Don't confuse freckles with xeroderma pigmentosum

People often think that the kind of small spots on the face are called freckles, once spots appear on the face, people often choose freckle removal products or treatments according to the method of removing freckles, but not spots or freckles, and it may be that you have xeroderma pigmentosum, freckles only affect the appearance, and xeroderma needs to be treated.

Freckles are a yellowish-brown or dark-brown spotted spot that is commonly found on the face. Some have a genetic predisposition. It appears more often than 3-5 years old, more in women, and increases with age. These brown spots tend to appear on the face (especially the nose and cheeks), neck and shoulders, but can also appear on the backs of the hands and the dorsum of the feet. There are generally no uncomfortable symptoms such as pain and itching. It is generally aggravated in summer and tends to be reduced in winter.

However, some punctate spots may be xeroderma pigmentosa and can be easily confused with freckles, especially in mild patients. This disease also occurs soon after birth, and the pigmentation will deepen after sun exposure to the skin, and erythema may occur, resulting in heterochromia-like changes in the skin, and the rash does not subside in winter, and the skin tone is darker, and there is a familial genetic tendency. The course of the disease is prolonged, gradually worsening, and finally it can become carcinogenic, forming squamous cell carcinoma or basal cell tumor.

Another disease that is often confused is hyperpigmentation, which is a skin condition that runs in families. Onset begins soon after birth, with freckle-like punctate pigmentation on the front, dorsum of hands, and dorsum of feet. If preventive measures are not taken in time, it can spread to the limbs and trunk.If the genetic characteristics of the family are obvious, genetic diagnosis can be carried out through molecular genetics technology, and prenatal diagnosis can also be used to prevent and pass the disease on to the next generation.

Therefore, if you have spots on the face or other parts, don't just think that freckles do not need to be treated, but also see if there are other symptoms of xeroderma colora, for this disease, the use of freckles removal products and whitening products is not effective, you must go to the hospital dermatology for examination and treatment.
