Cosmetics bottles are designed with various features to protect the product from air exposure, which can lead to oxidation and spoilage.

Here are some common methods used:

1. Air-tight Seals: Many cosmetic containers have airtight seals that prevent air from entering the bottle. This helps to keep the contents stable and prolongs shelf life.
2. Pumps and Dispensers: Airless pump bottles are designed to minimize air exposure. They use a vacuum mechanism to dispense the product without allowing air to enter the container.
3. Opaque Materials: Some cosmetics are packaged in opaque or dark-colored bottles to block light and reduce the risk of oxidation caused by UV exposure.
4. Foil or Seal Liners: Many bottles come with foil seals or liners that provide an additional barrier to air before the product is first used.
5. Minimalistic Design: Some designs minimize the opening size to reduce the amount of air that can enter when the product is dispensed.
6. Preservatives: While not a physical barrier, many cosmetics contain preservatives that help protect the product from degradation caused by air exposure.

These features collectively help maintain the integrity and effectiveness of cosmetic products.
