What happens if you apply expired lipstick? How to tell if the lip balm is expired?

Lips need a skin care product that is more moisturizing, lasts longer, and can stay on the surface of the lips without penetrating them. This is lip balm. But what happens if you accidentally apply expired lipstick?

What happens if you apply expired lipstick?

If you use expired lipstick, there may not be any adverse reactions, perhaps because it has just expired and has not deteriorated much. If the expiration date is serious, it may be harmful to the skin of the lips, causing allergies, redness and swelling. Also, when you eat, expired lipstick enters the intestines along with food and may cause stomach pain or diarrhea.

How to tell if your lip balm is expired

1. 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 it has gone bad, because the lipstick will be oxidized when exposed to air after being opened. Expired or spoiled lipstick will have a pungent and strange smell. Because the decomposition of cosmetics by bacteria is a process of organic fermentation, the acidification reaction will emit a rancid smell, which will cover up the fragrance of the lipstick itself and will be very unpleasant.

2. Weakened effect

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.

3. The paste becomes dry

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

4. There are mildew spots

This is the simplest way to judge. Check 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.

5. Look at the color of the paste

If the cap of lipstick is not fastened tightly after use and the lipstick is left directly in the air, it will invisibly provide an opportunity for the growth and reproduction of bacteria. The pigments produced by bacteria during their growth and development can turn the lipstick yellow or black.

What to do with expired lipstick

1. It can be used to wipe hands and feet, moisturize the skin and help lock in skin moisture; it can soften dead skin after wiping feet.

2. It can be used to wipe oxidized silverware and silver jewelry with good results; apply lipstick on a finger towel, and then wipe the oxidized areas.

3. Can be used as shoe polish to polish leather shoes;

4. Use lubricant and wax on zippers. If the zipper is sticky, you can use expired lipstick to wipe it, because lipstick contains oily ingredients;

5. If there are self-adhesive stickers on the wall or the floor, which are difficult to remove, you can apply lipstick on them and then wipe them with a rag. They can be easily wiped off. There will also be some annoying marks from the bottom of teacups on the table. You can also apply lipstick on them and wipe them with a cloth.
