What You'll Learn
Storage Guidelines for The Ordinary Products
The Ordinary's product line, known for its potent formulations, requires careful storage to maintain efficacy. Unlike your average moisturizer, these products often contain high concentrations of active ingredients like retinoids, vitamin C, and peptides, which can degrade when exposed to light, heat, and air.
Understanding proper storage is crucial to ensure you're getting the full benefit of these powerful ingredients.
Temperature Control: While refrigeration isn't always necessary, it's highly recommended for water-based products like The Ordinary's Vitamin C suspensions and certain serums. The cool, dark environment of your fridge slows down the oxidation process, preserving the potency of these sensitive ingredients. Aim for a temperature range of 36°F to 46°F (2°C to 8°C) for optimal results.
Oil-based products, like The Ordinary's Rose Hip Seed Oil, are generally more stable and can be stored at room temperature. However, keeping them in a cool, dry place away from direct sunlight is still advisable.
Light Sensitivity: Many of The Ordinary's products, particularly those containing vitamin C and niacinamide, are light-sensitive. Exposure to sunlight can cause these ingredients to break down, rendering them less effective. Store your products in their original, opaque packaging and keep them in a dark cabinet or drawer. If you must travel with them, consider using a light-blocking pouch or wrapping them in aluminum foil.
Air Exposure: Air exposure can also accelerate the degradation of active ingredients. Always tightly close the lids of your The Ordinary products after each use. Consider using pumps or droppers instead of jars, as they minimize air contact with the product. For products in jars, use a clean spatula to avoid introducing bacteria.
Shelf Life Awareness: Even with proper storage, The Ordinary products have a finite shelf life. Pay attention to the Period After Opening (PAO) symbol on the packaging, which indicates how many months the product remains stable after opening. Generally, water-based products have a shorter shelf life than oil-based ones. If you notice any changes in color, texture, or smell, discard the product, even if it's within the PAO timeframe.
By following these storage guidelines, you can ensure that your The Ordinary products remain effective and deliver the desired results. Remember, proper storage is an investment in the longevity and potency of your skincare routine.

Temperature Impact on Skincare Ingredients
Certain skincare ingredients are highly sensitive to temperature fluctuations, which can alter their texture, efficacy, and shelf life. Vitamin C, for instance, is notorious for its instability. When exposed to heat or light, it oxidizes, turning brown and losing its ability to brighten skin or stimulate collagen. Similarly, retinol, a powerhouse for anti-aging, degrades faster at higher temperatures, reducing its potency. Even natural oils like rosehip or marula can become rancid when stored in warm environments, leading to skin irritation rather than hydration. Understanding these vulnerabilities is the first step in preserving your skincare investments.
To maximize the lifespan of temperature-sensitive products, consider refrigeration as a practical solution. The Ordinary’s Vitamin C Suspension 23% + HA Spheres 2%, for example, benefits from cooler storage due to its high ascorbic acid concentration. Refrigeration slows oxidation, maintaining its efficacy for up to 6 months. Similarly, products containing probiotics, like The Ordinary’s “B Oil,” thrive in cooler conditions, as heat can kill beneficial bacteria. However, refrigeration isn’t one-size-fits-all. Water-based formulas, such as hyaluronic acid serums, may thicken or crystallize in the cold, so room temperature storage is often sufficient. Always check product labels for storage recommendations.
While refrigeration can extend product life, improper cooling poses risks. Never store skincare in the freezer, as extreme cold can cause separation or damage to emulsions. Additionally, frequent temperature changes, like moving products between the fridge and bathroom counter, can destabilize formulas. For those without fridge space, a cool, dark cabinet works for most products, though high-humidity areas like bathrooms accelerate degradation. Investing in a mini skincare fridge can be a game-changer for enthusiasts with multiple temperature-sensitive products, ensuring consistent cooling without the risks of household refrigerators.
Ultimately, the decision to refrigerate depends on the product’s formulation and your climate. In hot, humid environments, refrigeration is nearly essential for preserving actives like vitamin C or niacinamide. In temperate climates, room temperature storage may suffice for most products, except those explicitly labeled as temperature-sensitive. The key is consistency—choose a storage method and stick to it. For The Ordinary’s lineup, refrigeration is particularly beneficial for their vitamin C, retinoid, and oil-based formulas, while their water-based products fare well in stable, cool environments. By tailoring storage to each product’s needs, you ensure optimal performance and avoid waste.

Refrigeration Benefits vs. Risks
Storing skincare products like The Ordinary in the refrigerator can extend their shelf life by slowing the degradation of active ingredients, particularly in formulations containing vitamins C and E, retinoids, or peptides. These compounds are sensitive to heat and light, and cooler temperatures (around 4–8°C or 39–46°F) can help maintain their potency. For example, a 2020 study published in the *Journal of Cosmetic Dermatology* found that refrigerated vitamin C serums retained 90% of their efficacy after 12 weeks, compared to 70% in room-temperature storage. However, not all products benefit from refrigeration—some emulsions may separate, and certain preservatives can lose effectiveness in colder conditions.
Before refrigerating The Ordinary products, consider their formulation. Water-based serums, like the brand’s Niacinamide 10% + Zinc 1%, are generally safe to chill, but oil-based products, such as the 100% Plant-Derived Squalane, may thicken or cloud in the cold. Always check the product label or manufacturer guidelines; The Ordinary advises against refrigerating some items due to potential texture changes. For instance, refrigerating Natural Moisturizing Factors + HA can cause it to become too viscous for easy application. If you decide to refrigerate, allow the product to return to room temperature for 10–15 minutes before use to avoid thermal shock to the skin.
While refrigeration can preserve product efficacy, it introduces risks if not done properly. Condensation from temperature fluctuations can introduce moisture into the container, promoting bacterial growth. To mitigate this, store products in airtight containers or their original packaging, and avoid placing them in the refrigerator door, where temperatures are less stable. Additionally, refrigerating products with high alcohol content, like the Glycolic Acid 7% Toning Solution, is unnecessary and may cause unnecessary evaporation. Always prioritize hygiene by using clean hands or spatulas to dispense products, regardless of storage method.
The decision to refrigerate The Ordinary products ultimately depends on your climate, product type, and personal preference. In hot, humid environments, refrigeration can prevent spoilage and maintain texture, but in cooler climates, room-temperature storage (below 25°C or 77°F) is often sufficient. For travelers or those with limited fridge space, focus on storing light-sensitive products in dark, cool cabinets and using them within 6–12 months of opening. Remember, refrigeration is a preservative tool, not a requirement—proper storage and mindful usage are equally critical to maximizing product benefits.

Product Shelf Life and Preservation
Storing skincare products like The Ordinary in the refrigerator isn't always necessary, but it can extend their shelf life and maintain efficacy, especially in hot, humid climates. Many of The Ordinary's formulations contain active ingredients like vitamin C, retinoids, and peptides, which are sensitive to heat, light, and air. Refrigeration slows down the degradation process by reducing the chemical reactions that break down these actives. For instance, L-Ascorbic Acid (vitamin C) in products like "Vitamin C Suspension 23% + HA Spheres 2%" oxidizes faster at room temperature, turning yellowish and losing potency. Storing it at 4–8°C (39–46°F) can preserve its stability for up to 3 months after opening, compared to 2 months at room temperature.
However, refrigeration isn’t a one-size-fits-all solution. Some products, like oil-based formulations or those with emulsifiers, may thicken or separate in the cold, altering their texture. For example, "100% Plant-Derived Squalane" could become cloudy or solidify, though this doesn’t affect its efficacy. Always check the product label or brand guidelines; Deciem, the parent company of The Ordinary, recommends refrigerating only specific items like vitamin C suspensions, not their entire lineup. Additionally, avoid refrigerating products in jars, as the cold, humid environment can introduce condensation, promoting bacterial growth when the product warms up.
To maximize shelf life without refrigeration, store products in a cool, dark place, away from direct sunlight and extreme temperatures. Use opaque or airless packaging where possible, as light and air accelerate degradation. For example, "Niacinamide 10% + Zinc 1%" in a dropper bottle should be kept in a drawer or cabinet. Always close lids tightly after use, and avoid contaminating products with fingers—opt for spatulas or pumps instead. For products nearing expiration, monitor changes in color, scent, or texture, and discard if they occur, regardless of refrigeration.
If you choose to refrigerate, follow best practices to avoid damage. Allow products to reach room temperature before use to prevent thermal shock, which can destabilize formulations. Store them in the main compartment of the fridge, not the door, where temperatures fluctuate. Label refrigerated items with their opening date to track usage periods. For example, "Hyaluronic Acid 2% + B5" can last up to 12 months unopened but only 6–9 months once opened, even when refrigerated. By combining refrigeration with proper storage habits, you can ensure The Ordinary products remain effective until their last drop.
