What Is Hydrolyzed Extensin?
Hydrolyzed Extensin is a plant-derived glycoprotein obtained from the cell walls of carrots and other root vegetables. Extensins are structural proteins that help plants stay firm and elastic. Through a process called hydrolysis, these large proteins are broken into smaller, water-soluble fragments that skin and hair can more readily absorb. Interest in plant proteins for beauty care grew in the 1970s, and by the late 1990s suppliers had refined methods to isolate and hydrolyze extensins for cosmetic use.
Production starts with washing and milling the vegetable source, followed by enzymatic or acid hydrolysis that cuts the protein into smaller peptides. The mixture is then filtered, purified and spray-dried into a fine powder or kept as a clear solution. Because it is water-soluble and has a neutral scent, formulators can easily add it to a wide range of products, including moisturizers, anti-aging creams, hydrating serums, sheet masks, hair masks, leave-in conditioners and repair treatments.
Hydrolyzed Extensin’s Cosmetic Benefits/Uses
Here is how Hydrolyzed Extensin works inside your favorite beauty formulas
- Hair conditioning – The small protein fragments cling to damaged areas along the hair shaft, helping smooth rough cuticles and reduce frizz. This gives hair a softer feel, better shine and improved manageability without weighing it down
- Skin conditioning – On skin the peptides form a light film that helps hold moisture, leaving the surface feeling hydrated and supple. This film can also give a gentle tightening effect that makes fine lines appear less noticeable, making it popular in firming and anti-aging products
Who Can Use Hydrolyzed Extensin
Hydrolyzed Extensin is generally suitable for all skin types including dry, normal, combination and oily skin. Its light film-forming action adds hydration without heaviness so even acne-prone complexions usually tolerate it. Those with extremely sensitive skin or known allergies to plant proteins should proceed with caution since any protein fragment can, in rare cases, trigger irritation.
Because it is extracted from carrots and other vegetables the ingredient is appropriate for vegans and vegetarians. No animal-derived materials are used during production.
Current safety data show no specific risks for pregnant or breastfeeding women when Hydrolyzed Extensin is applied topically. This is not medical advice and anyone who is pregnant or nursing should review their skin or hair care routine with a qualified healthcare provider to be safe.
