What do we know about collagen? Why is it important for well-being and skin care?

When it comes to skin care and well-being, collagen takes center stage. This protein forms the foundation of our skin, connective tissue, and bones, and it is responsible for the skin’s firmness, elasticity, and healthy appearance.

However, with age, the body’s collagen levels naturally decline, leading to wrinkles, loss of tone, and other signs of aging. Let’s explore why collagen is so important for the skin, how to support it, and what to do to keep the skin well-groomed for as long as possible.

1. What is collagen and its role in the skin?
Collagen is a protein that makes up about 30% of all proteins in our body. It forms a kind of framework that supports the skin’s structure. In the dermis (the deeper skin layer), collagen fibers provide:

• Firmness and density of the skin

• The ability of the skin to stretch and return to its original state

• Wound healing and cell regeneration

Without enough collagen, the skin becomes less elastic, wrinkles appear, and smoothness is lost.

2. Why does collagen decrease?
After the age of 25, the body gradually loses collagen — about 1–2% per year. This process accelerates due to factors such as:

• Age: Collagen synthesis slows down and existing protein breaks down faster.

• Ultraviolet radiation: Sun exposure damages collagen fibers, causing photoaging.

• Poor nutrition: Lack of protein, vitamins, and antioxidants weakens the skin’s ability to regenerate.

• Stress and bad habits: Smoking, alcohol, and chronic stress reduce collagen production.

3. Signs of collagen deficiency

• Wrinkles and reduced skin firmness

• Dryness and flaking

• Loss of facial contour definition

• Slow healing of minor skin damage

4. How to maintain collagen levels

• Proper nutrition
  Include in your diet:

  • Protein-rich foods (chicken, fish, eggs)

  • Vitamin C (citrus fruits, kiwi, bell peppers)

  • Zinc and copper (seafood, nuts)

  • Antioxidants (berries, green tea)

• Collagen supplements
  Studies confirm that hydrolyzed collagen taken orally improves skin hydration and firmness.

• Skin care
  Use products with active ingredients that stimulate collagen production, such as:

  • Retinol

  • Peptides

  • Hyaluronic acid (helps collagen work more effectively)

• Sun protection
  SPF creams are essential to protect collagen fibers from UV damage.

• Regular procedures
  Treatments such as microcurrents, lasers, and microneedling stimulate collagen synthesis.

5. Myths about collagen

• “Collagen can only be obtained from food”: True, but supplements and protection are also crucial.

• “Collagen creams make skin firm”: In reality, collagen in creams mainly moisturizes the surface; deeper stimulation requires active components.

6. Conclusion: Collagen — the foundation of healthy, radiant skin
Collagen plays a key role in maintaining skin well-being. Although its levels decline with age, proper nutrition, quality skincare, supplements, and protection can slow aging and preserve smooth, firm, and glowing skin.
