Silymarin

Product Description

Silybum Marianum Fruit Extract is a highly purified botanical active, standardized for a high content of Silymarin, the renowned protective molecule from Milk Thistle. It is a premier choice for dermo-cosmetic formulations, acting as a powerful antioxidant and anti-inflammatory agent. Its key advantage is its clinically-proven ability to protect the skin from photo-damage by neutralizing free radicals generated by UV exposure. In a market where consumers are seeking potent, natural solutions for environmental protection and soothing, this extract offers a time-tested and science-backed ingredient for advanced anti-aging and skin-defense products.

Product Uses

This powerful antioxidant is a cornerstone for a wide range of protective and restorative skincare:

• Protective Skincare: Ideal for daily-use serums, moisturizers, and "anti-pollution" formulas designed to shield the skin from environmental stress.
• Sun Care: A key ingredient in sunscreens and after-sun products to provide robust antioxidant defense against UV-induced damage and to soothe the skin.
• Problem Skin: Used in treatments for sensitive or blemish-prone skin due to its strong anti-inflammatory and calming properties.
• Anti-Aging: Incorporated into anti-aging lines to help protect the collagen matrix and reduce signs of photoaging.

Formulation Suggestions

The recommended dosage is between 0.1-1.0%. As a powder with poor water solubility, it must be pre-dissolved in a suitable solvent system, such as a blend of glycols (e.g., propanediol, butylene glycol) or ethanol, before being added to a formulation. Gentle heating can aid dissolution. It is best incorporated into the oil phase of an emulsion or into an anhydrous system. For enhanced antioxidant benefits, it works synergistically with other antioxidants like Vitamin C and E.
