Active ingredients
Keratin amino acids, also known as keratin hydrolysate, are a natural ingredient derived from animal hair or nails, most often from keratin-containing sources such as sheep (wool) or cattle. This ingredient is rich in essential amino acids that help strengthen and repair hair, making it healthier and shinier. Keratin amino acids improve moisture retention, give hair elasticity, reduce breakage, and make combing easier. Using this ingredient in cosmetics can achieve excellent results, especially when aiming to restore damaged or dry hair. In addition, it is an excellent tool for skin care, as amino acids help restore the skin barrier and give it radiance. The naturalness and functionality of keratin amino acids make them extremely valuable ingredients in beauty products.
Purpose and Benefits
The effect of keratin amino acids in cosmetic products lies in their ability to act at the cellular level. These tiny molecules, which make up the keratin protein, penetrate deep into the skin or hair, where they actively work to restore structure and strengthen natural protection. When skin or hair is stressed by environmental factors such as sun, heat, or chemicals, keratin amino acids act as “building blocks” that fill in damaged areas and help restore lost integrity. For hair, this substance is like an elixir of life. It helps restore keratin layers that naturally break down due to dyeing, heat exposure, or environmental pollution. The result? Hair becomes softer, stronger, less prone to breakage, and shines as if reborn. In skin care, keratin amino acids stand out for their moisturizing properties. They not only help retain skin moisture but also support elasticity, giving the skin smoothness and softness. It is a special ingredient for those seeking radiant, healthy skin. Another unique property of this ingredient is its ability to help cosmetic ingredients work synergistically. Used in combination with other active components, keratin amino acids enhance the overall effectiveness of the formula. They create a protective layer that not only protects against moisture loss but also helps to better absorb other nutrients. It is an ingredient that not only adorns but also takes care of deeper aspects of beauty.
Security Information
Keratin amino acids have a high safety profile. Clinical studies show that this ingredient is generally well-tolerated by most skin and hair types. Although side effects are rare, some people may experience allergic reactions such as itching or redness. It is important to perform an allergy test before using new cosmetic products, especially for individuals with sensitive skin. Regulatory authorities, such as the European Cosmetics Regulation, recognize keratin amino acids as safe cosmetic ingredients. It is recommended to use products containing this ingredient according to the manufacturer’s instructions to ensure maximum benefit and minimize potential reactions.
Sustainability and Extraction
Keratin amino acids, while possessing beneficial properties, pose certain challenges in terms of sustainability and ethics. Most of them are derived from animals such as sheep or cattle, which can raise concerns about animal welfare and resource utilization. The sources from which keratin is obtained often rely on intensive agricultural practices that can have a negative impact on the environment, such as soil erosion and water pollution. Furthermore, raising animals requires significant resources, making it important to consider alternative, sustainable sources. Some manufacturers strive to ensure that their products are sourced from ethical and environmentally friendly sources, but consumers should be cautious and look for certifications that confirm this approach. Thus, while keratin amino acids can be effective hair and skin care components, their production process requires thorough evaluation, considering environmental and social aspects. Keratin amino acids are a valuable ingredient with many beneficial properties. These natural amino acids help restore and strengthen hair structure, making it stronger and healthier. This is especially beneficial for those whose hair suffers from dryness or damage due to chemical treatments or environmental factors. In addition, they have moisturizing properties that help not only hair but also skin. Keratin amino acids work great when combined with other active ingredients, helping to create effective formulas to restore a natural beauty look. These active ingredients penetrate deeply and contribute to the healthy appearance of skin and hair, giving them shine and elasticity.
Products
Keratin amino acids are frequently used in various cosmetic products for hair and skin care. Hair shampoos and conditioners, such as Innisfree’s Camellia Essential Hair Oil and Mise-en-scène’s Perfect Repair Serum, are excellent for those looking to restore damaged hair. These amino acids are also found in masks and serums, such as Laneige’s Hair Sleeping Mask, which helps to hydrate and revitalize hair overnight. In the field of skin care, products like Dr. Jart+’s Ceramidin Cream and COSRX’s Advanced Snail 92 All in One Cream use keratin amino acids to improve skin elasticity and moisture retention. Other categories, such as face and body oils, may also contain this ingredient, strengthening the skin barrier and providing a feeling of softness.
