Laser Hair Removal During Pregnancy: What to Know and Do
Clinically Reviewed by: Angelica McWilliams, Licensed Advanced Esthetician
Pause laser hair removal while you are pregnant. No one has shown that it harms a baby. The reason is that no one has shown it is safe either, and the treatment is elective, so there is nothing to gain by taking the chance. Breastfeeding is a different story: the evidence we found points to no problem, and most people can book again after delivery. The rest of this guide covers why, what to use in the meantime, what to do if you had a session before you knew you were pregnant, and how to restart.
TL;DR
- Laser hair removal is not proven safe in pregnancy. Pregnancy-specific safety studies are missing, so the standard advice is to wait.
- Hormones can make skin more sensitive, so a treatment that used to feel fine may sting more and carry a higher risk of burns or dark marks.
- If you had a session before you knew you were pregnant, there is no evidence of harm. Tell your OB or midwife and pause future sessions.
- Shaving, trimming and gentle sugaring or waxing are the usual stopgaps. Skip bleaching and, for the belly, electrolysis.
- Breastfeeding is not a known reason to delay. Postpartum, book a consultation and start again.

What the evidence says about lasers and pregnancy
Lasers are not banned from pregnancy medicine. Doctors use them for certain medical conditions, and the research reflects that. A 2017 review of cosmetic procedures in pregnancy and lactation described the safety of these procedures as a complex question surrounded by uncertainty. The authors set out to consolidate what data exist, and for cosmetic lasers the data are thin.
A systematic review of elective laser therapy during pregnancy looked at the same gap from another angle. Much of what is published on lasers in pregnant patients covers medically needed treatment, not cosmetic work. That difference matters. When a laser treats a condition that needs care, the benefit can outweigh an unknown risk. When it removes hair you could shave, the balance tips the other way.
The American Pregnancy Association explains the mechanism: a laser targets the dark pigment in the hair and damages the follicle with heat or mechanical energy. It also states that no studies evaluate the safety of laser hair removal in pregnancy. Healthline summarizes the 2017 review the same way: lasers have been used for conditions such as kidney stones and genital warts in pregnant patients, but there is no safety data to support using them for cosmetic purposes.
So what you will read from most clinics and doctors is a precaution, not a warning about a proven danger. The light from a hair removal laser is aimed at the skin and follicles, not at the womb. But “unlikely to reach the baby” is a theory. In medicine, if a treatment is optional, the usual answer to a theory is to wait nine months.
Why skin changes make it a poor time anyway
Even setting the baby aside, pregnancy is a hard time to laser your skin.
Sensitivity. Hormonal changes can make skin more reactive. A treatment that was a mild snap before pregnancy may feel like a burning sting. Heightened sensitivity also raises the risk of burns and of hyperpigmentation or scarring after treatment.
Pigment. Many people notice darker patches during pregnancy, on the face and along the midline of the belly. Laser hair removal works by being drawn to pigment, so the settings a provider would normally choose are harder to get right on skin that is changing week to week.
Results. Healthline notes that treatment is less likely to work while you are pregnant, because of estrogen-driven hair growth, and the point of laser is permanent reduction. Hair that is in a hormone-driven growth phase can be gone or thinner after delivery, and you do not want to pay for sessions timed to hair that will change on its own.
Comfort and access. As the belly grows, lying in the positions needed for underarm, bikini or leg treatment becomes awkward. Not an issue for safety, but it is part of why most patients are happy to pause.
Pregnancy changes more than your skin. If you are working through the other changes, our partner-free reading list can wait, but one example is how gums react: bleeding gums during pregnancy is a common thing to raise with your dental team, and a good reminder that elective cosmetic work and necessary care are judged differently.
What the medical bodies say
The American College of Obstetricians and Gynecologists treats the patient’s safety as the first consideration, and its guidance on aesthetic services is about the role of the ob-gyn in aesthetic care. In practice, the position clinicians draw from this is that cosmetic procedures with no medical necessity should be avoided during pregnancy, because the risk and benefit do not favor intervening.
The Bump puts the situation plainly for readers: there is little data on whether laser hair removal in pregnancy is safe, and it frames what ob-gyns want you to know so you can make an informed choice. Your own OB or midwife knows your history, so they are the person to ask if you are on the fence.
We will tell you what we tell anyone who asks us: we do not treat clients who are pregnant. If you are not sure whether you might be, say so at your consultation.
What to do if you had laser before you knew you were pregnant
This is one of the most common worries, and the honest answer is reassuring but not absolute.
- Stop further sessions. Cancel or postpone anything on the calendar.
- Tell your OB or midwife. Mention the date, the area treated and, if you know it, the type of laser. They can note it in your record and answer questions about your specific case.
- Do not panic. There is no evidence that a session before you knew harmed a pregnancy. Evidence of safety is missing, but so is evidence of harm.
- Tell your provider. Let the clinic know so they can update your file.
- Care for the skin. Treat the area gently and follow the aftercare steps for laser hair removal while it heals. If it blisters, darkens or looks infected, see your health care provider.
Also worth knowing: laser hair removal is a series of treatments, so one session in early pregnancy is a very different exposure from a full course. Whatever the case, the plan is the same: pause and talk to your doctor.
Safer ways to manage hair while you wait
Hair can get thicker or more noticeable in pregnancy, and you are allowed to deal with it. Here is how the usual options stack up, based on what pregnancy resources say.
| Method | Pregnancy notes |
|---|---|
| Shaving | The simplest stopgap. Healthline lists shaving among temporary methods generally considered safe. Mind your balance as the belly grows. |
| Trimming | Gentle and low risk, good for the bikini line. |
| Tweezing and threading | Generally considered safe, best for brows and small areas. |
| Waxing and sugaring | Generally considered safe, though skin can be more sensitive, so test a small patch first. |
| Depilatory creams | Many practitioners prefer to avoid them because skin is more reactive, and a patch test is wise. |
| Bleaching | Best avoided during pregnancy. |
| Electrolysis | Many practitioners advise avoiding it in later pregnancy, especially on the abdomen, because of a theoretical concern about galvanic current. |
The ACOG guide to pubic hair care is a good plain-language read on the downsides of each method. It describes laser hair removal as the most expensive option and one needing several sessions with a licensed professional, which is useful context for deciding when to start the series.
If you want to compare the long game, our post on laser hair removal vs waxing lays out the trade-offs, which is helpful reading while you are in the shave-and-wait phase.
Breastfeeding and laser hair removal
This is the question many people really want answered. The MotherSafe guidance on skin, hair and cosmetic treatments in pregnancy and breastfeeding, from a New South Wales hospital service, is the source we leaned on. The research we reviewed found no evidence that laser hair removal affects breastfeeding or the quality of breast milk, and most professionals consider it fine to resume while nursing.
A few practical points for nursing clients:
- Avoid numbing creams without asking. If you want to use a topical anesthetic, check with your pediatrician or lactation consultant first, especially on large areas.
- Chest and nipple area. Be upfront with your provider about the area you want treated. Many people prefer to leave that zone alone while nursing, and that is a reasonable call.
- Hormones are still moving. Postpartum hormonal shifts affect hair growth, and some people see shedding for months after delivery. Your provider may suggest waiting until hair growth settles so you can see the true pattern.
- Sensitivity. Skin can be more reactive for a while after birth, so a patch test is a good idea.
If your doctor has told you to hold off for a medical reason, follow that advice over general guidance.
When to restart after delivery
There is no single date that fits everyone. Most people wait until they have been cleared at their postpartum checkup and feel ready to be on a treatment table. Here is a sensible approach.
- Wait for your postpartum clearance. Get the okay from your OB or midwife, especially after a cesarean if you want the lower abdomen treated.
- Give hormones time. If you are shedding, you may not have your usual growth pattern yet.
- Book a consultation. Tell us about your delivery date, whether you are nursing and any medications.
- Do a patch test. It is a quick way to see how your skin reacts.
- Plan the series. Our maintenance and timeline guide explains how sessions are spaced and what to expect over time.
Before your first appointment, our article on how to prepare for laser hair removal covers shaving, sun exposure and what to skip in the days before. If you wonder about comfort after a long break, what laser hair removal feels like by area is a useful guide.
Our perspective at Laser Skin Solutions
We see the same pattern again and again. A client is excited about a laser series, learns she is expecting and asks whether she can fit in one last session. Our answer is always the same, and it is not a hard one to give: there is no benefit that outweighs not knowing.
Our treatments use medical-grade technology and are delivered by licensed medical staff, and we build personalized plans around each person’s skin, hair and goals. That is exactly why we do not treat during pregnancy. A plan only works if the skin in front of us is stable and the person in front of us is safe. Pregnancy changes both, and the research does not give us the green light.
We also see the other side. Clients who waited are rarely sorry. They come back after delivery, we do a free consultation, we talk through hormones, nursing and timing, and we build a plan that fits a life with a newborn. In the Pacific Northwest, we also adapt protocols to the climate and the way skin changes through our gray, wet months and bright summers, which matters for sun exposure and aftercare.
Our advice: use the months of pregnancy to shave or trim, enjoy the break from appointments and plan for later. If you are curious, come in for a no-pressure chat, even before your due date, so there is a plan waiting for you.

FAQ
Is laser hair removal safe during pregnancy?
It has not been proven safe, and it has not been proven harmful. Because no pregnancy-specific safety studies exist and the treatment is elective, doctors and clinics advise waiting until after delivery. Ask your OB or midwife about your own situation.
Can I have laser hair removal while breastfeeding?
The sources we reviewed found no evidence that it affects breastfeeding or milk quality, and most professionals consider it fine to resume. Skip numbing creams unless your pediatrician or lactation consultant approves, and tell your provider if you want the chest area treated.
What if I had laser hair removal before I knew I was pregnant?
There is no evidence that an early session caused harm. Stop further treatments, tell your OB or midwife the date and area treated, and let the clinic know. If the skin blisters or looks infected, see your health care provider.
What is the safest way to remove hair while pregnant?
Shaving, trimming, tweezing and threading are generally considered safe, and gentle waxing or sugaring is fine for many people after a patch test. Avoid bleaching, and ask your doctor before using depilatory creams. Electrolysis is best avoided on the abdomen.
How long after birth can I restart laser hair removal?
There is no universal date. Most people wait for their postpartum checkup and let hormones settle, then book a consultation. A provider can plan around your delivery, nursing and skin.
