SHARK FIN EXTRACT.

Valuable / HUMECTANT, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Shark Fin Extract is a marine-derived collagen source, primarily composed of elastoidin, a protein known for its structural role. When applied topically, it functions as a potent humectant and emollient, significantly enhancing skin's moisture retention and barrier integrity.

Summary

Humectant Emollient Skin Conditioning Film-forming Barrier Support Moisturizer

Science

Mechanism of Action

This extract operates by leveraging its collagenous protein fibers, notably elastoidin, which mimics Type III collagen, to form a hydrating film on the skin. It effectively binds water, acting as a humectant to draw and retain moisture within the stratum corneum, while also providing emollient properties to soften and smooth the skin's surface. This dual action helps to suppress transepidermal water loss (TEWL) and reinforce the skin's natural barrier function.

Key findings

  1. 01 Shark Fin Atelocollagen (AFN-221/AFM-521) significantly improved skin moisturization, suppressed transepidermal water loss, enhanced skin barrier function, and aided in chapping recovery. This form of collagen demonstrated 10 to 16 times higher moisturizing effects compared to hydrolyzed collagen.
  2. 02 Topical application of a gel containing lyophilized hydrolyzed blue shark cartilage (Prionace glauca), a related collagen-rich source, improved skin moisture, texture, and complexion, while also helping to control oil and smooth wrinkles on human inner wrist skin over 10 and 20 minutes.

Stability

One specific form, Shark Fin Atelocollagen (MS), demonstrated good emulsion stability and compatibility. It remained stable for at least one month at room temperature when mixed at a 0.2% concentration with common cosmetic raw materials like sodium hyaluronate, glycerin, xanthan gum, and various glycols.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Shark Fin Extract or its specific collagen components (e.g., Atelocollagen) have not been formally reviewed by CIR or SCCS. While the FDA has cautioned against unauthorized products containing 'Shark Oil (Squalene)', this refers to a distinct ingredient. Concerns regarding mercury levels typically apply to the consumption of shark fins, not purified topical extracts. Notably, Shark Fin Atelocollagen has yielded a 'Negative' result in Human Repeat Insult Patch Testing (HRIPT), indicating a low potential for skin irritation or sensitization under tested conditions.
