The efficacy of La Mer lipstick

La Mer lipstick contains concentrated plant extracts that can immediately soften rough lips, relieve uncomfortable feelings, and repair seasonally dry lip skin as soon as it is applied to the lips. When it comes to protecting against rough lips caused by temperature differences, strong winds, dry environments and changes in eating habits, La Mer lipstick is more targeted. In addition, it can strengthen the skin barrier. Use it once at night to continuously moisturize during the day and maintain humidity indoors.

How long is the shelf life of La Mer lipstick

The shelf life of La Mer lip balm is 12 months, and if it is unopened, the shelf life is generally 3 years. Once opened, it is best to use up La Mer lip balm within 12 months. Repeated use over a long period of time will allow some microorganisms to enter the lip balm, affecting the ingredients of the La Mer lip balm, making it unable to provide lip protection and may also cause lip allergies.
