When we ship our products, we do understand that there's a risk the package will be exposed to extreme temperatures on certain occasions. You can rest assured that this type of short-term exposure does not compromise the effectiveness of our products. All Paula's Choice products are stability-tested and capable of withstanding these conditions. Due to our packaging, products left in direct sunlight are completely safe and will not degrade. Products which have frozen are perfectly fine to use as well, after you let them thaw to room temperature. Please do not use any other methods to restore the product to room temperature, such as heating the product in the microwave or cooling it down in the refrigerator.
Please know that the information above refers to one-time instances, such as the product becoming frozen or very hot while in transit from our warehouse to your home. We do not recommend letting your products become frozen or very hot on a regular basis throughout the life of the product, such as what might occur if you were to store them in your car long-term during winter or summer.
Please keep in mind that if you are not satisfied with our products for any reason, we offer a return policy, which you can read more about here.
