What is collagen?

Collagen is an essential protein that is responsible for the structure, firmness and elasticity of the skin. With increasing age, the natural production of collagen decreases, which leads to the formation of wrinkles and sagging skin. Collagen in skin care products aims to slow down this process and improve the skin’s structure.

Benefits of collagen for the skin

  • Improving skin elasticity: Collagen supports the elasticity of the skin and helps to keep it firm and youthful.
  • Reduction of wrinkles: By promoting skin density, collagen products can reduce the appearance of fine lines and wrinkles.
  • Supporting skin regeneration: Collagen can improve the skin’s ability to regenerate and contribute to a healthier, more radiant complexion.

Possible side effects

Collagen is generally well tolerated. Allergic reactions are rare with topical application, but cannot be ruled out. When taking collagen preparations orally, possible interactions and individual intolerances should be taken into account.

Application recommendations

Collagen can be applied topically in the form of creams, serums and masks or as a dietary supplement. For an effective skincare routine, collagen should be used daily, ideally in combination with other anti-ageing ingredients such as vitamin C and hyaluronic acid.

How not to use it

There are no specific restrictions on the use of collagen in skin care. However, care should be taken to choose products with high-quality collagen and to use them according to the manufacturer’s instructions.


1. can collagen reverse skin ageing? Collagen can reduce the signs of skin ageing, but not reverse them.

2. is collagen in skin care products vegan? Many collagen products are of animal origin, but there are also plant-based alternatives.

3. how quickly does collagen work in skin care? Results may vary, but visible improvements can often be observed after a few weeks of regular use.


Collagen is a key ingredient for effective anti-ageing skin care. Thanks to its ability to promote skin elasticity and reduce wrinkles, it can make a significant contribution to maintaining a youthful complexion. Regular use, combined with other skin care ingredients, can significantly improve skin health and appearance.
