Mentholatum's lip balm is Mentholatum's main product, with excellent reputation and sales. However, a product must have a shelf life. So, can Mentholatum lip balm still be used after it expires?

Can I still use Mentholatum lip balm if it is expired?

cannot. Do not use expired lip balm. The substances in expired lip balm will change and produce some toxic substances, which will have a negative effect on the skin of the lips. Moreover, the lips are relatively delicate and sensitive, and are prone to allergic reactions.

How long is the shelf life of Mentholatum lip balm

5 years. This refers to the unopened state. After opening, the shelf life is only six months to one year. Most lip balms have a shelf life of 3 years before opening, and only a few brands have a shelf life of 4 or 5 years. For example, Mentholatum's lip balm has a shelf life of 5 years before opening. But once opened, it must be used up within six months to a year.

How to tell if lip balm is expired

1. Look at the color

The simplest way to judge is to see whether there are mildew spots on the paste. Some lipsticks contain more protein. In spring and autumn, the suitable temperature and humidity conditions can easily allow fungi and bacteria to grow, causing the lipstick to become moldy.

2. Smell

You should be very familiar with the smell of the lip balm you have used. If you find that the smell has become different from before, it means that it has gone bad, because the lipstick will be oxidized when exposed to air after being opened.

3. Look at the moisture

Expired lip balm looks very dry. When applied on the lips, you will not feel any moisturizing effect. Instead, your lips will feel drier, as if covered with a layer of dust. This shows that the quality of the lipstick has changed. The expired lipstick also contains less moisture and has no moisturizing effect.

4. Look at the paste

You can check the condition of the lipstick with your naked eyes. The deteriorated lipstick will look very dry and hard, and will break easily if you press it lightly with your hands. Because it is fragile, if this is the case, don't use it anymore.
