Keratinoid

Keratinoid is a term used in dermatology to describe a substance that resembles keratin, a protein found in the skin, hair, and nails. Keratin is a structural protein that provides strength and durability to these tissues. Keratinoids are often used in cosmetic and dermatological products due to their ability to mimic the properties of keratin, such as enhancing skin hydration, improving skin texture, and promoting wound healing.

Keratinoids can be derived from various sources, including plant-based materials like wheat, rice, and soy, as well as animal-based sources such as silk and wool. These substances are typically extracted and purified to create a form that can be incorporated into skincare and hair care products. The most common keratinoid used in cosmetics is hydrolyzed keratin, which is a form of keratin that has been broken down into smaller peptides.

The use of keratinoids in skincare products is based on the belief that they can help to repair and strengthen the skin's natural barrier, improve moisture retention, and reduce the appearance of fine lines and wrinkles. They are often included in moisturizers, serums, and treatments for dry, damaged, or aging skin. Additionally, keratinoids are sometimes used in hair care products to improve hair strength, elasticity, and shine.

While keratinoids are generally considered safe and well-tolerated, it is important to note that individual reactions may vary. As with any cosmetic or dermatological product, it is recommended to perform a patch test before using a new product containing keratinoids to check for any adverse reactions. As always, consulting with a healthcare professional or dermatologist is advisable for personalized advice and treatment.
