Science
Mechanism of Action
This ingredient operates through several key pathways to optimize skin health. It functions as a potent antioxidant, actively neutralizing free radicals and mitigating oxidative stress from environmental aggressors. Its anti-inflammatory properties effectively calm and soothe irritated skin. Furthermore, studies indicate it promotes collagen synthesis, inhibits collagen degradation by reducing matrix metalloproteinase-1 (MMP-1) activity, and stimulates fibroblast proliferation, leading to enhanced skin elasticity and a reduction in wrinkle depth. It also demonstrates efficacy in preventing UVB-induced skin damage and erythema, modulating immune balance, restoring compromised skin barrier function, and exhibiting antimicrobial activity while stimulating cellular regeneration.

Key findings
- 01 A 4-week study utilizing an ethanol extract of noni leaves, specifically at a 7.5% concentration within a lotion, demonstrated significant anti-aging improvements. Participants experienced an increase in skin water content and a measurable reduction in pore size, blemishes, and wrinkles. While lower concentrations (2.5% and 5%) also conferred benefits, the 7.5% concentration proved to be more effective.
- 02 A 6-week clinical trial of a comprehensive skincare regimen featuring Morinda citrifolia significantly reduced lateral canthal fine lines and wrinkles, commonly known as 'crow's feet,' in women aged 38-55. This regimen also improved skin elasticity and firmness, with no reported instances of irritation.

Stability
Ethanol extracts of noni leaves in oil-in-water emulsions exhibited stability within a pH range of 6.3-6.8 for a duration of 4 weeks when stored at room temperature. For optimal general storage, the standardized extract powder should be maintained in a cool, dry environment (<28ºC), shielded from direct sunlight, with refrigeration being ideal. It boasts a shelf life of 24 months in its original sealed packaging under conditions below 25°C, relative humidity below 65%, and odor-free surroundings, ensuring no direct contact with walls or floors. It's important to note that while the active components are water-extractable, the raw powder may contain insoluble fibrous material.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically assessed Morinda Citrifolia Leaf Powder. However, a clinical trial of a Morinda citrifolia-based skincare regimen reported no instances of irritation. Morinda citrifolia leaves are generally considered safe for topical application. It is important to note that some individuals, particularly those with sensitivities to tropical fruits, may experience allergic reactions, such as skin rashes or itching, when exposed to Morinda Citrifolia fruit extract, a distinct but related material.
