While storing certain skincare products in the refrigerator can help prolong their shelf life or improve their application, there are certain products that should generally not be refrigerated:
- Oils and Oil-based Serums: Cold temperatures can cause these products to solidify or become cloudy. While it doesn’t necessarily harm the product, it can change its texture and make it more difficult to use.
- Retinoids: Most retinoid formulations are best stored at room temperature, as refrigeration may cause the active ingredients to separate or destabilize.
- Clay Masks: Refrigeration can cause clay masks to harden, making them difficult to apply.
- Creams and Lotions with Thick Consistency: Some thick creams and lotions may become too hard in cold temperatures and might not spread easily on the skin.
- Wax-Based Products: Products like lip balms or wax-based salves can become extremely hard and difficult to apply when stored in the fridge.
- Makeup: Most makeup, like foundations, mascaras, and lipsticks, are formulated to be stable at room temperature. Refrigeration may alter their texture and application.
- Fragrances: Perfumes and fragrances should be stored in cool, dark places, but refrigeration can sometimes alter the scent.
- Probiotic Skincare: While it may seem counterintuitive, some probiotic skincare products have strains that can become inactive if stored at too low a temperature.
- Certain Acne Treatments: Some acne treatments, especially those containing benzoyl peroxide, can crystallize and lose efficacy when refrigerated.
- Nail Polishes: Refrigeration can cause the formula to thicken and separate.
It’s always a good idea to read the product’s label and storage instructions, as some products may have specific recommendations regarding storage. If there’s ever any doubt, consulting with the manufacturer or a skincare professional can be helpful.
