Active ingredients

Keratin is a natural protein that forms the foundation of our hair, nails, and skin. Its structure is composed of amino acids, which together create strong and resilient fibers. In cosmetic products, keratin is most often used to restore and strengthen hair, giving it shine, elasticity, and protection from damage. This ingredient can be obtained naturally from animals (such as hair or feathers) or through synthetic methods. Naturally derived keratin is often an ideal choice because it better matches our body’s needs. By using keratin in cosmetics, we can achieve not only more beautiful and healthier hair, but also improve its structure in the long term.

Purpose and Benefits

The power of keratin lies in its ability to penetrate damaged layers of hair or skin and effectively restore them. It’s not just a surface improvement – keratin works deeply, strengthening hair from within and filling in damaged fiber parts. The result? Hair becomes softer, smoother, and shinier, as if it has regained its vitality. When hair ends are prone to split ends or hair looks depleted from daily heat and chemical exposure, keratin becomes a true savior, providing protection and long-lasting shine._x000D_

Skin can also benefit from the advantages of keratin. This protein helps strengthen the skin’s barrier function, maintains its elasticity, and resistance to environmental influences. By using products with keratin, the skin can become smoother, protected from moisture loss, and its overall tone – healthier. In addition, keratin is naturally compatible with the human body, so the risk of causing irritation or allergic reactions is minimal, which is especially important for people with sensitive skin._x000D_

Interestingly, keratin is not just about protection or repair – it also improves the texture of cosmetic products. Shampoos, conditioners, or creams with this ingredient often have a smoothness and pleasant glide, making use a pleasant experience. Each product with keratin, like an invisible hand, ensures subtle but effective care, which allows you to feel like a self-confident personality.

Security Information

Keratin, while considered a safe ingredient in many cosmetic products, can cause some adverse reactions. Some people may experience allergies, irritation, or sensitivity, especially if their skin is sensitive or prone to allergies. Therefore, it is important to perform a skin test before using products containing keratin, especially those that have not been used for a long time. Regulatory authorities, such as the European Union, closely monitor cosmetic ingredients, including keratin, and ensure that its use complies with safety standards. It is recommended to follow the manufacturer’s instructions and recommendations for use to minimize the risk of any adverse reactions. Nevertheless, most users experience positive effects from keratin, which is why this ingredient remains popular in the cosmetics industry.

Sustainability and Extraction

This protein, while highly valuable, raises certain sustainability and ethical concerns. Naturally derived keratin is often extracted from animals such as cows or chickens, which raises concerns about animal welfare. At the same time, synthetic production methods, which provide a more environmentally friendly alternative, are still underdeveloped. Furthermore, keratin production can have a negative impact on the environment if irresponsible extraction practices are carried out. Most sources emphasize that more attention should be paid to sustainable sourcing and production, ensuring that the process does not harm either animals or our planet. Environmental standards and social responsibility should be a priority in all keratin supply chains so that consumers can feel confident about their choices.

Products

Cosmetic products in which this protein is often found include hair care products, such as shampoos and conditioners, designed to restore and strengthen hair. For example, the Kérastase line includes products rich in keratin, which helps to repair damaged hair and add shine. It is also worth mentioning the brands Mise en Scene and Innisfree, which offer keratin-containing hair oils and masks for intense hydration and improved hair structure. In addition, keratin can also be found in skin care products, such as moisturizing creams and serums, which help restore skin elasticity and protect it from harmful factors. These products often have a soft texture and excellent nourishing properties, allowing the skin to look healthier and more radiant.
