HYDROLYZED FISH SCALE EXTRACT.

Valuable / HUMECTANT

Hydrolyzed Fish Scale Extract is a bio-active humectant and skin-conditioning agent, characterized by its low molecular weight peptides and amino acids. It precisely targets skin hydration and supports intrinsic collagen synthesis, leading to measurable improvements in moisture retention, skin texture, and the visible reduction of fine lines and pores.

Humectant Skin-Conditioning Agent Emollient

Science

Mechanism of Action

This extract functions primarily as a potent humectant and an effective skin-conditioning agent, adept at binding and retaining vital water within the stratum corneum. Composed of low molecular weight amino acids such as glycine, proline, and hydroxyproline, along with beneficial peptides, it is hypothesized to stimulate dermal fibroblast activity. This stimulation, in turn, may enhance the natural synthesis of endogenous collagen, contributing to improved skin elasticity and structural integrity.

Key findings

  1. 01 A clinical investigation utilizing a serum formulation, balanced at a pH of 7.7 and incorporating Hydrolyzed Fish Collagen, demonstrated significant enhancements across multiple skin parameters. Subjects reported notable increases in facial skin moisture, a measurable reduction in the appearance of pores and wrinkles, and amelioration of UV-induced acne after a consistent application period of at least 2 weeks.

Stability

This ingredient exhibits optimal stability within formulations across a pH range of 6.15 to 7.7. Specifically, preparations are well-suited for direct skin application at pH values between 6.15-6.58. Related gelatin hydrolysates demonstrate robustness across a broader pH spectrum, from 4 to 8. For cosmetic applications, advanced pretreatment and spray-drying processes are essential to effectively mitigate and eliminate any inherent fishy odor.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel thoroughly assessed Hydrolyzed Collagen, including fish scale-derived variants, concluding its safety for use in cosmetics in 1985, a finding reaffirmed in 2006. A 20% aqueous solution of fish scale-sourced Hydrolyzed Collagen (average molecular weight ~400 Da) proved non-sensitizing in a Human Repeat Insult Patch Test involving 50 subjects. Marine-derived collagen is inherently free from concerns regarding prions or terrestrial animal viruses. Furthermore, an oral LD50 estimated at greater than 2500 mg/kg body weight in rats for a 30% aqueous solution indicated no observable systemic toxicity or mortality.
