A girl can never have too many beauty products. Some have a dedicated place to keep all of them and for some, they take on the different territories of our livelihood like makeup bags, purses, night stands and TV cabinet. The place where you store your products may be shortening their shelf life and messing with their effectiveness. We asked our experts where one should and shouldn’t store their precious beauty products and this is what we found.

1. Protect them from Sun:

Sunlight accelerates the ageing of a product by heating it up, which can break down active ingredients. Countertops and vanities that are away from direct sunlight and extreme temperatures all day should be chosen to store. It’s best to store the majority of your products inside cabinets and drawers to keep them safe.

2. Refrigerator is the New Vanity

Cool temperatures can extend the shelf life of some products. For any skincare products with retinol or vitamin C, the cold temperatures will slow down the degradation of both ingredients. Speed up the de-puffing powers of your favourite eye cream and lower your skin temperature when applying after-sun products by keeping them chilly. And reshape lipsticks that melted in your purse or car, just be sure to take them out once they re-solidify—the chilliness can cause the oil and wax to separate over time.

3. Avoid the Bathroom Shelves

The steam from your shower is harmful to your products. Water can condense on the surface of certain cosmetics and start to generate mold. Move any bath salts and scrubs, powders, and anything that doesn’t have a really strong seal (like compacts and eye shadows) someplace dry. The same goes for any tools, like your makeup sponges, brushes that can become breeding grounds for mold if continually damp. After cleaning the tools, let them air dry outside of the bathroom.

4. Avoid Freezing Temps Too

Extremely cold temperatures can be just as harmful to your products as heat. Emulsions like lotions, creams, and conditioners, in particular, become very unstable if partially frozen and later thawed. If you live somewhere it’s freezing during the winter, remove them from any window sills.
