Dry skin in winter: collagen to the rescue!

Winter is a dreaded season for our skin. The biting cold, dry wind and indoor heating create the perfect cocktail for weakening the skin barrier. The result: skin that pulls, peels and loses its radiance. But did you know that collagen, an essential protein in our skin, can play a key role in keeping it hydrated and supple? Let's delve into the mechanisms of dry skin and discover how collagen can be your ally this winter.

Understanding dry skin: a common winter problem

The skin is our first line of defense against external aggression. Its protective barrier, made up of lipids and cells, plays an essential role in retaining water in the epidermis. In winter, this barrier is put to the test:

• Cold slows blood circulation, reducing the supply of essential nutrients to the skin.
• Dry air caused by heating sucks moisture from the skin, leaving it dehydrated.
• Winter habits such as hot baths and the use of aggressive cleansing products further weaken the skin barrier.

The result? Rough skin, prone to irritation and sometimes even cracking. It's essential to reinforce this barrier and support the skin's internal mechanisms to keep it hydrated and elastic.

The role of collagen in the skin: structure and support

Collagen is a structural protein found in the dermis, the deepest layer of the skin. It acts like a supportive mattress, providing firmness and elasticity. From the age of 25, our natural collagen production diminishes, leading to a loss of tone and increased fragility.

In winter, this natural degradation is amplified by external aggressions. Skin low in collagen is less able to retain water and regenerate after damage. Collagen therefore contributes indirectly to skin hydration by preserving its integrity and promoting cell renewal.

Factors influencing natural collagen production

Several factors, both internal and external, have an impact on collagen production:

• Internal factors :
  • Natural aging, which progressively reduces collagen synthesis.
  • Oxidative stress caused by free radicals, which destroy collagen fibers.
• External factors :
  • UV exposure, which destroys existing fibers even in winter.
  • Pollution, smoking and a nutrient-poor diet.

To limit this degradation, it is crucial to adopt protective habits and provide the skin with the elements it needs to produce collagen.

Supporting your skin in winter: practical advice

Fortunately, there are things you can do to keep your skin supple and moisturized despite the rigors of winter. Here are a few practical tips:

External moisturizing

• Opt for creams rich in moisturizing agents such as hyaluronic acid or ceramides.
• Choose gentle products that respect the skin barrier.
• Avoid excessively hot showers, which can delipidate the skin.

Nutrition

• Include in your diet sources of vitamin C (kiwi, citrus fruits) and zinc (nuts, seeds), essential for collagen synthesis.
• Supplement with collagen to support internal mechanisms.

Focus on marine collagen peptides from Laboratoire Dielen

Promerim® marine collagen peptides are exclusive to the Dielen range, and are obtained via a hydrolysis process for which we alone have the secret. Thanks to this process, these collagen peptides have a particular composition and structure, which is the source of their properties.

💡 What makes our peptides unique?

• High bioavailability: Promerim® collagen peptides are of very low molecular weight (VLMW ), between 300 and 1,700 Daltons. Their small size makes them highly bioavailable, unlike collagen, which is a large protein that cannot be assimilated as it is. This facilitates their digestive absorption.
• Benefits studied at low doses: several studies have demonstrated the benefits of Promerim® collagen peptides from a daily intake of 1 to 2 tablets. This sets them apart from other collagen powders packaged in jars or sachets, which often require higher, more expensive doses. Thanks to PROMERIM® peptides, high doses of hydrolyzed collagen are not necessary - 2 tablets a day are all you need!
