Taking care of your oil-based beauty products is essential if you want them to last and perform their best. With many serums and oils coming at a premium price, knowing how to store and handle them properly helps protect your investment and keeps your skincare routine effective.
Understanding oil degradation
Oils can go rancid through a process called oxidation, where they react with oxygen in the air. This process is accelerated by heat, light, and exposure to contaminants. Rancid oils not only smell unpleasant but can also lose their beneficial properties and potentially irritate the skin.
Even with the best care, oil-based products will eventually expire. Key signs of oil degradation include a change in smell, color or texture. If your product shows any of these signs, it's best to toss it.
But with a little TLC, you CAN keep your oil-based cosmetics fresh and effective for longer. ☺️ Proper storage, hygiene, and knowing the signs of rancidity are key.
Tips for extending shelf life
- Minimize air exposure: Tightly close lids immediately after use to prevent air and moisture from entering the container.
- Storage + temperature control: Keep products in a cool, dark place away from direct sunlight. Avoid storing products in areas with high humidity or fluctuating temperatures, such as bathrooms. Consistent, cool temperatures are ideal.
- Use clean hands: Always use clean hands or applicators to avoid introducing bacteria and other contaminants into the product.
