Why is collagen so important for our skin?

What is collagen and why is it so important?

Collagen is a long chain of amino acids that forms strong fibers that create the structure of skin, tendons, bones, and other tissues. In the skin, it works in tandem with elastin and hyaluronic acid to provide strength, elasticity, and high levels of moisture.

With age, starting at around 25–30 years old, collagen synthesis slows down and its fibers become less elastic. This leads to the appearance of wrinkles, loss of elasticity, and dry skin. In addition, negative external factors (ultraviolet rays, stress, smoking, poor nutrition) accelerate the destruction of the collagen framework.

Types of collagen in cosmetics and supplements

• Animal collagen — obtained from animal tissues (usually pigs). Its molecules are large, so it mainly works on the surface of the skin, creating a protective film and retaining moisture.
• Marine collagen — extracted from the skin and bones of fish. Its structure is closer to that of human collagen and is more easily absorbed, which is why it is particularly valued in cosmetology and nutraceuticals.
• Plant collagen — this is not actually a protein, but plant proteins that have a similar effect to collagen. They stimulate the production of the body’s own collagen and elastin.

Hydrolyzed collagen is often used in cosmetics — its molecules are broken down into small fragments that penetrate the skin better and work more effectively.

Benefits of collagen for the skin

• Moisturizing and protection: Collagen forms a thin film on the skin’s surface that retains moisture and protects against drying out.
• Firmness and elasticity: Collagen supports the skin’s structure, making it denser, smoother, and tighter.
• Wrinkle smoothing: Fills in fine lines, evens out skin texture and tone.
• Restoration and regeneration: Accelerates the healing of wounds, cuts, burns, and helps with post-acne and other damage.
• Lifting effect: With regular use of collagen products, the skin becomes more elastic and the appearance of age-related changes is reduced.
• Strengthens hair and nails: Collagen is involved in the formation of keratin, making hair and nails stronger and healthier.

How to replenish collagen deficiency?

• Japanese cosmetics with collagen: creams, masks, serums that moisturize, soften, and protect the skin.
• Japanese dietary supplements: hydrolyzed collagen in capsules, powders, or drinks helps maintain protein levels from within, improving the condition of the skin, hair, nails, and joints.
• Synthesis stimulators: vitamin C, retinol, peptides, and antioxidants in the composition of the products enhance the production of your own collagen.

When to start using collagen?

It is recommended to include collagen products in your skincare routine from the age of 25–30, especially if your skin is prone to dryness or you notice the first signs of loss of elasticity. For normal or oily skin, start at 30–35 years old.

Collagen is not just a trendy ingredient, it is the foundation of your skin’s youth and health.
