Skin darkening during pregnancy is a commonly observed phenomenon. Also known as hyperpigmentation, skin darkening occurs in the form of patches or patterns on the skin.
Some common places where you might notice these patches include the linea nigra (a dark line moving across the belly), melasma (patches on the face), chloasma (patches on cheeks, upper lip, forehead, and chin), and the darkening of the areola (1). These marks are more prominent in those with dark-colored skin. This condition may also lead to the darkening of birthmarks, freckles, or scars during pregnancy.
Read on to know more about the causes, treatment, and prevention of skin darkening during pregnancy.
Key Pointers
- Hyperpigmentation in certain areas such as the areola, face, and belly may result from an increase in hormones during pregnancy, excessive sun exposure, heredity, or hyperthyroidism.
- The risk of skin pigmentation can be reduced by using sunscreen lotions and moisturizers, taking folic acid, and avoiding waxing.
- Lemon juice, aloe vera, turmeric, potato extract, orange peel, and yogurt are some home remedies that can help exfoliate the skin and manage pigmentation.
- Melasma may fade automatically post-pregnancy once hormone levels return to normal and may recur only during subsequent pregnancies.
What Causes Skin Darkening During Pregnancy?
Many women experience skin changes, such as stretch marks, acne, or dark spots during pregnancy (1). The exact cause of skin darkening or skin discoloration in pregnancy is not entirely known. It is often attributed to increased levels of certain hormones during pregnancy such as estrogeniA sex hormone produced by the body that facilitates sexual and reproductive development , progesteroneiAn endogenous steroid sex hormone that regulates the menstrual cycle, pregnancy, and other hormonal functions in women , and melanocyteiPigment cell that produces melanin -stimulating hormones (1). Also there is stretching of skin leading to aggravation of these changes. The StatPearls Publishing highlights that around 15% to 50% of pregnant women have melasma.
Some other factors that may also increase the possibility of skin darkening (or melasma) in pregnancy are (1) (2):
- Environmental factors such as UV radiation
- Pre-existing conditions such as hyperthyroidism (overactive thyroid)
- Heredity (if melasma runs in the family). Research shows that skin darkening is common in people with darker skin tones, primarily in those of East Asian, Southeast Asian, and Hispanic origins (3).
When Does Skin Darkening/ Discoloration Happen During Pregnancy?
More than 90% of pregnant women experience some sort of skin changes (4). The increasing estrogen and progesterone levels may contribute to increased melanin production (5). It might start as early as the first trimester.
- Starting from the first trimester, you may notice the darkening of the areola, and genital regions.
- Linea nigra may become noticeable in the second trimester.
A blogger who goes by the name DPrincess28 faced skin-darkening issues during pregnancy. Sharing her experience, she elaborates, “For me, I didn’t experience darkening on my face or neck. Instead, my belly became dark, as did some of the skin around my thighs and buttocks (i).”
All of these usually resolve in a few months after delivery (4). However, some of these may remain forever although in a lighter tone.
How Can You Reduce Pigmentation During Pregnancy?
Skin changes usually disappear after delivery. However, you may take some measures to minimize the darkening of the skin in pregnancy.
- Protect yourself from strong sun rays: Exposure to the sun is one of the most significant factors that trigger pigmentation. Use a broad-spectrum sunscreen that has an SPF of 30 or higher as a part of your everyday skin routine. When going outdoors, cover yourself with a long-sleeved dress and a wide-brimmed hat (6).
- Take enough folic acid: Skin changes may also occur due to folateiAlso known as vitamin B9, it is mainly responsible for producing red and white blood cells in the body deficiency. Therefore, make sure you are getting enough of it either from your diet or through supplements (7).
- Do not wax: Although waxing is likely to be safe during pregnancy, it may cause skin inflammation that could worsen melasma. Therefore, do not wax the areas that are prone to pigmentation (8).
- Use hypoallergeniciA product with the least amount of allergy-inducing components skincare products: Choose cleansers, moisturizers, or face creams that will not burn or irritate your skin and worsen melasma (8). Topical corticosteroids may also help in fading pregnancy melasma.
You may not be able to prevent the uneven skin tone caused by pregnancy. You may consult a dermatologist if it gets severe. Using a good moisturizer throughout pregnancy over these sensitive areas may also reduce the severity of these marks and skin damage. Additionally, eating healthy foods and drinking plenty of water is important to support skin health.
Home Remedies To Manage Skin Darkening During Pregnancy
Here are some home remedies that have been traditionally in use to lighten the dark patches on the skin. Most of the uses are anecdotal.
1. Lemon:
Lemon juice has skin bleaching properties and could help reduce dark spots and blemishes (9).
How to use:
Dilute two tablespoons of lemon juice in some water. Dip cotton into the solution and apply it over the affected skin region. Leave for sometime before washing it off.
2. Turmeric:
Curcumin, a polyphenol compound in turmeric, is reported to suppress the activity of melanocytes (10).
How to use:
Mix raw turmeric paste with lemon juice. Apply the mixture to the skin and allow it to dry. Wash off with water.
3. Potato:
Azelaic acid content in potato is found to reduce pigmentation and spots (11).

Quick tipWhen Does Your Skin Get Back To Normal?
Pregnancy skin changes such as dark patches, blotches, and lines tend to fade away after delivery as the hormone levels go down. In some cases, melasma which is also known as ‘pregnancy mask’ may recur in subsequent pregnancies or on the use of contraceptives (17).
Does Skin Darkening During Pregnancy Tell Something About The Baby’s Gender?
In some cultures, people relate skin pigmentation or pregnancy glow to the gender of the baby. However, there is no scientific evidence to support this.
Frequently Asked Questions
1. Does the dark neck go away after pregnancy?
Melasma may also affect the neck region. However, if it has occurred during pregnancy, then it is likely to fade away a few months after childbirth (19).
2. Does skin darkening affect my baby?
No, skin darkening has not been found to be associated with any adverse fetal outcomes.
3. Can low iron cause skin darkening in pregnancy?
Some studies suggest low iron may be associated with melasma (20). However, more research is required to support the findings.
4. Does folic acid make my skin darker?
According to Dr. Anna H. Chacon, a board-certified dermatologist from Miami, Florida, “There is no scientific evidence to suggest that folic acid has any effect on skin pigmentation. However, changes in the skin due to deficiencies in folic acid levels are often characterized by paleness, attributed to anemia.”
Pregnancy hormones can be the reason for hyperpigmentation or skin darkening during pregnancy. In addition, environmental factors such as sun exposure, pre-existing diseases such as hyperthyroidism, and hereditary factors may increase the risk of developing darker skin in pregnancy. Hyperpigmentation can be more evident in the areola of the breasts and genital areas. A dark line called linea nigra can also appear along the abdomen during pregnancy. Avoiding waxing and sun exposure and taking prenatal vitamins such as folic acid may reduce skin darkening in pregnancy. These pigmentations tend to fade after delivery as the hormones decline without any specific treatments.
