Collagen plays a huge role in making your skin radiant, healthy, and firm. Find out how this protein acts as a foundation for your skin health by increasing its elasticity and resilience. 

Collagen supports the skin tissue, ensuring its elasticity, firmness, and resilience, like a flexible but tenacious network that works silently beneath the surface. Structurally, collagen is a proteincomposed of three chains of amino acids intertwined to form a triple helix. These helices aggregate together to form fibrils, which in turn organise themselves into collagen fibres: true microscopic pillars of our skin. Intertwined in a three-dimensional web, they are located under the epidermis, the outermost layer, like a mattress, capable of supporting the tissue and keeping it compact but flexible. 

And that's not all: there is not just one type of collagen! There are at least 28 types in our body, each with a specific function. Not all of them actively participate in maintaining the beauty of our skin; the real protagonists of the skin are:

• Type I collagen- the most abundant
• Type III collagen - present in smaller quantities but still essential for joint cartilage
• Type VI collagen - contributes to the proper functioning of muscle tissue

In our body, collagen is like a silent and tireless architect, working behind the scenes to ensure stability, form, and functionality. 

Just like a superhero working behind the scenes, collagen is your skin's greatest silent ally. When collagen is present in adequate quantities, the skin appears radiant, smooth, and vital, free of marked wrinkles or fine lines. Unfortunately, however, from the age of 25 onwards, our body begins to slow down its collagen production. During early adulthood, endogenous collagen synthesis decreases, while metalloproteinases, endogenous enzymes that break down collagen, continue their activity. 

The result of this slow imbalance becomes increasingly evident year after year as the skin loses tone, the first wrinkles appear, and the skin structure begins to sag. These are the visible signs of a weakening internal architecture. And it is not only age that undermines this structure.  

There is a whole world of external factors that affect our skin, known as the exposome. These include:  

• Sun exposure
• Smoking
• Air pollution
• Environmental and behavioural conditions that accelerate collagen degradation

Understanding the role of collagen in skin health means looking beyond the mirror and learning to protect what lies beneath: the biological scaffolding on which lasting beauty is built. 

Collagen comes from simple but valuable building blocks: amino acids that act as small “bricks” essential for building proteins that keep the skin toned, firm, and resistant. When the supply of these elements is scarce, collagen production slows down, and our skin suffers.  

However, the good news is that there are several ways to support the skin tissue to produce more collagen naturally and strategically.  

• A balanced diet with foods rich in vitamin C and other antioxidant vitamins, such as kiwis, citrus fruits, and tomatoes, can effectively support endogenous collagen synthesis.
• Minerals like zinc and copper help to protect the skin from damage caused by free radicals, the formation of which is greatly enhanced by exposure to the sun*.
• Dietary supplementation, often through drinks enriched with hydrolyzed collagen or specific peptides, provides amino acids that the body can reuse when necessary. It is important to remember that this strategy requires time and careful supervision by a professional to be truly effective. 
• A targeted skincare routine can protect existing collagen and stimulate the skin to produce more. This is at the heart of the innovation developed by [ comfort zone ], which, thanks to the support of its in-house laboratories and a scientific committee of excellence, has been able to develop the new and innovative Longevity Collagen+ Serum by /skin regimen/Lx.

As we age, our ability to produce collagen slows down. To make matters worse, the exposome comes into play, i.e. the combination of external factors such as stress, pollution, smoking, lack of sleep, and poor diet, accelerating collagen’s degradation. All these factors lead to a single result: duller, less toned skin with visible signs of aging.  

To counteract these effects, Comfort Zone has developed a complete solution: the new Longevity Collagen+ Serum by /skin regimen/Lx, a redensifying serum with an immediate filler effect. 

The secret of this innovative treatment lies in the synergy between two highly effective complexes: 

- Longevity Complex™ 

- Collagen Pro Complex

The former aims to protect the skin from daily attacks by the exposome, thanks to a pool of specific active ingredients that act on the mechanisms that accelerate aging and are linked to the exposome. These includemyrtle berry extract, obtained from plants grown according to the principles ofregenerative ​organic agriculture,spinach extract, and Tephrosia purpurea extract, alongside carnosine.

The serum's action is completed by the innovative Collagen Pro Complex, formulated to actively stimulate the production of new collagen. It contains low molecular weight hydrolyzed collagen and lemon balm extract, rich in rosmarinic acid and obtained from plants grown at EROC, the European Regenerative Organic Centre in Parma. Finally, the formula is enriched with a biomimetic peptide structure and acacia collagen, a plant-based alternative to animal collagen.

This rich pool of functional ingredients in Collagen Pro Complex gives this innovative complex the ability to boost type I and type III collagen in our skin by 40.6%*, and its synergy with Longevity Complex is what defines the ability of /skin regimen/Lx's new Longevity Collagen+ Serum to have an immediate redensifying and filling effect**.
