Does using lipstick often cause dark lips?

Many people think that dark lips are caused by overusing lipstick and not removing makeup thoroughly every day. So, does using lipstick regularly cause dark lips? (Lan, 22 years old)

The US Food and Drug Administration (FDA) recommends that the standard concentration of lead or heavy metals in lipstick should be lower than 10 ppm. If lipstick or any other product or cosmetic has a concentration of lead or heavy metals higher than the above prescribed level, it should not be used.

The reason is that lead in lipstick can easily cause changes in lip pigmentation. In addition, applying lipsticks containing irritants will accidentally cause inflammation in our lips, which then leads to increased pigmentation, making the lips darker. Fake lipsticks and lipsticks of unknown origin cause dark lips and affect health.

Lips are also a very sensitive area because the skin in this area is quite thin. Therefore, even using expensive lipsticks from big brands can still cause allergies.

To ensure safety, you should not buy cheap lipsticks of unknown origin because it is difficult to determine the ingredients. For genuine lipsticks, you need to read the ingredient list carefully to reduce irritation and ensure the lead concentration meets standards. You should buy lipstick at a reputable address to avoid buying high prices but low quality products.

Some other measures to care for lips include exfoliating once or twice a week. ‏Gently massage your lips, use lip balm to avoid dry lips, and help keep your lips smooth. ‏
