Packaging and Storage: How Can You Store Your Products Properly So They Last Longer?

You’ve spent money on quality products—but are you preserving their effectiveness by storing them properly? Light, heat, and air are silent enemies that quickly spoil products without you even noticing. Proper storage extends the shelf life of your products and preserves their effectiveness.

Vitamin C (pure ascorbic acid): Very sensitive to heat and light—it oxidizes and turns orange. Refrigeration significantly extends its shelf life. Retinol and retinoids: They break down when exposed to light—store them in the refrigerator or in a cool, dark place. Probiotics in skincare products: They need to be kept cool to maintain live bacteria. Vitamins in aqueous formulations in general: They are negatively affected by high heat.

Keep away from the bathroom! — Steam and constant humidity ruin the products. The bathroom is fine for makeup but terrible for skincare products. Direct light: Move them to a drawer or a closed cabinet. Ideal temperature: 15–25 degrees — keep away from windows and the heater. Close the lid tightly after each use — air oxidizes the ingredients.

Color change: Vitamin C turns yellow; white creams turn yellow or gray. Odor change: A sharp or unpleasant odor that wasn’t there before. Texture change: The layers of an emulsion separate, or a serum becomes watery. Change in texture: A product that used to be smooth becomes clumpy or rough. When in doubt: Don’t risk your skin—throw it away. Check the PAO (Period After Opening)—the code printed on the product packaging indicating the number of months.
