Skin Perfection Leucidal Liquid is a water-soluble natural preservative derived from radish root, designed for use in DIY skincare formulations such as lotions, serums, creams, and body lotions. This 16-ounce product serves as an alternative to synthetic preservatives, offering a plant-based option for extending the shelf life of handmade cosmetic preparations. The active component, leucidal, is produced through fermentation of radish root, which provides antimicrobial properties that help maintain product stability without relying on harsh chemicals.

This preservative is suitable for a range of water-based formulations, including those containing vitamin C serum or hyaluronic acid body lotion, as it integrates smoothly into oil-in-water emulsions. It is intended for formulators who prioritize natural ingredients in their skincare creations, such as those making serums, creams, or lotions at home. The liquid form allows for easy incorporation during the cooling phase of production, ensuring even distribution without altering the texture or scent of the final product.

The formula is gentle and compatible with sensitive skin types, as it does not contain parabens, formaldehyde, or other common synthetic preservatives. It is particularly useful for those seeking a mild, plant-derived option to protect against microbial growth in water-containing products. The product should be used according to recommended usage rates, typically between 2% to 4% of the total formulation weight, to achieve effective preservation without compromising product integrity. This neutral, functional ingredient supports the creation of stable, long-lasting skincare preparations while maintaining a focus on natural composition.
