What is collagen and why is it so important for the skin?
Collagen is the primary structural protein in the human body. It makes up approximately 70% of the dry weight of the dermis and is responsible for its strength, resilience, and elasticity.
In young skin, collagen fibers form a dense and organized network that acts like a natural scaffolding supporting the tissues. This makes the skin firm, taut, and resistant to wrinkle formation.
With age, however, collagen production gradually declines.
It is estimated that:
- after 25 years of age, collagen production begins to decrease
- after 40 years of age, the rate of its loss significantly accelerates
- collagen fibers become thinner and less organized
This is precisely why skin may lose elasticity over time, and the first signs of aging appear on its surface.
Natural collagen – how does it differ from other forms of collagen?
In cosmetology, various forms of collagen can be found. The most common are:
- hydrolyzed collagen
- native (natural) collagen
- collagen peptides
Natural collagen, also called native collagen, retains its triple-helical spatial structure. It is this structure that is characteristic of collagen found naturally in the body.
Thanks to this, it:
- forms a delicate protective film on the skin's surface
- helps limit water loss from the epidermis
- supports the feeling of smoothed and moisturized skin
In modern skincare, bioactive natural collagen, which retains its structure and biological properties, is increasingly used.
How does collagen affect the appearance of the skin?
Regular use of collagen-containing products can support several important aspects of skin condition.
1. Skin hydration
Collagen has the ability to bind water. This helps maintain proper skin hydration levels and improves its comfort.
2. Smoothing of the skin surface
The protective film created by collagen can make the skin appear smoother and softer to the touch.
3. Support for elasticity
Well-hydrated skin is more resilient and less prone to losing firmness.
4. Comfort for sensitive skin
Collagen is a well-tolerated ingredient by the skin, which is why it is often used in the care of dry, mature, or sensitive skin.
Can collagen penetrate the skin?
One of the most frequently asked questions is whether collagen can penetrate the epidermal barrier.
In cosmetic practice, collagen primarily acts on the skin's surface, where it:
- supports its hydration
- helps limit water loss
- improves the feeling of smoothness
However, this does not mean that its role is small. Properly hydrated skin functions better and looks healthier.
Therefore, collagen is often an element of comprehensive care, which combines:
- external care
- skin support from within through diet and supplementation
Skin care from the outside and inside
More and more people are paying attention to an approach referred to as beauty in & out.
It consists of combining:
✔ appropriate skincare
✔ a healthy diet
✔ supplementation supporting skin condition
In practice, this can mean combining:
- cosmetics containing collagen
- dietary supplements containing collagen or ingredients that support its production
- daily skincare routine
This approach supports the natural regeneration processes of the skin.
What does a conscious skin care routine look like?
The skin renewal cycle, which lasts approximately 28 days on average, is also increasingly being discussed.
During this time, epidermal cells undergo regeneration and are replaced by new ones.
Therefore, skin care should be:
- regular
- consistent
- tailored to the skin's needs
In practice, it may include:
- cleansing the skin
- toning or using a mist
- applying collagen products
- moisturizer or regenerating cream
Consistency in skincare is one of the most important factors influencing the appearance of the skin.
