Storage of Sensitive Cosmetic Ingredients Without Refrigeration
Question
I have sensitive cosmetic ingredients like peptides and hyaluronic acid that require refrigeration. How should I store them if I don't have access to refrigeration? Is using a box with ice and salt a suitable method? What is the impact on the ingredients' effectiveness if they are stored at room temperature?

Subject: Ingredient Storage Without Refrigeration
Hello,
Thank you for your question regarding storing ingredients like peptides and hyaluronic acid without refrigeration. This is a common challenge when dealing with sensitive raw materials.
As the staff member explained, ingredients don't degrade instantly, but their potency decreases over time. Refrigeration is recommended because it significantly slows down this natural degradation process, helping the ingredients maintain their effectiveness for longer (extending the shelf life).
Storing ingredients that require refrigeration at room temperature will accelerate their degradation. While they may still be usable for a period, their efficacy will decline faster than if stored correctly in a refrigerator.
Regarding your idea of using ice and salt in a box, while this can provide temporary cooling, it is generally not a recommended method for storing sensitive cosmetic ingredients long-term. It's difficult to maintain a consistent temperature, and moisture from melting ice could potentially affect the ingredients.
Based on the situation and the staff's advice, the most practical solution is to:
- Purchase the smallest possible quantities of ingredients.
- Plan to use them up relatively quickly after opening.
By buying small amounts and using them promptly, you minimize the time the ingredients are exposed to room temperature, thus reducing the extent of degradation before you use them.
We hope this helps!
