HYDROLYZED PEARL

Last update on Feb 13, 2026

Hydrolyzed Pearl is a water-soluble protein hydrolysate obtained from natural pearls (typically from freshwater or saltwater sources such as Pinctada martensii). Through controlled hydrolysis (acid, enzymatic, or other methods), large pearl proteins (conchiolin and others) are broken down into smaller peptides and amino acids. Rich in calcium, amino acids, trace minerals, and bioactive compounds, it provides moisturizing, conditioning, brightening, and protective benefits. This ingredient is popular in premium anti-aging serums, moisturizers, eye creams, masks, and brightening treatments, where it supports hydration, radiance, smoothness, and a refined complexion.

What is HYDROLYZED PEARL used for?

  • Skin conditioning: Maintains skin in good condition and improves softness, hydration, and suppleness. Frequently used in moisturizers, serums, creams, and masks for nourished, refined skin.
  • Moisturizing / Film forming: Forms a light protective film to retain moisture and smooth the skin surface. Ideal for dry, dehydrated, or mature skin products targeting barrier support and comfort.
  • Brightening & radiance: Enhances skin glow and helps reduce dullness. Common in brightening serums, eye contour treatments, and luxury skincare for a luminous, even-toned appearance.

Origin

Hydrolyzed Pearl is sourced from natural pearls harvested from oysters or mussels. Pearls are cleaned, crushed or powdered, then subjected to controlled hydrolysis (acid, enzymatic, or other methods) to break down insoluble proteins into soluble peptides. The resulting hydrolysate is purified and concentrated into a liquid or powder form. This gentle process preserves bioactive components like amino acids and minerals, making it suitable for premium and natural cosmetic formulations.

Safety Profile

Hydrolyzed Pearl is considered safe for cosmetic use, with a low hazard rating from EWG (typically 1) and minimal concerns for irritation, sensitization, or toxicity at typical concentrations (0.1-5%). It is well-tolerated across skin types, including sensitive, and poses low risk of comedogenicity or allergic reactions. As a marine-derived ingredient, rare sensitivities may occur in those allergic to shellfish or pearls. Patch testing is recommended.
