What are the storage recommendations for this cosmetic oil to maintain its quality?

To keep the hazelnut cosmetic oil at its best, follow these simple storage guidelines:

• Temperature: Keep the bottle between 15 °C and 25 °C (59 °F–77 °F). Avoid extreme heat or freezing, which can alter the oil’s texture.
• Light: Store in a dark or opaque container and place it in a cupboard or drawer that is not exposed to direct sunlight. Light can accelerate oxidation.
• Air exposure: Seal the cap tightly after each use. The oil is a single‑ingredient product, so minimal air contact helps prevent rancidity.
• Shelf life: The product does not contain preservatives, so it is best used within 12 months from the date of opening. Check the bottle for any off‑smell or change in color before use.
• Handling: Use clean hands or a clean dropper to avoid introducing contaminants that could shorten the oil’s usable life.

Following these practices will help maintain the oil’s smooth texture and natural feel throughout its shelf life.
