Nivea lip balm

Nivea lip balm is divided into three types: natural, repairing, men's, water balancing, and tinted. The most basic function of these lipsticks is to moisturize the lips and soothe dry and flaky lips without any toxic side effects. In addition, the Japanese version of Nivea lip balm comes in a variety of flavors such as peach and lemon. The formula is basically the same as the domestic version, except that the spices contained are different. The Japanese version of Nivea lip balm is also non-toxic and can be used daily.

Lipstick that has expired cannot be used

When certain chemical components in lipstick deteriorate, they will generate toxic substances that damage the lip mucosa. In severe cases, they can cause allergies, redness, swelling, and ulcers, and it will no longer have the effect of moisturizing and protecting the lips. In addition, lipstick often enters our stomach along with food when we eat. Spoiled lipstick can no longer guarantee the safety of its ingredients and may even produce toxic carcinogens. Eating it may cause food poisoning symptoms such as abdominal pain and diarrhea.

What happens if you use expired lipstick?

1. May be asymptomatic

Sometimes, even if you accidentally apply expired lipstick a few times, you don't have to worry too much. Especially for lipsticks that have just expired, although the lipstick has passed the shelf life guaranteed by the merchant, the ingredients of the lipstick may not have deteriorated, so no symptoms will occur after applying it. It is also possible that although the ingredients of lipstick have deteriorated, the lips have a certain self-defense ability, and the amount you apply has no effect on your lips.

2. Redness, swelling, and ulceration may occur

This situation is mainly because the ingredients of the lipstick have seriously deteriorated, and you have used this lipstick for a long time and in large doses, which has broken through the defense capabilities of the lip mucosa. If redness, swelling or ulceration occurs, stop using expired lipstick immediately, consult a doctor promptly, and take medication or other treatments if necessary.

3. You may have stomach pain

This is expired lipstick applied on the lips, which seeps into the stomach along with the food and causes gastrointestinal discomfort. It is recommended to seek medical advice in time and explain the specific situation to the doctor.
