Collagen is widely recognised for its role in maintaining youthful skin, and it is known for enhancing elasticity and minimising wrinkles[1]. As the most abundant protein in the body, it serves as a vital structural element for skin, joints, tendons, and connective tissues[2]. However, collagen production naturally declines with age, leading to visible signs of ageing, such as fine lines, sagging skin, and reduced skin hydration[3][4]. This has driven the popularity of collagen supplements in anti-ageing regimens, with both oral and topical formats being widely embraced.
In this blog, we delve into the science of collagen, explore how it impacts ageing, and examine what studies say about its effectiveness as an anti-ageing remedy.
Key Takeaways
- • Collagen is the body’s most abundant protein, responsible for skin elasticity, hydration, and firmness. Its natural decline with age contributes to visible signs of ageing, such as wrinkles and sagging.
- • Studies show that oral and topical collagen supplementation improves skin elasticity, hydration, and wrinkle reduction. Neither method is superior, but both offer anti-ageing benefits.
- • Long-term collagen supplementation yields more pronounced skin hydration and elasticity results than short-term use, emphasising the importance of consistency.
- • UV exposure, smoking, poor nutrition, and stress accelerate collagen depletion, highlighting the importance of supplementation to combat environmental damage.
Understanding Collagen: The Body’s Structural Protein
Collagen is a structural protein that acts as the “glue” in the human body, holding together skin, bones, muscles, and connective tissues[5]. It comprises amino acids such as glycine, proline, and hydroxyproline, forming a unique triple-helix structure that provides tensile strength and flexibility[5]. Among the 28 known types of collagen, Types I, II, and III are the most prevalent in the skin and joints, contributing to elasticity, hydration, and resilience[2].
Naturally produced by the body, collagen is crucial in maintaining skin integrity, joint mobility, and wound healing[2]. Fibroblasts become less active from early adulthood, leading to a decline in collagen production of approximately 1.0% to 1.5% per year[4]. Environmental factors like UV exposure, smoking, and poor nutrition further accelerate this decline, making collagen supplementation a popular choice to counteract the effects of ageing[6].
How Collagen Impacts Ageing
Ageing is accompanied by a natural reduction in collagen levels, leading to structural changes in the skin[3]. As collagen diminishes, the skin loses its elasticity, resulting in wrinkles and sagging[3][7]. This decline also impacts the dermis, the skin’s thickest layer, which becomes thinner and less hydrated over time[8][9].
Collagen helps combat these effects by:
- • Restoring Skin Elasticity: The skin regains firmness and suppleness by replenishing collagen levels[1].
- • Improving Hydration: Collagen retains moisture in the skin, reducing dryness and roughness[1].
- • Reducing Wrinkles: Enhanced collagen synthesis smooths out fine lines and wrinkles, giving the skin a youthful appearance[1].
- • Supporting the Skin Barrier: Collagen fortifies the dermis, improving the skin’s ability to resist environmental damage[10].
What Do Studies Say About Collagen and Anti-Ageing?
Collagen’s role in anti-ageing has been widely studied, with both oral and topical applications showing promise. Below, we summarise findings from credible research:
1. Oral Collagen Improves Skin Elasticity and Hydration
A review of existing literature, as noted in a study published on PubMed, concluded that oral collagen supplements can enhance skin elasticity, hydration, and turgor while reducing wrinkles and roughness[1]. However, the study highlighted a need for more large-scale trials to validate these findings across diverse populations.
2. Enhanced Radiance and Firmness with Collagen Beverages
A clinical study published in Science Direct examined the effects of a collagen tripeptide beverage on young and middle-aged women. Over eight weeks, participants experienced significant improvements in skin hydration, firmness, and radiance[11]. The study attributed these effects to the bioavailability of collagen peptides detected in participants’ blood samples, confirming absorption and efficacy[11].
3. Long-Term Collagen Use Shows Superior Results
Research from PubMed Central revealed that long-term collagen supplementation yields better results than short-term use[12]. Over several months, participants showed marked improvements in skin hydration and elasticity[12]. The findings emphasised the importance of consistency in collagen supplementation for anti-ageing benefits.
4. Oral and Topical Collagen Are Equally Effective
A comprehensive review on ResearchGate highlighted that oral and topical collagen effectively reduces signs of ageing[13]. The study observed improvements in skin moisture, elasticity, and wrinkle reduction, with no significant differences between the two formats[13]. This indicates collagen can be beneficial when consumed as a supplement or applied topically[13].
5. Role of Bioactive Ingredients in Collagen Production
Bioactive compounds, including peptides and amino acids, significantly promote collagen synthesis[14]. These substances enhance collagen production, strengthen the skin barrier and mitigate oxidative stress, a key factor in ageing[14]. Integrating bioactive peptides into collagen supplements can enhance their anti-ageing potential by promoting structural integrity and protecting against environmental aggressors[14][15][16].
6. Combating Photoageing with Collagen Supplements
Ultraviolet (UV) radiation accelerates collagen degradation, leading to skin photoaging, wrinkles, and reduced elasticity[14][17]. According to a study, oral supplementation with bioactive collagen peptides can help mitigate these effects by promoting collagen synthesis and reducing oxidative stress[14][18]. These peptides activate key signalling pathways, such as TGF-β/Smad, which play a critical role in skin repair and maintaining collagen structure[14][19].
While these studies are promising, researchers emphasise the need for more robust trials with larger sample sizes and diverse demographics. This will help solidify the role of collagen in anti-ageing and address questions regarding dosage, long-term effects, and efficacy across different populations.
Benefits of Collagen for Anti-Ageing
Collagen’s unique properties make it an indispensable part of anti-ageing routines. Here are the key benefits of collagen:
1. Improves Skin Elasticity and Hydration
Collagen enhances the skin’s ability to retain moisture, reducing dryness and restoring suppleness. Studies confirm its role in smoothing wrinkles and maintaining a youthful glow[11][14].
2. Reduces Fine Lines and Wrinkles
By replenishing the skin’s collagen matrix, supplements minimise the depth and appearance of wrinkles, particularly around the eyes and mouth[1].
3. Promotes Skin Firmness and Texture
Collagen strengthens the dermal layer, improving firmness and refining skin texture[1]. This helps restore the skin’s natural bounce and resilience.
4. Supports Joint Health
Although primarily known for its skincare benefits, collagen aids joint mobility by repairing cartilage and connective tissues[20].
5. Prevents Skin Ageing Caused by Environmental Stressors
Collagen supplements can help counteract damage caused by UV rays and pollution by fortifying the skin barrier[14].
6. No Known Adverse Effects
Existing studies have not identified any significant side effects from oral collagen supplementation, making it generally safe for most individuals[1]. However, some people may experience mild digestive discomfort, such as bloating or nausea[21]. To ensure collagen supplements are suitable for your individual needs, it is best to consult a healthcare expert before use.
Can Collagen Reverse Ageing?
No, collagen cannot entirely reverse ageing, but it helps reduce the visible signs of it. By replenishing the body’s declining collagen levels, it improves skin elasticity, hydration, and firmness, smoothing wrinkles and promoting a youthful appearance. While collagen works to slow the effects of ageing, consistent supplementation can support long-term skin health and enhance overall radiance.
Conclusion
Collagen is an integral part of the body’s structural framework, and its decline with age significantly impacts skin health and appearance. Research has shown that oral and topical collagen supplements can improve skin elasticity, hydration, and firmness while reducing wrinkles and roughness. Studies further highlight the importance of consistent, long-term use for achieving optimal results.
