Preservatives & Shelf Life

Yüm is an innovative collection that is constantly evolving and improving as discoveries in cosmetic chemistry occur. While our products contain a substantial amount of organic oils, butters, extracts and plant materials we are not organic certified. We made the decision not to offer certified products because we want to use cutting edge, powerful skin conditioners which help your skin retain balance and vitality. To keep our products as fresh as possible, we run frequent small batches which are hand filled and packaged for you. We have developed a proprietary preservative system that is robust yet paraben-free. 

Due to our very fresh content and ingredients, our products require special handling. Many Yüm formulations contain photo-sensitive ingredients that can be adversely affected by direct sunlight. To retain the efficacy of many of our ingredients, we sell all specialty treatment products in recyclable boxes. We also recommend the use of spatulas when handling crèmes and masques to minimize contamination. A unique feature of Yüm products is their seasonal variation in the appearance which can change with the time of year and times of harvest for many of our raw materials. As with all natural products, we recommend you keep them fresh by storing in a cool dark place with stable and consistent room temperature. Never expose Yüm products to extreme heat or cold as it will compromise the emulsion and shelf life of the product. Typical room temperature is 68-77 degree F (20-25 degrees C) and is the ideal environment for Yüm. When cosmetics of any kind are stored at higher temperatures, the preservative system is significantly deteriorated. A good rule of thumb is that; one week stored at temperatures higher than 85 degrees F is equal to three months shelf life.
