Leucidal SF COMPLETE is a broad spectrum protection ingredient designed for use in DIY cosmetic formulations. This 1-ounce set includes three bottles, offering a practical supply for small-batch production of serums, facial lotions, and other skincare products. The ingredient is particularly well suited for formulations containing active powders such as vitamin C (ascorbic acid) and hyaluronic acid, as it helps maintain product stability and extend shelf life without relying on harsh synthetic preservatives.

Sourced from natural fermentation processes, Leucidal SF COMPLETE provides antimicrobial and antifungal properties that help protect DIY creations against microbial contamination. Its mild formulation is compatible with a wide range of oil-in-water emulsions and water-based systems, making it a versatile choice for makers who prioritize gentle, plant-derived preservation. The ingredient does not alter the texture or clarity of finished products, allowing formulations to remain light and easy to apply. Because it is designed for broad spectrum protection, it can be used in both leave-on and rinse-off applications, including facial serums, moisturizers, toners, and lotions.

This preservation solution is particularly relevant for individuals who prefer to craft their own skincare without compromising on safety. It supports the use of ascorbic acid and hyaluronic acid powders, which are commonly incorporated into anti-aging and hydrating treatments. The three-pack format offers a cost-effective option for regular formulation work, reducing the need for frequent reordering. As a non-irritating, eco-conscious alternative to conventional preservatives, Leucidal SF COMPLETE helps extend the usable life of handmade products while maintaining their gentle profile. Users can integrate it into their existing recipes according to recommended usage rates, supporting consistent results across multiple batches.
