Pregnancy brings about many changes in a woman’s body as it adapts to support the growing fetus. While some of these changes are obvious, like a expanding belly and breasts, others are more subtle. One aspect that can change dramatically during pregnancy is the skin. The skin is the body’s largest organ and it undergoes some significant transformations in the first trimester of pregnancy due to hormonal fluctuations and increased blood volume. Understanding what’s happening under the surface can help expectant mothers know what to expect and how to best care for their skin during this time.
Increased Hormones
One of the main factors influencing skin changes in early pregnancy is the rapidly changing hormone levels. The placenta produces large amounts of estrogen and progesterone to support the developing baby. This increase in hormones stimulates the production of melanin, which causes darker pigmentation in certain areas. Many women notice a darkening of the areolas, nipples, genital area, and the midline of the lower abdomen, referred to as the linea nigra. These hormonal shifts can also cause melisma or chloasma, which is the development of tan or brown patches on the face, often called the “mask of pregnancy.”
Estrogen Effects
– Stimulates melanocytes leading to increased pigmentation
– Causes blood vessels to dilate, increasing blood flow
– Increases oil production, which can clog pores
Progesterone Effects
– Promotes skin cell growth
– Causes water retention, leading to swelling
– Slows down cell turnover, potentially causing breakouts
These hormonal changes are temporary and skin pigmentation often fades after giving birth and breastfeeding is discontinued. However, the increase in hormones can also have lasting effects like stretch marks, spider veins, and acne.
Increased Blood Volume
Another change that impacts skin is the increase in blood volume during pregnancy. Blood volume can increase by 30-50% to supply the developing placenta and fetus with oxygen and nutrients. This causes the blood vessels near the surface of the skin to dilate and become more visible.
Many women experience spider veins and reddened skin from the increased blood pooling close to the surface. The tiny capillaries around the nose and cheeks may rupture more easily, leading to rosy cheeks and a “pregnancy glow.” However, the influx of blood can also cause unsightly varicose veins, especially in the legs.
Blood Volume Increase Effects
– Vasodilation and visible blood vessels
– Spider veins and varicose veins
– Reddened skin and pregnancy “glow”
– Increased risk of broken capillaries and rosacea
This boosted blood flow is temporary and vessels should return to normal after delivery. However, varicose veins and broken capillaries may persist after pregnancy.
Increased Water Retention
Fluid retention is very common in the first trimester as the body holds on to more water to increase blood volume. The excess fluid is also used to support fetal development and growth. However, this swelling can impact the skin, especially in the hands, feet, legs, and ankles. Additional water pooled under the skin expands tissues, making them taught and uncomfortable.
Retaining water exacerbates the dilation of blood vessels, leading to further redness and visible veins. This uncomfortable swelling typically reduces after the first trimester when the body adjusts to the demands of pregnancy. However, wearing compression stockings, elevating the legs, and avoiding salty foods can provide relief from water retention.
Water Retention Effects
– Swelling of hands, feet, legs and ankles
– Expands tissues making skin feel tight
– Contributes to spider veins and varicose veins
– Most severe in first trimester then subsides
Increased Sweat Production
Hormonal changes like surging estrogen levels can also increase sweat gland activity. Many pregnant women report increased perspiration and body odor early in pregnancy. Night sweats are also very common due to rising progesterone which elevates body temperature. Excessive sweating can lead to common skin conditions like heat rash, yeast infections, and prickly skin.
Managing sweating during pregnancy involves wearing loose, breathable fabrics, showering frequently, avoiding spicy foods, and using gentle antiperspirants. It’s also important to keep the skin clean and dry to prevent any heat rash or fungal infections.
Sweating Effects
– Heightened perspiration and body odor
– Prickly heat or sweat rashes
– Yeast infections like candida
– Night sweats from rising temperature
– General skin irritation and prickliness
Skin Sensitivity
Many pregnant women comment their skin feels more sensitive during the first trimester. This is again related to the hormonal surges which boost blood flow to the surface of the skin. The influx of estrogen increases nerve endings and cell turnover in the skin, making it more reactive and delicate.
Skin may feel tingly or itchy without being dry or irritated. Even typically well-tolerated lotions and cosmetics may cause red, flushed skin. Gentle products should be used to cleanse and moisturize sensitive areas. Cool showers, fragrance-free products, and loose clothes can help prevent irritation.
Skin Sensitivity Effects
– Heightened reaction to products and fabrics
– Prickly, itchy skin without a rash
– Redness and flushing easily
– Tingling or irritated skin from lotions
– Difficulty tolerating typically well-tolerated products
Acne and Breakouts
One of the most frustrating skin changes during pregnancy is the development of acne. Surging hormone levels increase oil production which clogs pores. The estrogen stimulates quicker skin cell turnover but the dead cells build up when oil blocks them from shedding.
Pregnancy acne often occurs along the jawline, cheeks, and chin. Existing acne may also flare up during this time. Unfortunately, typical acne medications like retinoids, benzoyl peroxide, and oral antibiotics are not considered safe during pregnancy. Managing acne involves gentle cleansing, over-the-counter azelaic acid, and avoiding picking or popping pimples.
Acne Causes
– Increased oil production
– Slower cell shedding from surface
– Buildup of dead skin cells
– Hormone fluctuations
– Product and food sensitivities
Acne Treatments During Pregnancy
| Safe | Avoid |
|---|---|
| Gentle facial cleansers | Prescription oral antibiotics |
| Over-the-counter azelaic acid | Topical retinoids |
| Natural oil-free moisturizers | Harsh abrasive scrubs |
| Diluted tea tree oil spot treatment | Benzoyl peroxide |
| Oil blotting sheets | Salicylic acid |
Linea Nigra
Around 75% of pregnant women develop a dark vertical line running from the navel to the pubic bone called the linea nigra. This hyperpigmentation occurs due to hormonal changes that deposit increased melanin along connective tissues and tends to appear around week 12 to 16 of pregnancy. The darkness of the linea nigra varies greatly between women from light brown to almost black.
This odd midline stripe does eventually fade after pregnancy. However, women with darker complexions may notice a faint line for months or years after delivery. Using sunscreen on the area can help it fade more quickly after birth.
Linea Nigra Features
– Dark vertical line from navel to pubic bone
– Caused by hormonal increase in melanin
– Occurs in around 75% of pregnancies
– Usually appears between weeks 12-16
– Fades gradually after pregnancy
Itchy, Dry Skin
Many pregnant women also complain about itchy, dry skin during pregnancy. As estrogen levels peak, it triggers the liver to produce more bile to aid digestion. This reduces the production of bile salts circulating in the blood that help skin retain moisture. With less bile salts, skin becomes drier and more prone to itching.
Dry skin leads to flaking, cracking, eczema, and stretch marks. Managing dryness involves diligent moisturizing and hydration. Opt for thick, oil-based body creams and minimize use of irritating soaps. Drinking plenty of water is also key to providing moisture.
Causes of Dry, Itchy Skin
– Hormone changes redirect bile salts
– Lack of bile leads to poor moisture retention
– Skin barrier is compromised
– Deficient hydration and nutrition
– Climate and seasonal weather changes
Stretch Marks
Up to 90% of women develop stretch marks during pregnancy as the skin expands to accommodate the growing baby. Stretch marks often form on the abdomen but can also occur on the breasts, thighs, hips, and backside. They appear as reddish or purplish streaks that eventually fade to leave silvery scars.
Genetics play a major role in stretch mark development, but keeping skin moisturized can help minimize their appearance. Applying coconut oil, shea butter, or jojoba oil daily helps hydrate and improves elasticity to prevent tearing. However, some stretch marks are inevitable from the dramatic uterine expansion.
Stretch Mark Features
– Occurs in up to 90% of pregnant women
– Caused by skin stretching rapidly
– Most common sites are abdomen, breasts, hips, thighs
– Start as reddish or purple streaks
– Fade to leave white/silvery scars
– Genetics determine susceptibility
Mask of Pregnancy (Melasma/Chloasma)
Up to 70% of pregnant women develop hyperpigmentation on the face known as melasma or chloasma. This darkening of the skin occurs when estrogen and progesterone stimulate excess melanin. It typically manifests as large tan or brown patches on the forehead, nose, cheeks and chin that resemble a “mask.”
Melasma can be challenging to treat during pregnancy and may not fully resolve until after delivery. Using diligent sun protection and avoiding skin irritants is recommended. Chemical peels and certain lasers that impact pigment cannot be performed until after pregnancy and weaning.
Melasma Features
– Hyperpigmentation on the face
– Patchy tan or brown “mask” pattern
– Caused by estrogen causing excess melanin
– Affects up to 70% of pregnant women
– Hard to treat during pregnancy
– May take months to fade after birth
Spider Veins
Up to 40% of pregnant women develop spider veins, especially during the second and third trimesters. These small purple or red veins sprout up on the surface of the skin, most commonly on the face and legs. The exact cause is unknown, but the boost in estrogen and progesterone likely weakens venous valves.
Spider veins can disappear on their own after pregnancy, but some may require laser therapy for permanent removal. Wearing compression stockings can help reduce swelling and damage to valves in the leg veins. Elevating the legs periodically can also prevent blood pooling during pregnancy.
Spider Vein Causes
– Weakened venous valves
– Hormone fluctuations
– Increased blood volume
– Genetic predisposition
– Pressure from growing uterus
Spider Vein Treatment
– Some fade naturally after birth
– Wear supportive compression stockings
– Keep legs elevated when resting
– Laser therapy for persistent veins
– Further pregnancy can worsen veins
Hair and Nail Changes
Pregnancy hormones can also impact hair and nails. Many women enjoy strong, shiny locks during pregnancy with less shedding and breakage. However, some may also develop hair growth in unwanted places like the face, back, and belly. Hormones can also shift hair texture and curl patterns.
Nails become more prone to splitting and cracking during pregnancy. A daily prenatal vitamin helps provide nutrients for strong nails. Biotin supplements also help boost nail thickness and hardness. Use cuticle cream and moisturizer daily to condition the nail bed.
Hair Changes
– Increased thickness and growth
– Enhanced shine and strength
– New hair growth on body
– Changing texture or curl pattern
– Hair eventually returns to normal
Nail Changes
– Increased dryness and brittleness
– Peeling, cracking, splitting
– Prevents nutrient absorption
– Need moisture and biotin
– Return to normal after pregnancy
When to See a Doctor
While most skin changes during early pregnancy are normal, it’s a good idea to mention concerns to your doctor. Seek medical care promptly for:
- Extreme itching without a rash
- Sudden acne with oozing or crusting
- Facial redness accompanied by swelling
- Blistering skin conditions
- Signs of heat rash or fungal infection
Some skin issues during pregnancy can indicate an underlying disorder like intrahepatic cholestasis or be associated with complications. Always check with your practitioner when something seems abnormal or severe.
Summary
Pregnancy sets off a cascade of skin changes due to hormonal fluctuations, increased blood volume, and heightened sensitivity. Common symptoms like acne, dry skin, darkening pigment, and stretch marks are often temporary and resolve after delivery. While mostly benign, significant itching, swelling, extreme dryness, and irritation warrant medical evaluation. With diligent skin care and moisture, most pregnant women can manage the modifications successfully.
