What types of skin changes happen during pregnancy?
Changes in the skin are common during pregnancy. Many of
the changes are caused by the higher levels of hormones
during pregnancy. For example:
- You may notice a darkening or redness of skin in some
places.
- Stretch marks may develop from your increase in weight.
- Your skin may itch and become red.
- Small flaps of skin called skin tags may form.
- Hair may grow on the face or chest.
- Spider veins or varicose veins may develop.
Some normal changes in your skin and hair are described
below. Be sure to talk to your health care provider if you
notice any unusual skin changes or have any questions about
caring for your skin.
Where does the skin get darker?
One of the changes you might notice early in your pregnancy
is a darkening of the skin on or around your nipples. Later
in your pregnancy, you may see a dark line on your skin that
runs down your abdomen from your belly button to your pubic
hairline. This line is called the linea nigra, or black
line. You might also have blotchy brown spots on your
forehead, nose, or cheeks, a skin change called melasma,
chloasma, or the mask of pregnancy. The inner thighs may
become darker. Freckles, moles, and scars may also seem
darker.
The darkening of the skin is caused by the increased amounts
of hormones during pregnancy and an increase in the
substance called melanin that is made by your body to give
color to your hair, skin, and eyes. Skin darkening is more
common in darker-skinned women. Most of these changes will
fade or go away after delivery. The skin darkening is made
worse by exposure to the sun. Using sunscreen when you are
outdoors may help prevent it. Do NOT use skin-bleaching
treatments when you are pregnant.
What are stretch marks?
Stretch marks are pink or purple streaks in the skin,
usually over the thighs, hips, abdomen, and breasts. They
are caused by the stretching of the skin as you gain weight.
They usually appear during the sixth and seventh months of
pregnancy. More than half of all pregnant women develop
stretch marks. They are much more likely to happen in women
with light skin color. While creams and lotions can keep
your skin well moisturized, they do not prevent stretch
marks from forming. Most stretch marks fade after delivery
to very light-colored lines, but they often do not go away
completely. When you are not pregnant, putting retinoid
products, such as tretinoin, on the stretch marks may help
them fade. Do NOT use this medicine while you are pregnant.
What causes itching?
The higher levels of hormones and stretching skin during
pregnancy, especially over your abdomen, can cause itching.
The palms of your hands and soles of your feet may also
become red and itchy. The best treatment is to use a
moisturizer after bathing and several times throughout the
day. Use only gentle soaps to wash your hands or clean your
skin, and avoid hot showers or baths that can dry your skin.
The itching usually goes away after delivery. Try not to
get too hot, since heat rash can make the itching worse.
Talk with your health care provider if:
- The itching keeps you awake.
- You have a rash.
- You have nausea, vomiting, less appetite, and are more
tired than usual.
What are skin tags?
Skin tags are tiny, floppy growths of skin that can occur
anywhere but more often are found in or near the armpits or
breasts. They are harmless. If they cause discomfort and do
not go away after pregnancy, they can be easily removed by
your health care provider with freezing, tying off with a
thread or stitch, or cutting off.
What changes are there in hair growth?
You may find that hair is growing in places where only men
normally grow hair, such as the face and chest. This growth
of hair is caused by the higher levels of hormones. It
usually stops and most of it goes away within 6 months after
delivery.
One to five months after your baby is born, you may lose
more hair from your scalp than usual. This loss of hair
happens because during pregnancy more hairs go into the
resting phase that is part of the normal growth and loss
cycle of scalp hair. Six to twelve months after delivery
your hair will become thicker again. This condition does not
cause permanent hair loss or obvious bald patches.
What are spider and varicose veins?
Spider veins are common during pregnancy. They start out as
small red veins that grow into the appearance of a roadmap
of red, blue, and purple streaks. They usually occur on the
legs during the second trimester but fade after delivery. If
these don't go away, talk with your provider about treatment
options.
During pregnancy, pressure on the large veins behind the
uterus causes the blood to slow in its return to the heart.
This means there is more blood in the veins of the legs than
when you were not pregnant. This can lead to swollen veins,
called varicose veins, in the legs. They are usually raised
above the surface of the skin. They can be twisted or
bulging and are dark purple or blue. You can try to prevent
varicose veins by:
- Not standing or sitting for long periods of time.
- Not wearing tight knee-high stockings or garters.
- Sitting with your legs and feet raised when possible. If
you work at a desk, you can prop your feet up on a
footstool, box or several books. Or when relaxing at
home, keep your feet up on a footstool, some pillows on
the couch, or another chair.
- Walking often to help increase circulation.
