50ml Lotion Bottle Cosmetic Jar Screw Cap Custom Color Pp/pcr Double Airless

Completely airtight: The product remains completely isolated from oxygen from filling to use, making it the most airtight packaging solution on the market.

Prevents oxidation and spoilage: Easily oxidized ingredients such as Vitamin C, Vitamin E, Coenzyme Q10, and Retinol maintain their activity.

No need for large amounts of preservatives: Because bacteria cannot multiply in an anaerobic environment, "additive-free" and "pure skincare" formulas become possible.

Extended shelf life after opening: The usage period after opening is several times longer than ordinary wide-mouth bottles.

Prevents product drying out: Lotions and foundations will not thicken due to water evaporation.

Maintains pure fragrance: The scent of essential oils and fragrance products does not evaporate or dissipate.

Isolates from external bacteria: Air and fingers do not come into contact with the remaining product during use, avoiding secondary contamination.

Light protection: Combined with opaque or dark-colored bottles, it provides double protection for photosensitive ingredients.
