The real effects of collagen in cosmetics

Collagen is a popular ingredient in cosmetics. Supplements containing collagen are even said to support your skin from the inside. But is this actually true?

There’s collagen in almost everything: tablets, creams and serums. Collagen is the substance that holds the body together and therefore also plays a role in skin aging. However, consumers like myself are uncertain: do collagen care products and supplements really work or is all just marketing blah blah? I’ve talked to dermatologist Dr. Liv Kraemer to find an answer to this question.

Why does collagen play such a major role in skincare?
Dr. Liv Kraemer, expert on dermatology, skincare and skinfood:
Collagen consists of amino acids and is essential for the elasticity of our skin. If you look at it under the microscope, it has the shape of a triple helix – It looks a bit like a spring. When it loses its elasticity, it expands. This is exactly what happens to our skin: it stretches. There are 28 types of collagen in total, but not all of them have been researched in depth.

Can I support my skin's collagen production with nutrition?
Yes, a balanced diet helps. Eat foods that are rich in vitamin C and amino acids and have a high glutathione content such as broccoli. If you have trouble doing this, supplements are also an effective option.

What effect can I expect from skin care products containing collagen?
Collagen that you apply to your skin from the outside only provides a short-term and purely superficial effect. It acts as a corset that supports your skin, which is great if you’re getting ready for a date, but won’t last long, as the collagen doesn’t reach the depths of your skin. The collagen molecule itself is too large to penetrate the surface of the skin.

How do I protect my collagen from being damaged?
The best way is to use UV protection. 80 percent of skin aging is caused by the sun. Factors such as stress, smoking and alcohol consumption also influence your collagen. Avoiding sugar also helps, as sugar reduces collagen.

As a massive Disney fan, I see the world through rose-tinted glasses. I worship series from the 90s and consider mermaids a religion. When I’m not dancing in glitter rain, I’m either hanging out at pyjama parties or sitting at my make-up table. P.S. I love you, bacon, garlic and onions.
