Collagen is the most important structural protein in our connective tissue – crucial for skin elasticity and the strength of bones, tendons, and joints. As we age, the body's own collagen production decreases, which can manifest as wrinkles, sagging skin, or joint problems. In recent years, the trend toward collagen powders, masks, and other dietary supplements has increased dramatically, often accompanied by social media hype. But what's really behind this trend, and how effective are these products for our skin? We've investigated. Prof. Dr. med. Hisham FansaWe asked our renowned plastic surgeon for his assessment.

Prof. Fansa, why is collagen so important for our body?

Collagen is an essential component of the so-called extracellular matrix, that is, everything that is not part of the cells. Collagen is a crucial framework for our connective tissue. We distinguish quite a few different types of collagen in the body – depending on their function.

Collagen is currently all the rage – in powder form, masks, and creams. How effective are these products really?

To be honest, there is no evidence of effectiveness, neither for collagen taken orally nor for collagen applied to the skin.

Are there medically proven alternatives for increasing collagen production?

Ah, in the end it's quite simple: the body is a marvel. It generally functions well if you don't stress it. Therefore, avoid sun exposure without a sufficient sun protection factor (SPF), quit smoking, avoid alcohol, exercise in a healthy environment, eat a balanced diet, and get enough sleep. Then your body has the best chance of staying healthy. People with skin conditions, very dry skin, or very oily skin benefit from good dermatological care; however, often simply avoiding irritants is enough.

Which procedures are suitable for long-term results against wrinkles and sagging skin?

You can subtly reduce expression lines with Botox. Expression lines are wrinkles caused by facial muscle movement. With a little... hyaluronic acid fillers or Autologous fat It is possible to counteract age-related volume loss, but be careful: too much doesn't look good, but artificial.

In recent years there has been PRP (Platelet-rich plasma, also known as the "vampire facelift") has become established. Several studies describe local collagen improvement, but whether it actually works varies from person to person.

From a certain age, one can consider a Eyelid lift on the upper eyelid and/or lower eyelid or a natural one Facelift and Neck lift Think about it. The results are more natural and lasting than with excessive use of fillers. The new naturalness is the trend of the times.

Why do so many people resort to collagen supplements, even though their effectiveness is limited – what advice do you give to patients?

I think many people succumb to the allure of marketing for such products. It would be great if they worked, of course. But honestly: save your money for a sensible and lasting procedure performed by a good and experienced plastic surgeon.

And finally ... Collagen supplements and masks can be helpful, but their effects are usually subtle and short-lived. Those seeking significant, lasting results benefit from medically sound, targeted treatments.
