The skin is made up of over 70% collagen, and the majority of that is Type I. As we age, our natural collagen production begins to decline—dropping by 1% each year after age 25. This decline leads to common signs of ageing like fine lines, wrinkles, sagging, dryness, and a dull complexion.
Here’s why marine collagen is particularly potent for reversing and preventing these effects:
Reduces Wrinkles and Fine Lines
Clinical studies have shown that consistent intake of marine collagen can visibly reduce the appearance of wrinkles. By replenishing lost collagen, the skin becomes plumper, firmer, and more elastic. Marine collagen stimulates fibroblast cells in the dermis to produce more collagen and elastin, helping to smooth out fine lines naturally.
Boosts Skin Hydration and Elasticity
Hydrated skin is youthful skin. Marine collagen enhances the skin’s moisture retention by supporting the extracellular matrix—the framework that holds water and nutrients. This is especially beneficial for people with dry or mature skin. Improvements in skin elasticity have also been observed in studies where participants consumed marine collagen for 8–12 weeks.
Enhances Skin Glow and Texture
Healthy collagen levels support skin cell turnover, giving you that coveted radiant glow. Users of marine collagen often report improvements in tone and texture, leading to smoother, softer, and more luminous skin. It also helps reduce roughness, patchiness, and dullness.
Promotes Skin Healing and Regeneration
Marine collagen has regenerative properties that can help heal wounds and reduce the appearance of scars and blemishes. It accelerates the production of new skin cells and helps maintain the structural integrity of the skin’s surface, promoting a smoother and more even complexion over time.
Helps Reduce Acne and Inflammation
Marine collagen contains amino acids like glycine, proline, and hydroxyproline, which have anti-inflammatory effects. By calming inflamed skin and supporting barrier function, marine collagen may indirectly reduce breakouts and improve acne-prone skin.
Other Skin Benefits of Type I Marine Collagen
- Protects against UV damage: Marine collagen can help protect skin from oxidative stress caused by sun exposure.
- Minimises under-eye puffiness: Collagen peptides can thicken and strengthen the skin under the eyes, reducing dark circles and puffiness.
- Improves skin firmness: It enhances skin density and elasticity, making your skin feel tighter and more toned.
Full-Body Benefits of Type I Marine Collagen
While the skin-enhancing perks often take center stage, marine collagen is a whole-body wellness ally. Here are more reasons to include it in your routine:
Supports Hair and Nail Growth
Marine collagen boosts the production of keratin—the protein responsible for strong, shiny hair and nails. Many users report faster-growing, thicker hair and stronger nails with fewer breaks and splits after regular supplementation.
Promotes Joint and Bone Health
Type I collagen is a structural protein in bones and joints. Marine collagen may help reduce joint pain, improve mobility, and even increase bone density by replenishing lost collagen in connective tissues. It’s especially useful for active individuals or those dealing with age-related joint stiffness.
Improves Gut Health
Marine collagen contains glycine and glutamine, amino acids that play a crucial role in gut lining repair. This makes it supportive for people with leaky gut, IBS, or digestive inflammation. A healthier gut also contributes to clearer, more vibrant skin.
Strengthens Cardiovascular System
Collagen supports the integrity of blood vessels and arteries. A deficiency can weaken arterial walls, contributing to cardiovascular problems. Marine collagen helps keep your heart and circulatory system strong by reinforcing vascular tissues.
Aids in Muscle Repair and Recovery
Though not a complete protein, marine collagen still supports muscle tissue repair and may help improve recovery after workouts. It complements resistance training by improving connective tissue strength and reducing injury risk.
Why Marine Collagen Is Better Than Other Types:
Superior Absorption: Marine collagen peptides are smaller than bovine or porcine peptides, making them more bioavailable—up to 1.5 times more absorbable.
Cleaner and More Sustainable: Marine collagen is often sourced from wild-caught fish and utilises parts that would otherwise go to waste, making it more environmentally friendly.
Low Allergen Risk: It’s free of common allergens like dairy and gluten and is a good alternative for people who don’t consume beef or pork products.
