Science
Mechanism of Action
This extract enhances skin health by stimulating the skin’s barrier function, thereby improving moisture retention and bolstering defense against environmental aggressors. It delivers essential minerals such as calcium, magnesium, and zinc, which contribute to overall skin comfort and assist in regulating the skin’s optimal pH balance. As an antioxidant, it actively neutralizes free radicals to combat oxidative stress, which can mitigate the appearance of wrinkles and uneven skin tone. The extract also targets hyperpigmentation by reducing melanin synthesis, specifically by antagonizing endothelin, leading to a more uniform skin tone. Additionally, it gently promotes exfoliation and accelerates cell turnover, fostering smoother, more luminous skin. Its amino acid and mineral content nourishes, supports cellular regeneration, repairs damaged cells, and enhances fibroblast migration, cell proliferation, and collagen formation and deposition.
Research
Clinical Evidence
Medium confidenceN/A
Key findings
- 01 In vitro studies demonstrated that concentrations of 5 μg/mL, 25 μg/mL, and 50 μg/mL effectively promoted the proliferation and migration of L929 and MEF fibroblasts.
- 02 Soluble Pearl Extract (SPE) at concentrations of 0.1 μg/mL and 1 μg/mL abolished the endothelin-1 induced effects on melanin synthesis, tyrosinase activity, TYR, and TRP-1 mRNA expression in B16 melanoma cells, indicating significant skin lightening properties.
- 03 An 8-week clinical trial utilizing 3 g/d of pearl powder showed an increase in total antioxidant capacity, total thiols, and glutathione content, alongside a suppression of lipid peroxides products.
Transparency
Dusting Analysis
While in-vitro studies indicate efficacy at specific microgram per milliliter concentrations, there is a lack of established optimal topical percentages from human clinical trials for PEARL SAC SECRETION EXTRACT. Products incorporating this ingredient without clear concentration information or robust efficacy data may be susceptible to 'dusting' claims, offering perceived benefits without delivering true active concentrations.
