Collagen, a protein essential to our bodies, is often highlighted for its benefits to skin, hair and joints. With the arrival of summer, this natural molecule is attracting particular interest, as it is considered a major ally in preparing our bodies to face external aggressors such as UV rays, heat and dryness. But what exactly is collagen? What role does it play in the body, and how can it help us preserve our health and beauty assets over the summer months? In this article, we'd like to tell you everything you need to know about collagen before summer arrives, so you can make the most of the sunny days with complete peace of mind!
Collagen is our body's most abundant protein. It accounts for 30% of total proteins. It's a protein naturally present in all our body's structures, such as skin, tendons, bones, cartilage and ligaments. This protein is essential for tissue maintenance and strength.
In fact, collagen plays a fundamental role in the renewal of dead cells and wound healing. In particular, it ensures our skin's firmness and suppleness.
However, the production and quality of this protein diminishes from the age of 25 onwards. Many people are therefore looking for a way to produce collagen in order to maintain healthy, youthful skin.
There are around 20 types of collagen in the human body, of which only 3 are predominant in the organism:
The skin is made up of 3 layers: epidermis, dermis and hypodermis. It is present in the dermis and is associated with other protein fibers.

The sun is essential to life. For example, it enables us to synthesize our daily supply of vitamin D. However, uncontrolled exposure to the sun can be harmful, leading, for example, to premature aging of the skin.
The harmful effects are due to ultraviolet (UV) radiation, invisible to the naked eye. They damage cellular DNA. There are 3 types of ultraviolet radiation:
Every day, we are exposed to UVA and UVB rays, regardless of the weather (cloud cover, altitude). Our skin has its own defense and protection systems. But when exposure is too intense or frequent, they can become overwhelmed. The deleterious effects are both immediate and delayed.
Sunburn or solar erythema: this is a real burn. It can range from a simple redness to a second-degree burn with the appearance of blisters. Generally painful, it may require hospitalization.
Skin thickening: A natural protection phenomenon that thickens the epidermis to better block UV rays. However, it can also lead to acne.
The effects of UV rays are cumulative over the years. Their severity depends on the total dose of photons received and the quality of the individual's natural photoprotection.
Skin aging: characterized by the appearance of dry skin, deep wrinkles and irregular pigmentation.
Skin cancers: UVA and B rays oxidize the DNA of skin cells. They can cause mutations and cancerous tumors.
Our advice: The DIELEN Laboratory has formulated DIELEN® COLLAGEN which combines the main natural dermo-nutritional nutrients with structuring, moisturizing and antioxidant** properties.
Its original formula contributes to collagen formation* and protects cells from oxidative stress**.
2 capsules a day for 3 months, renewable, is recommended.
* Vitamin C supports normal collagen formation for normal skin function.
** Vitamin E helps reduce cellular oxidative stress while maintaining skin elasticity and promoting hydration.
