The Benefits of Collagen Supplements for Aging Skin: A Comprehensive Review

The Benefits of Collagen Supplements for Aging Skin: A Comprehensive Review

Ageing is an inevitable process that brings with it various changes in the body, most notably the skin. Over time, our skin loses its youthful elasticity and firmness, leading to wrinkles, sagging, and a generally tired appearance. Among the numerous interventions available to combat these signs of ageing, collagen supplements have gained significant attention. This article explores the benefits of taking collagen supplements for aging skin, supported by scientific evidence and expert insights.

Understanding Collagen and Its Role in Skin Health

Collagen is the most abundant protein in the human body, making up approximately 75% of the skin’s dry weight. It provides structure, strength, and elasticity to the skin. As we age, the production of collagen decreases, and the existing collagen fibres become fragmented and less organised. This degradation is a major contributor to the visible signs of ageing such as wrinkles, fine lines, and loss of skin firmness.

The Mechanism of Collagen Supplements

Collagen supplements typically come in the form of hydrolyzed collagen, which is collagen broken down into smaller peptides that are easier for the body to absorb. When ingested, these peptides are absorbed through the gastrointestinal tract and enter the bloodstream, where they can stimulate the body’s own collagen production and support skin repair and regeneration.

Clinical Evidence Supporting Collagen Supplementation

Several clinical studies have demonstrated the benefits of collagen supplementation for aging skin:

  1. Improvement in Skin Elasticity and Hydration: A 2014 study published in Skin Pharmacology and Physiologyfound that women who took a collagen supplement experienced a significant improvement in skin elasticity compared to those who took a placebo. Additionally, another study in Journal of Cosmetic Dermatology in 2018 reported enhanced skin hydration and dermal collagen density after collagen supplementation.

  2. Reduction in Wrinkles and Fine Lines: Research published in Nutrients in 2015 showed that oral collagen peptide supplementation reduced wrinkles and increased skin density and hydration. Participants noted a visible reduction in wrinkle depth and skin roughness after eight weeks of daily collagen intake.

  3. Support for Overall Skin Health: Collagen supplements have also been shown to improve overall skin texture and strength. A 2019 review in the Journal of Drugs in Dermatology highlighted that collagen peptides can improve skin barrier function, enhance wound healing, and provide protection against UV-induced skin damage.

Additional Benefits of Collagen Supplementation

Beyond the primary benefits for aging skin, collagen supplements may offer several other health advantages:

  • Joint Health: Collagen is a crucial component of cartilage, and supplementation can help reduce joint pain and improve joint function, which is particularly beneficial for individuals with osteoarthritis.
  • Bone Health: Collagen contributes to bone strength and density, potentially reducing the risk of osteoporosis.
  • Gut Health: Collagen supports the gut lining, aiding in digestion and potentially reducing symptoms of leaky gut syndrome.

Choosing the Right Collagen Supplement

When selecting a collagen supplement, it is important to consider the source and quality of the collagen. Marine collagen and bovine collagen are popular choices, each offering unique benefits. Marine collagen is known for its high absorption rate, while bovine collagen, such as the one used in By Beth products, is rich in type I and III collagen, which are vital for skin health.


The benefits of taking collagen supplements for aging skin are well-supported by scientific research. From improving skin elasticity and hydration to reducing wrinkles and enhancing overall skin health, collagen supplements offer a promising solution for those seeking to maintain a youthful appearance. By incorporating high-quality collagen supplements into your daily routine, you can support your skin’s natural structure and combat the signs of aging effectively.
