Strength and Durability: Silk fibroin is known for its exceptional tensile strength, making it a valuable material for various applications, including medical sutures, tissue engineering, and textile production.

Soft and Luxurious Texture: Silk fibroin has a soft and smooth texture, making it a preferred material for high-end clothing, lingerie, and bedding.

Moisture Retention: Silk fibroin can retain moisture, which is beneficial for skincare products, as it can help keep the skin hydrated.

Biomedical Applications: Silk fibroin is used in various biomedical applications, such as tissue engineering, drug delivery, and as a substrate for cell culture due to its biocompatibility and strength.

UV Protection: Silk fibroin has natural UV-protective properties, which makes it useful in clothing and cosmetics that offer sun protection.

Wound Healing: Silk fibroin-based dressings can promote wound healing due to its antimicrobial properties and ability to maintain a moist wound environment.


Cost: Silk fibroin is relatively expensive to produce compared to other materials, primarily because it is derived from silkworms and requires a labor-intensive process.

Allergenic Potential: Although silk is generally hypoallergenic, some individuals may still be allergic to it. This can lead to skin irritation or allergies in sensitive individuals.

Limited Supply: The production of silk fibroin is limited by the availability of silkworms, and there may be fluctuations in supply due to various factors such as weather conditions and market demand.

Environmental Impact: While silk is biodegradable, the production process can have environmental impacts, especially if not managed sustainably. Pesticides and water usage in silkworm farming can be problematic in some regions.
