Off-the-shelf commercial products require a shelf life of 36+ months. Although Calli Essentials products contain a full spectrum preservative, it is less than 1% and eco-certified (classified as ecologically friendly raw material based on EU regulations and accepted by Whole Foods). Our shelf life is less because our products are nutrient-dense with high quality, pure and natural carrier oils, hydrosols and botanical extracts. Additionally, there is a high concentration of these quality ingredients in all our products, unlike off-the-shelf products which contain trace amounts of botanical extracts and are made up largely of water and synthetic ingredients.

Our skin is in a constant state of renewal. How long it takes to produce new skin cells depends on age, health and diet - on average we can assume 4-8 weeks. If we feed our skin with quality ingredients that help balance the skin, encourage cell growth, strengthen existing cells & protect the skin and couple that with a healthy lifestyle, aggressive treatments are not really necessary. Remember you are working on promoting the growth of new and healthy cells so it is very important that with any skincare product you use, you must allow 4-8 weeks to see the overall effects.

It is important to note that there is no official rating agency for determining 'therapeutic grade' but the term is used to describe oils that are unadulterated, 100% natural, extracted through proper methods (such as steam or water distillation) and produced in small batches. They are free of chemicals and pesticides. Oils used by the pharmaceutical industry (which are the oils most often used in over-the-counter products, perfumes etc.) are often diluted or adulterated and are extracted by methods that do not protect the therapeutic constituents of the plant and therefore have little (if any) therapeutic properties.

Because essential oils and carrier oils are grown in different regions around the world we are dealing with changing weather and soil conditions, giving the essential and carrier oils slightly different characteristics. Like fine wines, they can vary from year to year or batch to batch.
