Pep-Marine Placenta™ (Salmon Ovary Peptide)

peptides hydrolyzed from salmon ovary, found to have tremendous benefits to skin

1. Topical Benefits

a. Enhanced Skin Hydration and Barrier Function

• What it means: SOP may help improve the skin’s moisture content, leading to a smoother, more supple complexion.

• Possible mechanism: Some research suggests salmon-derived peptides can reinforce the skin’s natural barrier by boosting ceramide or lipid production and reducing transepidermal water loss (TEWL).

b. Increased Collagen Production and Skin Elasticity

• What it means: Topical SOP may support collagen synthesis in the dermis, which can enhance skin elasticity and reduce the appearance of wrinkles.

• Possible mechanism: Certain peptides from fish (including salmon) can stimulate fibroblasts—the cells responsible for producing collagen and other structural proteins in the skin.

c. Antioxidant and Anti-Inflammatory Properties

• What it means: SOP might have the capacity to neutralize free radicals and reduce inflammation in the skin. This could help protect against environmental stressors (e.g., UV-induced damage) and support a calmer complexion.

• Possible mechanism: Bioactive peptides in salmon roe or ovary extract may help downregulate pro-inflammatory mediators (like interleukins) and upregulate the body’s own antioxidant defenses (such as superoxide dismutase).

d. Wound-Healing Support

• What it means: Some data indicate that marine peptides can promote re-epithelialization (regrowth of the skin surface) and stimulate growth factor production.

• Possible mechanism: By enhancing fibroblast proliferation and migration, salmon-derived peptides might accelerate the repair of superficial skin injuries.
