Collagen for Skin Rejuvenation: A Real Effect or a Beauty Industry Myth?

Skin - the largest organ of the human body and a main indicator of beauty - is receiving more and more attention, especially when it comes to its rejuvenation and healthy appearance. Beyond daily beauty routines, we often hear the word collagen - a protein often referred to as the "structural support" for youthful skin.

Today, we frequently encounter collagen food supplements and collagen-containing skin care products that promise improved elasticity, firmness, and radiance. However, as the popularity of these products grows, the question becomes more relevant: does collagen really work, or is it just another marketing wave?

What is Collagen and Why Does Its Amount Decrease?

Imagine collagen as the invisible framework of the skin that gives it firmness, elasticity, and radiance. This protein is the most abundant in our body - especially in the skin, bones, muscles, and tendons. It makes up about 30% of all proteins and more than 75% of the skin's structure.

There are 28 types of collagen, the most common of which are:

• Type I, which makes up about 90% of the body's collagen and is responsible for the strength of the skin, hair, bones, and tendons.

• Type II is important for the health of joints and cartilage.

• Type III supports the structural integrity of hollow organs and tissues (e.g., the intestines, uterus, and blood vessels).

With age, starting at around 25, the body's production of collagen decreases, and we lose about 1% of it every year. This process is also accelerated by environmental factors: UV rays from the sun, air pollution, dehydration, stress, and others.

The result? Loss of skin firmness, reduced elasticity, wrinkles, and a relaxed appearance.

How Do Oral Collagen Supplements Work?

Many people think that a collagen supplement simply replenishes the body's depleted reserves, but in reality, its effect is much broader. When you take hydrolyzed collagen (in the form of peptides), it is easily absorbed into the blood. These peptides reach the deep layers of the skin, the dermis, where they signal the body to start synthesizing its own collagen, elastin, and hyaluronic acid. This natural reaction restores the skin from within, improves its structure, and accelerates regeneration.

For a better effect, Vitamin C is essential for collagen synthesis. Therefore, if you are taking a collagen supplement, make sure you are also taking Vitamin C with it—either in a complex or separately.

Clinical Studies on Collagen: Are Supplements Truly Effective?

Numerous clinical studies and meta-analyses confirm that the regular intake of collagen peptides (usually for 4 to 12 weeks) has a significant positive effect on the skin:

• Hydration: The skin becomes noticeably hydrated and smooth.

• Elasticity: The firmness and elasticity of the skin increase significantly, which is the main prerequisite for maintaining a youthful appearance.

• Wrinkle Reduction: Studies show that the volume of fine and deep wrinkles is reduced.

• Firmness: The density and thickness of the deep layers of the skin increase, and the skin's structure improves.

Oral Collagen vs. Collagen-Containing Creams?

The beauty industry offers countless cosmetic products containing collagen, but a question remains: do they work correctly?

The collagen molecule is quite large, and when applied to the skin's surface, it cannot penetrate the deep layers of the epidermis. Accordingly, creams only temporarily moisturize the skin and do not stimulate internal regeneration.

In contrast, oral collagen works from the inside. It makes fundamental changes in the inner layers of the skin, improving the condition of not only the face but the entire body's skin. As a bonus, it also has a positive effect on hair, nails, and joints.

To the question "Which is better?" - the answer is simple: oral collagen.

Safety and Recommendations

Collagen supplements, especially in hydrolyzed form, are considered safe and easily assimilated by the body. However, here are some important recommendations:

• Choose a certified product that has a third-party confirmed certificate for quality, safety, and production processes.

• Find out the origin - if you have an allergy (for example, to fish), carefully check where the collagen in your chosen food supplement is derived from.

• Consult with a doctor during pregnancy, lactation, or if you have any chronic disease.
  

There is no single molecule that rejuvenates the skin - this is the result of systemic care, and collagen has a special place in this system. Collagen is not a magic pill, but when used wisely and regularly, it becomes a loyal ally of the skin, providing structural support, natural radiance, and a skin rejuvenation effect.
