Pregnancy Skin Changes: What Causes Them, What's Normal, and What Fades

Pregnancy affects virtually every system in the body — and the skin is no exception. Hormonal changes, increased blood volume, immune modulation, and physical stretching all produce visible skin changes. Some women love what pregnancy does to their skin. Others find the changes distressing. Most have questions that go unanswered at routine antenatal appointments.
Dr. Shachi Singh, consultant gynaecologist and obstetrician at Prakash Hospital, Sector 33, Noida, explains the most common pregnancy skin changes — what causes each one, whether it is normal, and what fades after delivery.
Melasma (The Mask of Pregnancy / Chloasma)
Melasma is darkening of the skin in a symmetrical pattern — typically on the cheeks, forehead, upper lip, and bridge of the nose. In South Asian skin, it can appear very pronounced. It affects up to 70% of pregnant women and is significantly more common in women with darker skin tones.
1. Cause: Oestrogen and progesterone both stimulate melanocytes (the pigment-producing cells) to produce more melanin. Ultraviolet (UV) radiation from sun exposure markedly worsens this.
2. Triggers: Sun exposure in pregnancy — even brief, even on cloudy days — dramatically worsens melasma.
3. What to do during pregnancy: Strict, consistent sun protection is the single most effective measure. SPF 50+ broad-spectrum sunscreen applied every morning and reapplied every 2 hours if outdoors. Wearing a hat and seeking shade. Physical sunscreens (zinc oxide, titanium dioxide) are preferred in pregnancy over chemical UV filters.
4. After delivery: Melasma improves substantially in many women after delivery and the cessation of breastfeeding, as hormone levels normalize. It may not disappear completely without treatment. If it persists, dermatological treatments (azelaic acid, niacinamide, Vitamin C, and eventually tretinoin after breastfeeding) are effective.
5. Important: Many skin-lightening products marketed for melasma contain hydroquinone or high-dose retinoids — both should be avoided during pregnancy.
Linea Nigra
A darkened vertical line running from the navel down to the pubic area (and sometimes upward to the navel). Appears from the second trimester in most women. In lighter-skinned women it may be faint; in darker-skinned women it is often quite pronounced.
1. Cause: Hormonal stimulation of melanocytes — the same mechanism as melasma. The Linea alba (a faint white line that was always present) darkens under hormonal influence.
2. After delivery: Fades gradually over several months post-delivery. May not disappear completely but becomes much less visible.
3. No treatment is necessary and no treatment is proven to speed its fading during pregnancy.
The Pregnancy Glow

Many women notice their skin appears more radiant and flushed during pregnancy — particularly in the second trimester. This is real, not imagined.
1. Cause: Blood volume increases by 40 to 50% in pregnancy. Increased blood flow to the skin produces the flushed, luminous appearance. Slightly increased sebum (oil) production also contributes to a natural sheen.
Pregnancy Acne
Some women who had clear skin before pregnancy develop acne during pregnancy — particularly in the first trimester when progesterone spikes. Women who had acne before pregnancy often find it worsens.
1. Cause: Progesterone increases sebum production, which can block pores.
2. What is safe for acne in pregnancy:
- Gentle cleansing twice daily with a mild, non-comedogenic cleanser
- Topical azelaic acid (15 to 20%) — safe in pregnancy, effective for acne and pigmentation
- Topical glycolic acid — generally considered safe
- Topical erythromycin or clindamycin (antibiotics) — safe in pregnancy for moderate acne
3. What to avoid in pregnancy:
- Topical retinoids (tretinoin, adapalene, retinol) — teratogenic; absolutely avoid during pregnancy
- Oral isotretinoin (Roaccutane/Accutane) — absolutely contraindicated in pregnancy, causes severe birth defects
- Oral tetracyclines (doxycycline, tetracycline) — not safe in pregnancy after the first trimester
- Salicylic acid at high concentrations (low concentrations in some cleansers are generally considered safe)
Skin Tags
Small, soft, flesh-coloured protrusions — particularly in the neck, armpits, under the breasts, and in skin folds — are common in pregnancy. Oestrogen stimulates their growth.
1. After delivery: Many skin tags reduce in size or disappear. Those that persist can be removed by a dermatologist after delivery.
Prurigo of Pregnancy (Pregnancy Itch)
Mild generalised itching is common in pregnancy from stretching skin. However, itching that is intense and does not respond to moisturiser should be evaluated.
1. Intrahepatic cholestasis of pregnancy (ICP): Intense generalised itching — typically starting on the palms and soles and spreading — in the second or third trimester, often worse at night, is the hallmark of ICP. ICP is caused by impaired bile flow from the liver during pregnancy. It is associated with increased risk of preterm birth and stillbirth. Any woman with intense generalised itching in pregnancy must be assessed urgently — blood tests for liver function and bile acids are needed. ICP is treated with ursodeoxycholic acid and may require early delivery.
This is not the same as the mild stretching-related itch that responds to moisturiser.
Spider Veins and Varicose Veins
Increased blood volume and progesterone-related venous relaxation produce small spider veins (telangiectasias) on the face, neck, and upper chest in many pregnant women. Varicose veins of the legs — from the same venous relaxation and the pressure of the uterus on pelvic veins — affect many women.
1. After delivery: Spider veins on the face often fade. Varicose veins may partially improve but often persist, particularly after multiple pregnancies. Compression stockings during pregnancy reduce discomfort and slow progression.
Stretched and Itchy Skin
As the abdomen grows, the skin stretches and may itch — particularly over the abdomen. Regular moisturisation (any cream: cocoa butter, shea butter, almond oil, Bio-Oil) reduces the itch and improves comfort, even if it does not prevent stretch marks.

Frequently Asked Questions
1. Will the dark line on my belly (linea nigra) go away?
Yes — linea nigra fades gradually in the months after delivery as hormone levels normalise. It may take 3 to 6 months to become much less visible.
2. Is intense itching in pregnancy normal?
Mild itching from skin stretching is common and managed with moisturiser. Intense, generalised itching — particularly on the palms, soles, or that worsens at night — is a warning sign for intrahepatic cholestasis of pregnancy (ICP) and needs urgent blood tests. Do not dismiss severe pregnancy itch.
3. Are any acne treatments safe in pregnancy?
Topical azelaic acid, topical antibiotics (erythromycin, clindamycin), and gentle glycolic acid cleansers are safe options. Avoid all retinoids and oral tetracycline antibiotics during pregnancy. Oral isotretinoin (Roaccutane) is absolutely contraindicated in pregnancy.
