HYDROLYZED SERUM PROTEIN

Description

Hydrolyzed serum protein is a potent skincare ingredient derived from animal-based proteins, typically bovine serum. This bioactive compound undergoes enzymatic hydrolysis, breaking down complex proteins into smaller peptides and amino acids. These smaller molecules can more easily penetrate the skin's surface, offering enhanced bioavailability and efficacy.

The ingredient primarily functions as a moisturizing and skin-conditioning agent. It forms a protective film on the skin's surface, helping to reduce transepidermal water loss and maintain optimal hydration levels. Hydrolyzed serum protein also possesses humectant properties, attracting and retaining moisture within the skin.

Beyond hydration, this ingredient contributes to skin repair and regeneration. The peptides and amino acids it contains serve as building blocks for essential skin proteins like collagen and elastin. This can potentially improve skin elasticity, firmness, and overall texture. Additionally, hydrolyzed serum protein may offer mild antioxidant benefits, helping to protect the skin from environmental stressors.

In formulations, it is compatible with a wide range of other skincare ingredients and is suitable for various skin types, including sensitive skin. Typical concentration levels in products range from 0.1% to 5%.
