Storage of Timed-Released BHA Toner

Dear Customer,

Regarding your question about the storage instructions for Timed-Released BHA Toner (+b3 5% +n-acetyl D 4%), here is an explanation:

The information on the website states that the product has a shelf life of at least 1 year and should be kept away from sunlight and heat. This is general advice for storing most cosmetic products to maintain their quality according to minimum standards.

The recommendation on the product label to store it in the refrigerator at 4-8°C is for optimal preservation of the active ingredients, ensuring they maintain their maximum efficacy for the longest possible time. Some ingredients can degrade more easily at higher temperatures.

As advised by cosmeceutical7, refrigeration is the best storage method for almost all cosmetic products. However, storing at room temperature is not necessarily bad, as long as the product is not placed in direct sunlight or in a very hot room.

If you cannot store the product in the refrigerator, keeping it at normal room temperature in a dry, cool place away from direct sunlight and heat will help slow down degradation. However, the shelf life or the period during which the product maintains its peak efficacy might be shorter compared to refrigerated storage. Generally, if stored in suitable conditions (not excessively hot, not exposed to sun), the product should still perform well within the 1-year period mentioned on the website.

It is important to observe the product's condition. If you notice significant changes in texture, color, or smell, or feel that the efficacy has significantly decreased, it might be time to stop using it.

In summary, while refrigeration is best, storing at a suitable room temperature (away from sunlight and heat) can still maintain the product's quality within the 1-year shelf life.
