Marine Collagen and Sun Damage: Does It Help Protect Against UV Rays? - Genetic Nutrition

Marine Collagen and Sun Damage: Does It Help Protect Against UV Rays?

, by Sandesh Prasannakumar, 10 min reading time

As people become more informed of the danger impact of ultra violet (UV) rays, the need for skin protection mechanisms has grown. From numerous approaches, marine collagen proved to be an effective skin care ingredient. Commonly used to enhance skin elasticity and moisture, marine collagen has recently been considered as a potent UV shield for the skin. This article focuses on the details of marine collagen and analyzes its effectiveness for UV protection.

Understanding UV Radiation and Its Effects on Skin

1. Types of UV Radiation

UV radiation from the sun is categorized into three types: UVA, UVB, and UVC.

  • UVA: These long-wave rays penetrate deep into the skin. It can cause aging and long-term damage.
  • UVB: These short-wave rays affect the outer layer of your skin. It can lead to sunburn and contribute to skin cancer.
  • UVC: This is the shortest and most dangerous type of ray. However, these are generally absorbed by the Earth's atmosphere and don't reach the ground.
2. Impact of UV Radiation

Exposure to UV radiation can have several adverse effects on the skin:

  • Photoaging: Premature aging of the skin. Some characteristics of this situation include wrinkles, fine lines, and loss of elasticity.
  • Sunburn: Acute skin damage. You may experience redness, inflammation, and pain.
  • DNA Damage: UV radiation can cause DNA mutations. This can lead to skin cancer.
  • Pigmentation: Increased melanin production. This can cause dark spots and uneven skin tone. 

Marine Collagen: An Overview

1. What Is Marine Collagen?

Marine collagen is sourced from the skin, scales and bones of fish. It is a type of collagen protein, being composed mostly of Type I and Type III collagen, without which skin cannot perform correctly. Marine collagen is considered as a highly bioavailable form of collagen, which is easily absorbed in the body and mainly used for skin, hair, nails, and joint health.

2. Benefits of Marine Collagen

Skin Health: Enhances skin elasticity, hydration, and firmness.

Hair and Nails: Strengthens hair and nails, reducing brittleness.

Joint Support: Aids in maintaining joint flexibility and reducing inflammation.

3. How Marine Collagen Works

Marine collagen acts through supplying the body with basic amino acids such as glycine, proline, and hydroxyproline. They are all essential for the synthesis of collagen and other proteins involved in skin maintenance and repair.

Collagen and UV Protection: The Connection

1. Collagen's Role in Skin Structure

Collagen is the fibrous protein accounting for 70% of the dry weight of the skin tissue. It gives strength and flexibility to the skin besides offering resistance to skin stretching mechanisms. As people grow older and spend more time under the sun, their capacity to produce new collagen reduces and the skin loses its strength and elasticity.

2. Marine Collagen's Potential in UV Protection

The results obtained in the most recent experiments indicate that marine collagen could also provide some shielding against the effects of UV radiation. The potential mechanisms include:

  • Collagen Synthesis: Marine collagen enhances the levels of production of collagen, thus the skin stays well structured to prevent frequent damage by the UV rays.
  • Antioxidant Properties: Collagen peptides found in marine products act as antioxidants and help to counter the free radicals which result from UV exposure.
  • Repair and Regeneration: Marine collagen is responsible for the repair of damaged skin cells and stimulates the healing of the skin tissue.
3. Scientific Evidence

Several studies have explored the role of collagen in skin health and its potential protective effects against UV radiation.

A Study on Collagen Supplementation: According to an article in Journal of Cosmetic Dermatology, the outcome of a trial of oral collagen supplements was that they enhanced skin moisture, elasticity, and skin texture. Such enhancement of skin health helps to increase the level of resistance to UV damage.

Antioxidant Effects: It was established through a study published in the Journal of Drugs in Dermatology that collagen peptides could possess antioxidants, which can help shield skin cells from damage caused by free radicals from UV exposure.

Practical Applications of Marine Collagen for UV Protection

1. Supplementation

Using marine collagen supplements can be a good strategy, which adds convenience in maintaining good skin. It is also recommended to find good brand marine collagen supplements and it is preferred if the collagen supplement contains hydrolyzed collagen for better absorption.

Recommended Dosage: The intake can vary from 5 to 10 grams per day, but it is more beneficial to adhere to the instructions of the manufacturer or a doctor.

2. Topical Products

You can also use marine collagen in topical formulations. For example, creams, serums, and masks. They can target your skin and promote its health. 

Application: Use as directed, typically once or twice daily, as part of your skincare routine.

3. Combining with Sunscreen

Remember not to replace sunscreen with marine collagen. Instead, use it as a complementary approach along with broad-spectrum sunscreen to provide comprehensive protection against UV radiation.

Sunscreen Use: Apply a broad-spectrum sunscreen with at least SPF 30 daily, reapplying every two hours when exposed to sunlight.

Comprehensive Skin Protection Strategy

1. Sunscreen

The most effective way to protect against UV damage is by using sunscreen. Choose a broad-spectrum sunscreen that protects against both UVA and UVB rays.

Tips:

  • Apply Generously: Use enough sunscreen to cover all exposed skin.
  • Reapply: Reapply every two hours, or more often if swimming or sweating.
  • Year-Round Use: Use sunscreen year-round, even on cloudy days, as UV rays can penetrate through clouds.
2. Antioxidants

Incorporate antioxidants into your skincare routine and diet to combat oxidative stress from UV exposure. Vitamins C and E are particularly beneficial.

Sources:

  • Topical: Antioxidant serums and creams.
  • Diet: Fruits, vegetables, nuts, and seeds rich in antioxidants.
3. Hydration

Maintaining skin hydration is crucial for its health and resilience. Hydrated skin is less likely to suffer from dryness and damage due to UV exposure.

Tips:

  • Hydrate Internally: Drink plenty of water throughout the day.
  • Moisturize Externally: Use hydrating skincare products, especially those containing hyaluronic acid.
4. Avoid Peak Sun Hours

Limit exposure to direct sunlight during peak hours (10 a.m. to 4 p.m.) when UV radiation is strongest. Seek shade or wear protective clothing during these times.

Protective Clothing:

  • Hats: Wide-brimmed hats to protect the face and neck.
  • Clothing: Long-sleeved shirts and pants made from tightly woven fabrics.

Conclusion

Marine collagen shows promise as a supportive measure in protecting the skin from UV damage. By enhancing collagen synthesis, providing antioxidant benefits, and aiding in the repair and regeneration of skin cells, marine collagen can contribute to a comprehensive skin protection strategy. However, it should not be relied upon solely for UV protection. The best approach combines marine collagen supplementation with proven methods like using broad-spectrum sunscreen, maintaining a healthy diet rich in antioxidants, and adopting sun-safe behaviors.

Incorporate marine collagen as part of a holistic skincare routine to support overall skin health and resilience against the harmful effects of UV radiation. Embrace a balanced approach to skincare, combining nutrition, topical care, and sun protection to maintain healthy, youthful skin.
