Postpartum Skin Changes: How Long Each One Lasts

Most postpartum skin changes are pigment changes, and those usually fade in the months after birth. Stretch marks lighten and flatten but rarely disappear, and acne follows no set timeline.

You might be a few months out, still seeing a dark patch on your cheek or a line down your belly. If you're breastfeeding, every label seems to tell you to ask your doctor. Here is what each change tends to do, and what you can put on your skin while you nurse.

How Long Do Postpartum Skin Changes Last?

It depends on the change. Pigment usually settles within months, while stretch marks fade slowly and leave some trace.

• The dark line on your belly (linea nigra): a 2023 review in American Family Physician says it resolves within a few months of delivery.
• Melasma: it often clears after birth, but the American Academy of Dermatology (AAD) says it sometimes stays for years.
• Stretch marks: Mayo Clinic says they often fade over time but may never disappear completely.
• Acne: the AAD doesn't give a postpartum timeline. The 2023 review says higher androgen levels can worsen acne, especially in the second and third trimesters.
• Dry skin that starts 4 to 8 months after birth: worth a thyroid check, covered below.

Does Melasma Go Away After Pregnancy?

Often, yes. The 2023 American Family Physician review says melasma resolves after birth in 90% of cases.

The AAD says rising estrogen and progesterone are thought to trigger melasma in pregnancy. It may clear on its own, often after you give birth. Sometimes it stays around for years.

Melasma is more common in medium and dark skin tones, according to the same AAD page. Sunlight pushes your skin to make more melanin, so sun keeps patches dark. That's why the AAD pairs sun protection with every melasma treatment plan.

For sunscreen, the AAD recommends broad-spectrum SPF 30 or higher, with zinc oxide, titanium dioxide or iron oxide. It suggests a tinted formula if you get a white cast. While breastfeeding, LactMed, the NIH database on medicines and breast milk, says mineral sunscreens with titanium dioxide and zinc oxide may be better choices.

LactMed also says products with oxybenzone, octinoxate or enzacamene should probably be avoided while nursing. Check the active ingredients on the label, not the brand name. A wide-brimmed hat and shade cut how much chemical sunscreen you need.

Which Melasma Treatments Are Safe While Breastfeeding?

Each common melasma treatment has a LactMed entry, and most come with the same rule: keep your baby's skin off the treated area. The AAD says results usually take 3 to 12 months, and longer for older melasma.

• Hydroquinone: LactMed says it has not been studied during breastfeeding. It isn't ruled out, but some experts advise against long-term use while nursing. The AAD notes it's no longer sold without a prescription.
• Tretinoin cream: LactMed rates it a low risk to the nursing infant because little is absorbed through the skin. Don't apply it to the nipple or areola.
• Azelaic acid: the AAD lists it as a gentler prescription option. LactMed calls it low risk, since about 4% is absorbed. Keep it off the breast.
• Tranexamic acid pills: the AAD says studies show it can lighten patches when other treatments fail. LactMed says amounts in breast milk appear low and expert opinion supports breastfeeding during treatment. The FDA label is more cautious, advising use while nursing only if clearly needed. Not for anyone with a clot history, and ask about timing if you gave birth in the last 3 months (see below).

Tranexamic acid pills work against your body's clot-breaking system, so they aren't for everyone. The FDA label says they shouldn't be prescribed if you have or have had a blood clot, or have a condition that raises clot risk.

The label also warns that hormonal birth control may raise that clot risk further. The CDC says your risk of a dangerous blood clot stays higher up to 3 months after giving birth, and a C-section nearly doubles it. If you're within 3 months of delivery, had a C-section, or use hormonal birth control, ask your dermatologist whether to wait.

If you have leg swelling, pain or warmth, chest pain, trouble breathing or you cough up blood, get emergency care. Melasma treatments that work goes deeper on peels and lasers.

Will My Stretch Marks Fade After Pregnancy?

They will lighten, but they may never disappear completely. The AAD describes a stretch mark as a type of scar that forms when skin stretches quickly.

New marks can be red, purple, pink, reddish-brown or dark brown, depending on your skin color. In time the color fades and the bands sink below the surface. Mayo Clinic says they're common in pregnancy, especially in the last trimester.

Timing matters. The AAD says creams are most likely to help early stretch marks and seem to have little effect on mature ones. In studies, hyaluronic acid and tretinoin made early marks less visible, so the months while they're still colored are your window.

If you're breastfeeding, the AAD says to check with your doctor before treating stretch marks, because some ingredients, such as retinol, can harm your baby. LactMed's low-risk rating for tretinoin cream excludes the nipple and areola. Lasers can make marks less noticeable but can't remove them, according to the AAD.

Why Am I Breaking Out After Having a Baby?

There's no official timeline for postpartum acne. What LactMed does give is a usable list of treatments for while you're nursing.

• Benzoyl peroxide: LactMed says about 5% is absorbed, so it's considered low risk. Use creams or gels on the breast, not ointments, which can expose your baby to mineral paraffins if your baby licks your skin. LactMed also says to keep your baby's skin off treated areas.
• Azelaic acid and tretinoin cream: low risk, as above, with the same nipple and skin contact rules.
• Spironolactone: LactMed says it appears acceptable during breastfeeding. The AAD warns it can cause serious birth defects, so stop it and tell your doctor if you become pregnant again.

That AAD page also lists isotretinoin and tazarotene as unsafe in pregnancy, and most experts stop adapalene and tretinoin. Bring this up if you're planning another baby. On brown and Black skin, breakouts can leave dark marks behind. Why acne marks last longer on dark skin covers how to fade them.

Could Dry Skin After Pregnancy Be Your Thyroid?

It could, especially if it starts a few months after birth. The American Thyroid Association (ATA) says postpartum thyroiditis affects about 5% to 10% of women in the US.

The overactive phase usually starts 1 to 4 months after delivery. Signs include anxiety, insomnia, a fast heart rate, fatigue, weight loss and irritability, which are easy to blame on a new baby. Most women are diagnosed in the underactive phase, which typically starts 4 to 8 months after delivery.

In that phase, the ATA lists dry skin alongside fatigue, weight gain, constipation and depression. Most women's thyroid returns to normal within 12 to 18 months of symptoms starting, but about 20% in the underactive phase stay that way. Your risk is higher with type 1 diabetes, a past thyroid problem or thyroid disease in the family.

When Skin Changes Come With Low Mood

The National Institute of Mental Health (NIMH) says baby blues are mild and pass within the first 2 weeks after giving birth. Mood changes that are severe or last longer than 2 weeks after childbirth may be postpartum depression.

NIMH lists signs including a sad, anxious or "empty" mood most of the day, nearly every day, for at least 2 weeks. Others are hopelessness, guilt, losing interest in things, trouble sleeping even when the baby sleeps, and trouble bonding with your baby. Most episodes begin within 4 to 8 weeks of birth. Postpartum anxiety vs depression explains how anxiety can look different.

If any of this sounds familiar, see a doctor. In the US, the National Maternal Mental Health Hotline is free and confidential, 24/7, in English and Spanish. Call or text 1-833-852-6262 (1-833-TLC-MAMA).

Seeing or hearing things that aren't there, believing things that aren't true, feeling unusually high or confused, or feeling paranoid can be postpartum psychosis. NIMH calls this a psychiatric emergency: call 911 or go to the nearest ER.

If you're thinking about harming yourself or your baby, get help now. In the US, call or text 988 for the 988 Suicide & Crisis Lifeline. In Canada, call or text 988 for the 9-8-8 Suicide Crisis Helpline.

If your life is at risk or you can't keep yourself safe, call 911 or go to the nearest ER. In the UK, call Samaritans free on 116 123, any time, or 999 in an emergency. Elsewhere, call your local emergency number.

When Should You See a Doctor About Postpartum Skin?

See a dermatologist if melasma bothers you or isn't fading. Mayo Clinic suggests seeing a doctor if stretch marks cover large areas of your body.

See a doctor sooner for a new rash, severe itching or acne that doesn't respond to over-the-counter care. Ask about your thyroid if dry skin comes with tiredness, weight gain or low mood 4 to 8 months after birth. The postpartum recovery guide lists the body symptoms that need urgent care.

Frequently Asked Questions

How Long Does It Take for Skin to Go Back to Normal After Pregnancy?

Pigment changes such as the belly line usually fade within a few months. Melasma often fades after birth but can last years. Stretch marks fade and flatten, but they may never disappear completely.

Can I Use Retinol While Breastfeeding?

LactMed's entry is for prescription tretinoin, not over-the-counter retinol. It rates tretinoin cream low risk if you keep it off the nipple, areola and anywhere your baby touches. The AAD still says to check with your doctor first, since some ingredients, such as retinol, can harm your baby.

Will Melasma Come Back With Another Pregnancy?

It can. The 2023 American Family Physician review says melasma can return with later pregnancies and with birth control pills. Daily sunscreen helps keep it from darkening again.
