional benefits.
- 03 Morinda Citrifolia leaf extracts have demonstrated the ability to mitigate UVB-induced erythema (skin reddening).

The Formula
Formulation
Stability
This extract exhibits good solubility in both water and ethanol. Its optimal pH range for formulation is between 3.9 and 7.2. For maximal durability, approximately 24 months, it should be stored in a cool, dry, tightly sealed container, protected from moisture, heat, and strong odors. A color shift may occur over time depending on storage temperature.
Safety
Safety Profile
Morinda Citrifolia Leaf Extract generally presents a favorable safety profile. Chronic toxicity studies in mice indicated no observable toxicity for leaf extracts, contrasting with fruit extracts which showed toxicity at high doses. Acute toxicity tests in rats with aqueous and ethanolic leaf extracts also found no toxicity. However, individuals with sensitivities to tropical fruits should exercise caution, and patch testing is advisable due to a potential, albeit low, risk of allergic reactions such as rashes or itching. Regulatory guidance specifically for cosmetic use is not stringent, emphasizing adherence to general safety and quality standards by manufacturers.
