Can I store vitamin C serum in a plastic bottle?

Are you using a vitamin C serum and wondering about the best way to store it? Vitamin C is a powerful ingredient. But it is also very delicate. The type of bottle you use can greatly affect how long your serum stays effective.

Storing vitamin C serum in a plastic bottle is generally not ideal, especially if the bottle is clear or highly permeable to air. Vitamin C is highly sensitive to light and air (oxidation), which can degrade its potency quickly. To maintain its effectiveness, vitamin C serum is best stored in opaque, airless, or dark glass bottles that limit exposure to light and oxygen, protecting the active ingredients.

When I consult on packaging, I always highlight the importance of material choice for sensitive formulas. A well-chosen bottle can preserve a product's integrity. A poor choice can quickly render an expensive serum useless.

Sensitivity of Vitamin C

Vitamin C (L-ascorbic acid) is a very unstable ingredient.

• Oxidation: Exposure to air causes vitamin C to oxidize. It turns yellow or brown, and loses its effectiveness.
• Light Sensitivity: UV light can also break down vitamin C molecules. This speeds up degradation.
• Heat Sensitivity: High temperatures can also harm vitamin C.

Plastic Bottle Concerns

Many plastic bottles do not offer enough protection.

• Air Permeability: Some plastics, especially thinner ones, allow small amounts of air to pass through. This causes oxidation.
• Light Transmission: Clear plastic bottles let light reach the serum. This accelerates degradation.
• Chemical Interactions: While less common with stable plastics, some plasticizers could potentially interact with delicate formulas.

Ideal Storage Conditions

To protect vitamin C serum, specific packaging is needed.

• Opaque Packaging: Bottles should be dark or opaque. This blocks light from reaching the serum.
• Airless Pumps: Airless pump bottles are excellent. They prevent air from entering the container. This stops oxidation.
• Dark Glass Bottles: Amber or cobalt blue glass can block some light. But it still allows air if not an airless pump.
• Cool, Dark Place: Always store the bottle in a cool, dark place. This reduces heat and light exposure.

What is the best way to store skincare?

Are you investing in good skincare products and want to make them last? Proper storage is just as important as the product itself. The right storage can help maintain product potency and extend its shelf life.

The best way to store skincare is in a cool, dark place, away from direct sunlight, extreme temperatures, and excessive humidity. Products with sensitive ingredients, like vitamin C or retinol, benefit greatly from airless pump bottles or opaque containers to minimize exposure to light and air, preventing degradation and maintaining their effectiveness over time.

I often tell my clients that even the best formulations can be compromised by poor storage. Packaging design plays a big part in protecting products. However, consumers also have a role in how they keep their skincare at home.

General Storage Rules

These apply to most skincare products.

• Cool and Dark: Store products in a cupboard or drawer. Avoid windowsills or sunny countertops.
• Away from Heat: Keep them away from radiators, hot lights, or direct sunlight. Heat can break down ingredients.
• Avoid Humidity: Do not store products in steamy bathrooms. Humidity can promote bacterial growth in some formulas.
• Tight Lids: Always ensure lids are tightly closed after use. This prevents air entry and contamination.

Specific Product Needs

Some ingredients need extra care.
