What is the difference between freckles and chloasma?
Both freckles and chloasma are caused by the deepening of facial pigmentation, but freckles are generally related to genetic factors, while chloasma is acquired and related to endocrine disorders or hormone secretion disorders in the body. Of course, in addition to this difference, there are differences in appearance and age.
1 is formed for different reasons: genetic genes can cause freckles and chloasma, but it has a greater impact on freckles. And the acquired factors that cause the two are different. Freckles are caused by excessive mental stress, improper diet and sun exposure. Chloasma is caused by pregnancy, lack of vitamins, drug abuse, use of inferior cosmetics and diseases.
2, the shape and distribution range are different: freckles are mostly "sesame-like", mainly distributed in people's faces, necks, arms and other places that are easily exposed to the sun. Chloasma is an irregular spot, mainly distributed around the nose, eyes, mouth, cheeks, eyebrows and forehead.
3. Age and sex are different: Freckles are largely influenced by genetic factors, mostly occurring in teenagers. There is little gender difference, and the ratio of male to female is almost the same. Chloasma mostly occurs in people aged 30-50, especially pregnant women, postpartum women and menopausal women.
