There are spots on the body, some people don't care, some people suspect that it is a disease. Dermatologists say the vast majority of spots, including sunburns, age spots and freckles, are related to sunlight, aging or constitution. Spots related to sun exposure and genetics are usually not a health problem.
Young people with age spots
The official name for age spots is seborrheic keratosis, and many people often mistakenly believe that age spots only appear in the elderly.
Seborrheic keratosis is a benign hyperpigmentation of the keratin and epidermis, which, together with hyperpigmentation, produces brownish raised granules on the face, usually associated with sun exposure and aging. Some young people will grow on the chest, abdomen or back, which is caused by the constitution.
Freckles and sunburns are similar in appearance and are related to ethnicity or constitution. Westerners are fair-skinned, and many boys and girls have freckles on their faces during puberty. Zhuang Yahui said that the same kind of freckles may be affected by different factors, such as freckles will become more obvious under the sun.
Other clinically common plaques include liver plaques, Ota plaques, zygomatic plaques, and Baker's plaques.
Cheekbone mother spots are more common on the cheekbones of the cheeks. They are more common in Orientals and are also genetically related. A rubidium-chromium laser may lighten them temporarily, but it's not easy to remove them completely.
A few people are born with blue-gray birthmarks on their faces. This is Ota's mother point. If it obviously affects the child's appearance and psychological development, it is recommended to do rubidium or rubidium chrome laser treatment.
Most of Baker's female spots are on the chest, back, and upper limbs. They are brown flakes, sometimes spotted with some hair on them. It often takes multiple laser treatments to subside, and recurrence is easy. If the patient really wants to get better, Zhuang Yahui suggested that rubidium chromium or rubidium laser can be considered; if combined with hair removal, Alexander laser or diode laser can be selected.

Ota female spots and Baker's female spots are genetically related to embryonic development and belong to benign spots; Sun spots, age spots, freckles, and female cheekbones are also benign and do not affect health, and generally do not require special treatment unless they are aesthetically pleasing.

Liver spots have nothing to do with liver problems, taking hepatoprotective drugs is ineffective
Many people literally think that liver spots are caused by liver problems. There was even a woman who swallowed liver-protecting pills because of liver spots on her cheeks. In fact, liver spots get their name only because they are similar in color to pig livers.
Presidential liver spots are mainly due to their constitution, and they tend to occur in women. Chen Xuanxiang said that some women had liver spots on their faces that were not obvious or even grown before pregnancy, but they actually appeared after pregnancy. Not only pregnancy, but taking oral contraceptives can also affect hormonal changes and induce liver spots. Postpartum liver spots may subside slightly, but not completely, and may reappear in the next pregnancy.
Freckle cream is not a panacea
For those who really care about liver spots on the face, Chen Xuanxiang recommends rubbing with a three-in-one external medicine of steroids, hydroquinone, and tretinoin under the guidance of a doctor for 4-8 weeks. , but it is not recommended that patients go to the pharmacy to buy, so as not to rub the wrong time or dose, which may cause skin irritation or damage.
Depigmentation creams are usually only effective on superficial spots such as freckles and liver spots. The ota and zygomatic macules that grow in the dermis must be faded with a laser.
The more spots that grow, the more likely you are to get skin cancer?
It may seem difficult to judge the likelihood of cancer based on the number of spots alone. Zhuang Yahui believes that although some people have no spots on their faces, a malignant mole that looks like a spot suddenly appears on their faces, which may be skin cancer.

Age, constitution and long-term sun exposure, the more sunburn and seborrheic keratosis, the higher the chance of developing skin cancer.

Pigmentation after trauma and inflammation, not spots.
In addition to the common spots mentioned above, post-inflammatory hyperpigmentation is often confused with dark spots.
Some people call this condition post-inflammatory hyperpigmentation, but it's not really a medical definition, such as having been traumatized, having a broken car, having a knife, acne, eczema, or being bitten by a mosquito. Causes skin inflammation, the melanin originally in the epidermis falls to the dermis layer, leaving a dull color in the wound. This is post-inflammatory hyperpigmentation.
How to tell if it's a spot or skin cancer?
These 5 criteria can be used to compare the appearance of a mole when it is uncertain whether it is a benign or malignant melanoma.
Another skin condition to watch out for is basal cell carcinoma, which is associated with prolonged sun exposure. Basal cell carcinomas look like moles, sometimes mixed with other spots on the face. Some people don't care. When the skin festers, basal cell carcinoma has penetrated under the skin, invading bone or muscle, and destroying normal tissue.
If you observe a disc around the mole, an ulcer in the middle depression, and a pearly or brown appearance, it may be a basal cell carcinoma, as was the case with movie star Hugh Jackman. However, such cancer cells are generally less likely to metastasize, and if detected early and removed, the prognosis is good.
