During pregnancy, due to changes in body内分泌, some pregnant women may experience spots on their face, which has nothing to do with eating vinegar. Eating vinegar is not a trigger for spots. At this time, it is important for pregnant women to understand which type of spots they have and to adopt targeted care. It is essential to keep the skin clean and to do a good job of sun protection.

1. Freckles

Symptoms: They are usually symmetrical in shape, with each spot being isolated and not merging into patches, ranging in size from needle尖 to bean size, with both circular and elliptical shapes, with a smooth surface and no symptoms upon occurrence.

Causes: Freckles are caused by the accumulation of melanin in the skin, usually due to sun exposure, where tyrosine in the skin is oxidized by ultraviolet light to form dopamine, which is then converted to form melanin. Generally, no medical treatment is required.

Affected Population: Freckles are more common in women without sun protection habits, and those with fair skin are more prone to them. In men, due to thicker stratum corneum, spots are less common.

Method: The approach to dealing with spots is primarily preventive, combined with whitening and spot removal remedies. To prevent freckles, sun protection is essential, which not only includes applying sunscreen but also using hard protective measures such as umbrellas and sun hats, especially during frequent outdoor activities in summer, where it is important to apply high-SPF sunscreen regularly.

2. Melasma

Symptoms: These spots are usually yellow-brown or dark brown, commonly known as freckles, liver spots, or pregnancy spots, often occurring on the cheeks, forehead, nose, and around the mouth, forming butterfly-shaped patches with a smooth surface and no symptoms upon occurrence.

Causes: The formation of this type of spots is largely attributed to endocrine disorders, imbalanced hormone levels, liver dysfunction, and chronic inflammatory pigmentation deposits caused by skin barrier damage, which are very difficult to treat.

Affected Population: Women are more susceptible, especially during pregnancy, irregular menstruation, or those with ovarian or uterine diseases.

Method: Topical skincare products with high-efficiency anti-melasma ingredients can alleviate melasma, but due to its stubbornness, it is generally recommended to combine it with oral medications for treatment, such as tranexamic acid and glutathione. At the same time, it is advisable to consume foods rich in vitamin C or take vitamin C supplements internally.

In addition, optical lightening methods can be used to remove melasma, which is relatively difficult to remove. It requires a long-term use of lightening products to achieve the desired effect, and one should not seek immediate results. Moreover, maintaining a good mood and adequate sleep is essential to ensure normal internal bodily functions and to restore hormones to a stable level.
