If you’re passionate about skincare, you certainly must have come across the term “collagen” several times. It is one of the key natural ingredients found in countless beauty products, renowned for its numerous benefits for the skin. Despite its widespread use, understanding collagen is still a daunting task. But, we have made it easy for you with this simple guide, where we’ll explore the essentials of collagen, its role in maintaining a youthful complexion, and learn why it’s such a key ingredient in the skincare world.
What is Collagen?
Collagen is a rich source of natural protein in your body, making up around 30% of the total protein content. It is found in your skin, bones, muscles, tendons and ligaments. Essentially, collagen is what keeps your skin looking smooth, firm and youthful.
There are over 28 types of collagen identified, but when it comes to skin health, a few stand out as particularly important. Type I collagen is the most abundant, making up about 90% of your body’s total collagen. It is crucial for providing structure to your skin, bones, tendons and ligaments, playing a major role in keeping your skin firm and resilient.
Type III collagen is also vital, often working alongside Type I to enhance skin elasticity, and is also found in muscles, arteries and organs. Type IV collagen is found in the layers of your skin and helps support the skin’s overall structure. While Type II collagen is more specific to joint health and Type V collagen is important for your eyes, hair, and certain skin layers, Type I and III are particularly essential for maintaining youthful, elastic skin.
The Role of Collagen in Skin Health
Collagen plays a crucial role in maintaining your skin’s youthful appearance. Here’s how:
Skin Elasticity and Firmness
Collagen fibres are essential for keeping your skin tight and firm. As you age, your body produces less collagen, which leads to the skin losing its elasticity. Which is why wrinkles, sagging, and fine lines start to appear.
Hydration and Moisture Retention
Collagen also helps your skin retain moisture. It works with hyaluronic acid to keep your skin plump and hydrated. When collagen levels decline, your skin may appear dull, dry, and most likely to break out.
Wound Healing
Collagen is crucial for wound healing. When your skin is injured, collagen production repairs and regenerates the damaged tissue. Due to this process, scars often fade over time as new collagen forms and rejuvenates the skin.
Protection Against Environmental Damage
Collagen also helps create a barrier that protects your skin from harmful damage by UV rays, pollution, and toxins. It acts as a shield, preventing these harmful elements from penetrating deeper layers of the skin.

The Ageing Process and Collagen Loss
Unfortunately, collagen production naturally declines as you age. Starting in your mid-20s, your body begins to produce about 1% less collagen each year. By the time you reach your 40s and 50s, this reduction becomes more noticeable, and the signs of ageing, wrinkles, sagging skin, and fine lines, become more prominent.
Causes of collagen loss
Sun Exposure
UV radiation is one of the biggest reasons behind collagen breakdown. It damages the collagen fibres in your skin, leading to premature ageing, often referred to as photoaging.
Smoking
The chemicals in cigarettes can damage collagen and elastin, causing loss of skin elasticity and the formation of wrinkles, particularly around the mouth.
Poor Diet
Your food intake is as important as your skincare regime. A diet high in sugar and refined carbohydrates can increase the production of advanced glycation end products (AGEs), which damage collagen fibres and make them more prone to breaking.
Stress
Stress affects your overall health, including skin health. Chronic stress can increase cortisol levels, which has been linked to the breakdown of collagen.
How to Boost Collagen Production
While collagen loss is a natural part of ageing, there are steps you can take to slow down the process and even boost collagen production:
Healthy Diet
A diet rich in protein, vitamins, and minerals is essential for collagen production. Foods like bone broth, chicken, fish, egg whites, citrus fruits, berries, and leafy greens can boost collagen production.
Collagen Supplements
Collagen supplements, usually in the form of powders or capsules, have gained popularity for their potential to improve skin elasticity and hydration. These supplements typically contain hydrolysed collagen, which is broken down into smaller, more easily absorbed molecules.
Skincare
Skincare products containing ingredients like retinoids, vitamin C, and peptides can help increase collagen production. Retinoids increase collagen synthesis, while vitamin C is crucial for collagen formation and stability.
Sun Protection
Protecting your skin from UV damage is crucial for preserving collagen. Daily use of sunscreen with at least SPF 30 can help prevent collagen breakdown caused by sun exposure.
Healthy Lifestyle Choices
Avoiding smoking, managing stress, and getting enough sleep are all important for maintaining healthy collagen levels. Regular exercise can also help improve circulation, which in turn supports collagen production.
Adding to this, Dr Vichitra Sharma, Consultant and Dermatology at Amrita Hospital Faridabad suggested, "Consider treatments like skin boosters, platelet-rich plasma (PRP), growth factor concentrate (GFC) treatments, micro needling, micro needling radiofrequency (MNRF), and other lasers like Nd Yag to boost collagen levels. Your dermatologists will examine and prescribe the most suitable procedures. Recently, the popular ones are polynucleotide (PN) and poly deoxyribonucleotides (PDRN) and exosome treatment options."
Conclusion
Collagen is the key player for youthful and healthy skin. It provides structure, strength, and elasticity, keeping your skin looking firm and radiant. While the natural decline in collagen production is an inevitable part of ageing, a healthy diet, sun protection, and the right skincare products can all contribute to maintaining a youthful appearance. By understanding the essential role collagen plays in skin health, you can make the right choices to keep your skin looking its best for years to come.
