Science
Mechanism of Action
Hydrolyzed Pearl functions through a synergistic action of its core components: amino acids, minerals (calcium, magnesium, zinc), and conchiolin protein. The amino acids facilitate crucial skin protein synthesis, while conchiolin, acting similarly to keratin, is absorbed by skin cells to support collagen transformation and production, vital for maintaining skin suppleness and elasticity. It forms a hydrating barrier on the skin's surface, effectively preventing moisture loss. Furthermore, it inhibits tyrosinase activity, the enzyme responsible for melanin synthesis, leading to a brighter, more even skin tone. By promoting Superoxide Dismutase (SOD) activity and reducing reactive oxygen species (ROS), it offers robust antioxidant protection against oxidative stress and photoaging, simultaneously controlling the degradation of collagen I and reducing MMP-1 protein expression. Its capacity to promote proliferation and migration of human microvascular endothelial cells also supports efficient wound healing and overall skin regeneration.

Key findings
- 01 Regular application of Hydrolyzed Pearl in leave-on formulations at concentrations of 0.5-3% led to measurable improvements in skin firmness and a reduction in visible signs of aging within 8-12 weeks.
- 02 Hydrolyzed Pearl effectively inhibited UVA-induced photoaging of human skin fibroblast cells at 200 mg/L, demonstrated by improved antioxidant activity, inhibition of apoptosis, and controlled degradation of collagen I protein.
- 03 Pearl powder components, at 25 μg/mL, showed significant promotion of migration and higher proliferation for L929 and MEF cells, indicating strong potential for wound healing.
- 04 Micro and nano-sized pearl powders (5 μg/mL and 20 μg/mL) enhanced skin cell distribution and passage, accelerated wound closure, and significantly improved the biomechanical strength of recovered tissue in a rat skin excision model, with nano-sized particles exhibiting superior healing efficacy.
- 05 Up to 5% concentration is effective in wash-off formulations, maintaining product stability and cost-effectiveness while delivering benefits.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) and SCCS have not conducted specific safety assessments for Hydrolyzed Pearl. While the FDA does not pre-approve cosmetic ingredients, an advisory related to 'pearl powder' concerned an unauthorized product's notification status, not the ingredient's general safety. Adverse reactions are reported to be relatively uncommon; however, patch testing is recommended prior to extensive use to assess individual skin compatibility.
