Science
Mechanism of Action
Sea urchin extract employs a multifaceted approach to enhance skin health. Its powerful peptides act as robust antioxidants, actively neutralizing free radicals generated by UV exposure and blue light, thereby protecting against oxidative damage and premature aging. The extract significantly promotes wound healing and tissue regeneration by enhancing the migration and proliferation of keratinocytes. Furthermore, it strengthens the skin barrier through ceramide synthesis, reduces hyperpigmentation by modulating tyrosinase activity, and delivers essential micronutrients like zinc, selenium, and omega-3 fatty acids for overall luminosity. Select peptides also activate key cellular longevity genes, SIRT1 and SIRT3, supporting quicker recovery from skin damage, while also demonstrating anti-inflammatory and antimicrobial properties.

Key findings
- 01 Clinical studies confirm that sea urchin peptide extracts, within a 1-5% concentration range, are effective in delivering antioxidant, brightening, and wound-healing benefits.
- 02 Consistent application of sea urchin peptides at concentrations between 0.5-2% has shown measurable improvements in skin.
- 03 A 3% cream formulation of *Echinometra matthaei* extract demonstrated superior wound healing properties in rat models.
- 04 In vitro research on unspecified peptide fractions revealed up to a 37% reduction in melanin synthesis, indicating significant brightening potential for hyperpigmentation.
- 05 Unspecified peptide hydrolysates exhibited potent antioxidant activity, with 92% DPPH radical scavenging comparable to pure ascorbic acid.

Stability
The peptide components of sea urchin extract are generally stable. However, their efficacy can be diminished by immediate co-application with high-pH cleansers or strong exfoliants, such as undiluted glycolic acid. Optimal performance for peptides is observed in slightly acidic to neutral pH environments.
Conflicts
- High-pH cleansers
- Strong exfoliants (e.g., undiluted glycolic acid)
Safety
Safety Profile
Clinical evaluations indicate sea urchin peptides are non-toxic and non-irritating, supporting their safety for daily topical use. Acute and subchronic toxicity studies further corroborate a favorable safety profile. Specifically, a 0.5% concentration of polyhydroxynaphthoquinone (PHNQ) pigments from sea urchins exhibited no dermal irritation in mouse skin tests.
