GUIDELINES FOR PROPER USAGE AND MAINTENANCE OF PRODUCTS

As we use only the finest natural ingredients known to us and minimal preservatives in our fresh, original preparations, we offer the following guidelines to help maintain the freshness and efficacy of Kiehl's formulations for as long as possible:

Suggested Usage Schedule

We recommend that face creams be used within three months of purchase; body creams and hair conditioners should be used within six months of purchase. Cleansing products, including shampoos and body cleansers, generally have a shelf-life of one year or more from date of purchase. In general, it is a good idea to refrigerate products to extend their lifespan.

Climate Control

Products should not be exposed to extreme heat, cold, or temperature changes and should be kept out of direct sunlight. Products should be kept in a cool, dry place. Bathrooms are not usually ideal locations for product storage, because the temperature and humidity levels there change frequently.

Usage

We recommend use of sterile disposable, plastic spatulas or swabs with all creams packaged in jars - rather than fingers - to remove the product form the jar in order to decrease the potential introduction of bacteria from the fingertips into the product.

Post-Usage

Please be sure to close lids tightly on all jars and to remove any residue from the spouts on bottles before each use. Bottle tops should be fully closed when storing product or between applications.

A Note on Product Variation

Because Kiehl's utilizes natural ingredients in our unique formulations, our products may vary in color and consistency with each new batch that we make. These natural variations do not in any way affect the quality or efficacy of the product.

We want you to enjoy and benefit to the utmost from your Kiehl's products. If you should ever have any questions about Kiehl's product or their use, please do not hesitate to call on us at any time. It is always our great pleasure and honor to serve you however we can.


What is the lifespan of Kiehl's products?

Generally, a sealed product has a lifespan of 3 years in normal room temperature (without exposure to heat, cold and light). This is a result of Stability test performed in a lab. This test is carried out with manufacturing samples that were random from both finished goods and bulk with the following steps.

- Accelerated Laboratories Studies is carried out by acceleration of oxidation to find out chemical and physical reaction of the product. In the accelerated environment, samples are collected from accelerated environment in order to find out the factors that predict the lifespan of a product. In practice, the test is carried out in one temperature environment at 45°C, 75% humidity and samples are collected at 0, 1, 2, 3 and 4 months. If the quality of the product meets the standard on the 4th month, it is possible to temporarily determine the lifespan. Laboratory test in 3 or 4 varied temperatures is also acceptable for collecting samples for chemical and physical test, most results yielded 3 year or more of lifespan therefore the credible lifespan is 3 years.

- Long Term Studies is a test that is designed to reassure the quality of products during shelf life. The samples are collected in the environment as identified on the label at 3, 6, 9, 12, 18 and 24 months and yearly for 3 years.

There are factors of humidity and contamination after opening the products, therefore microscopic tests are required at different conditions depending on type and quantity of preservatives. Generally preservatives in skin care preserve the products for no longer than 1 year after opening.
