What precautions should consumers take when handling mascara cases?

To ensure proper product use, extend the product's lifespan, and protect eye health, consumers should observe the following:

Opening and Closing

Opening: When opening the mascara case for the first time or each time, be gentle. Avoid applying excessive force, which can cause the mascara to spill, resulting in waste and potentially contaminating the case. Slowly unscrew the lid to allow air to enter and balance the pressure inside and outside.

Closing: After use, tighten the lid promptly and tightly. If the lid is not tightened, dust and bacteria from the air can easily enter the mascara, causing it to deteriorate and dry out, potentially affecting subsequent use.

Usage Instructions
Using the Brush: When removing the mascara brush from the case, gently scrape off any excess mascara from the tube to prevent it from accumulating too much, which can cause clumping and clumps during application. When applying, gently move the brush in a "Z" motion from the base of the lashes to the tip, evenly coating each lash.

Avoid contamination: During use, avoid touching the brush head to other objects to prevent contaminants such as dust and bacteria. Also, avoid repeatedly dipping the brush head back into the mascara. If the mascara becomes contaminated, it can cause an eye infection. If you accidentally dip too much, wipe off the excess on the tube instead of putting it back in and taking more.

Shelf Life: Pay attention to the mascara's shelf life. Generally, it's recommended to use it within 3-6 months after opening. Beyond the expiration date, the mascara can easily harbor bacteria. Even if the appearance remains unchanged, do not continue to use it to avoid eye irritation or infection.

Storage Environment
Temperature and Humidity: Store the mascara case in a cool, dry place, away from direct sunlight and high temperatures and humidity. High temperatures can cause the mascara to melt and deteriorate, affecting its effectiveness. Humidity can easily cause the mascara to become damp and breed bacteria.

Avoid squeezing: Store the mascara case away from squeezing or impact to prevent deformation, compromised sealing, and even leakage.

Cleaning and Maintenance
External Cleaning: If the mascara case becomes stained, gently wipe it with a clean, soft cloth. Avoid using detergents containing chemical solvents, as these may corrode the surface.

Internal Cleaning: Over time, some mascara residue may remain on the inside of the case. Periodically, gently wipe the inside with a clean cotton swab, but be careful not to let any fibers from the swab get into the mascara. If the mascara develops an odor, changes color, or changes in texture, discontinue use immediately.
