What are the causes of black spots on lips?

Studies have found that there are many reasons for the appearance of dark spots on the lips. First, the lip skin is exposed to the sun for a long time, and pigmentation easily occurs after being exposed to ultraviolet rays. Second, the use of inferior lip oils causes pigmentation or is caused by skin allergies. Third, it is caused by endocrine disorders and digestive disorders in the body. The last point is caused by premature skin aging.

1. Causes of black spots on lips

1. If people's facial skin is exposed to the sun for a long time, especially when it is directly exposed to ultraviolet rays without any cover, it is easy to cause pigmentation.

2. After using inferior cosmetics or long-term use of cosmetics that are inconsistent with the properties of one's own skin, some people's skin will have allergic reactions or inflammation, which can also lead to pigmentation and the formation of

Black spots on lips.

3. Female endocrine (hormone) disorders, digestive dysfunction (such as long-term constipation), liver dysfunction, excessive mental stress, severe lack of sleep, anemia and other reasons can cause the formation of black spots on the lips.

4. In addition, premature aging of the skin is also one of the important reasons for the formation of black spots on the lips. The epidermal cells on the face are usually replaced every 25 to 30 days. If the skin metabolism is active, even pigmentation will disappear naturally in a relatively short period of time as the stratum corneum falls off. As we age, the skin's metabolism declines and the natural repair ability of the skin's stratum corneum decreases. As a result, the deposited pigments are difficult to fade and turn into dark spots.

2. How to maintain the skin of lips and get rid of small black spots

1. Choose lip care products carefully. Girls who have dark spots on their lips must choose lip care products carefully and avoid using dark-colored lipsticks and lip glosses on large areas. In addition, when choosing lip balm, you should read the ingredients carefully to avoid those containing too many chemicals that may irritate the lips. Choose a simple lip balm containing ingredients such as glycerin to moisturize your lips.

2. Use appropriate force when removing lip makeup. Our lips also need makeup removal, especially for girls who often wear makeup. When removing lip makeup, you need to be careful. Excessive cleansing and excessive force in removing makeup will damage the fragile and delicate skin of the lips. If the makeup is not removed thoroughly, melanin will also be deposited on the lips. It is recommended that girls apply a hot towel before removing lip makeup every time, so that makeup removal will be easier. After removing lip makeup, remember to apply lip balm to give your lips enough protection and nourishment.

3. Make your own lip mask to lighten dark spots on your lips. Girls with dark spots on their lips can make their own lip masks to lighten the melanin on their lips. Applying tomatoes, lemons, milk, etc. directly on the lip skin can all help lighten the dark spots. The key is to persist for a long time. The effect may not be obvious once or twice.
