Collagen is a common topic in Korean skincare discussions and ingredient lists, but what exactly is it? In this blog, we explain what collagen is, why it is important and how you can support it.
What is collagen?
Collagen is a structural protein naturally found in your skin that contributes to its firmness, elasticity and structure. It forms a supportive network that helps keep the skin smooth and resilient. Discover our complete collagen cream range.
Why is collagen important?
As you get older, your natural collagen production gradually decreases. As a result, the skin can become less firm and elastic, and fine lines may become more visible. Skincare with collagen can mainly help hydrate the skin and make it appear smoother and plumper. Ingredients such as peptides can also support the skin, which is why they are popular in skincare focused on signs of ageing.
What affects collagen production?
As mentioned earlier, collagen production naturally decreases as you age. There are also other factors that can influence it:
- SPF protection: it is important to use a good SPF every day, as excessive sun exposure can accelerate collagen breakdown.
- Sleep: getting enough sleep is important for the natural recovery processes of your body and skin.
- High stress levels: prolonged or extreme stress can interfere with the skin’s natural renewal processes.
What are the benefits of collagen?
- Supports the skin’s normal structure, elasticity and overall appearance.
- Collagen is an important component of cartilage and contributes to its structure.
- Can help the skin look smoother and firmer and make fine lines appear less visible.
- Helps support and maintain a healthy skin barrier.
Can you apply or consume collagen?
If you are wondering whether collagen can only be consumed or whether it can also be applied to the skin: both options exist, but they work in different ways. Topical collagen skincare mainly helps hydrate the skin and make it appear smoother and plumper, while supplements are consumed and work from within.
