What Skincare Products Should Not Be Refrigerated?

Adding a skincare fridge to your beauty routine has become a popular trend in recent years. Certain compounds, such as retinol and vitamin C, have their shelf life and efficacy extended by the low temperature.

Still, not every skincare product works better refrigerated. Some may even lose their effectiveness or break down more quickly in the cold. It’s Important to Know what Skincare Products Should not be refrigerated in addition to Knowing What to Add. 

Why Refrigerate Skincare at All?

The usage of skincare refrigerators increases the stability and efficacy of temperature-sensitive ingredients. Certain components, such peptides and antioxidants, can degrade more quickly when exposed to heat, light, and air. Keeping them cold stops this early disintegration. Additionally, refrigeration inhibits the development of microorganisms that might taint your goods.

Most skincare products work best at a temperature of 4 to 8°C. This cool but not freezing temperature extends the life and potency of ingredients. It imitates the settings in which clinical trials and product development take place. Therefore, chilling allows you to experience the full range of benefits that the formulations were designed to provide.

Naturally, not all skincare products require refrigeration. It’s true that certain combinations and ingredients break down more quickly in the winter. It is essential to know which ones to keep out of the refrigerator in order to preserve their efficacy. 

What Not to Put in a Skincare Fridge?

What Skincare Products Should not Be Refrigerated

1. Oils and Products Made from Oil

Plant oils and oil-based cosmetics and balms can solidify and cloud in the refrigerator. The oils change viscosity and texture as a result of congealing and hardening in the cold. 

When reheated to room temperature, they usually return to their former condition. However, over time, warming and chilling oils repeatedly might hasten their deterioration.

2.  Items in Pump Bottles

Cold temperatures have the potential to influence the mechanics of pump bottles. It’s possible for the pump to stiffen up and become challenging to use. When cold, the product may potentially become too viscous to pump effectively. Pump-style products, like as cleansers and moisturizers, should be kept out of the refrigerator.

3. Silicone Products

Primer and mask made of silicone are also extremely sensitive to temperature. They get rubbery and thicken in the cold. The performance and user experience of the product may suffer as a result. For optimal results, let silicone formulations come to room temperature before using.

4. Masks of Sheet

While refreshing, keeping sheet masks in the refrigerator might cause them to dry out. Masks become stiffer and less saturated as a result of the cold air removing moisture from the cloth. When not in use, store sheet masks in a sealed container at room temperature for optimal outcomes.

5. Aluminum Containers

Refrigerating skincare products in metal tubes or containers is not recommended. Tube crimped seals may break as a result of metal contracting and warping in the cold. This jeopardizes the product’s containment and sterility. Over time, it also causes the oxidation through the damaged seals to grow.

6. Unsealed Products

Any skincare products not packaged in air-tight containers shouldn’t go in the fridge. Examples include jars with screwed lids or tubs with peel-off covers. The cold, dry air of refrigerators can evaporate the water content and stale exposed product. Tightly sealed pumps, squeeze tubes and bottles maintain freshness best.

7. Water-Based Products

Gels, serums and emulsions containing a high-water content tend to freeze or crystallize in the fridge. This gives them an altered texture that can impact application and absorption. Unless instructed to refrigerate, watery products are best kept at room temperature.

What to Put in a Skincare Fridge?

Now that you know What Skincare Products Should Not Be Refrigerated, let’s examine the skincare products that work best when refrigerated:

1. Retinol and Retinoids

In heat and light, retinol and prescription retinoids, such as tretinoin, become extremely unstable. Their potency can last up to a year when refrigerated, often lasting three months. Because of this, storing these vitamin A derivatives in the refrigerator is the best option.

2. Vitamin C 

Similar to retinol, vitamin C degrades quickly in the presence of air, light, and high temperatures. Liquid vitamin C serums and emulsions kept in the refrigerator maintain the antioxidant’s efficacy.

3. Various Flower Oils and Extracts 

In a refrigerator, the delicate essential oils and plant extracts such as lavender, chamomile, and rose stay fresher longer. This keeps their aromatherapeutic qualities intact.

4. Acids

Refrigerating alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) prolongs their efficacy as exfoliants. Applying chilled formulations to the skin also feels more revitalizing.

5. Peptides

Peptides, which are combinations of amino acids, have anti-aging properties. However, they frequently have high heat and light sensitivity. Refrigeration extends the stability and useful life of topical peptide compositions.

6. Prebiotics

For maximum survival, live probiotic extracts and bacteria need cold temperatures. Refrigerating dermatological probiotic skincare products helps them maintain more active microorganisms.

7. Sunscreen

The efficacy and integrity of sunscreen components compromises, if stored at high temperatures. Refrigeration in between applications maintains antioxidant and UV-blocking properties.

How Cold Should Your Skincare Fridge Be?

The ideal temperature range for your skincare refrigerator is 4° to 8°C. This is in line with the typical temperature of the majority of domestic food freezers. You may check the temperature inside your refrigerator by using a thermometer. The most dependably chilly shelves are usually those in the center.

Keep your skincare refrigerator away from very cold conditions, such as below freezing 0°C. It may harm certain formulations. Furthermore, avoid keeping it warmer than a food refrigerator since this might lessen the stabilizing effects. By modifying the unit’s temperature setting, the ideal 4°–8°C temperature range for skincare may be more effectively managed.

Should Skincare Be Refrigerated All the Time?

The biggest way to extend the life of your items is to refrigerate them continuously. Still, it’s not always feasible to keep everything in the refrigerator. 

You should refrigerate majority of skincare products until you’re ready to use them. Before using, take the product out of the refrigerator and let it reach room temperature. Applying ice directly to the skin might cause discomfort and hinder the absorption process.

The best results come from regularly refrigerating serums and moisturizers that include heat-sensitive components like vitamin C and retinol in between usage. However, even non-fridge items will survive longer if stored in dark, cold locations like drawers while not in use.

How Long Does Skincare Last in the Fridge?

Skincare items can last much longer in the refrigerator than the manufacturer’s stated expiration date. The following broad recommendations will help you extend the shelf life of essential ingredients:

  • Vitamin C: 9-12 months refrigerated vs. 2-3 months unrefrigerated.
  • Retinol: Up to 2 years refrigerated vs. 3-6 months unrefrigerated.
  • AHAs/BHAs: 2+ years refrigerated vs. 1 year unrefrigerated.
  • Natural Oils: 1-2 years refrigerated vs. 6-12 months unrefrigerated.
  • Sunscreens: Up to 1 year refrigerated vs. 6-9 months unrefrigerated.

Naturally, no refrigerator can completely prevent product deterioration. Nonetheless, regular cold storage ensures that you get the most out of your skincare expenditure.

Be alert for changes in the way that refrigerated products work, feel, and smell. It might be expired even after being refrigerated if it appears less effective or spreads unevenly. Replace complex serums and actives within the manufacturer’s recommended time frame if in doubt.
