Red light therapy has been in use across clinics and wellness centres for years, but as more people see the benefits, it has become more widely available in salons and at-home formats. From boosting collagen and fibroblast production to stimulating hair growth and relieving pain, it is no wonder people are seeking out this treatment.
But is red light therapy safe to have while pregnant?
Whether you were using red light therapy regularly before conceiving or are simply curious about whether it is something you could start, this guide is here to give you a clear, honest answer.
What is Red Light Therapy?
Red light therapy (RLT), which is also known as photobiomodulation, is a treatment that uses specific wavelengths of low-level red and near-infrared light to stimulate the body’s cells. Unlike UV light, which can damage the skin, red light is considered non-ionising and works by being absorbed into the mitochondria, encouraging cells to produce more energy in the form of ATP.
This increased cellular activity can lead to a range of potential benefits, including:
- Reduced inflammation
- Improved skin health and collagen production
- Accelerated muscle recovery
- Better sleep quality
- Relief from pain and stiffness
At Concordia Clinic, we offer full-body red light therapy to support general well-being and accelerate recovery.
Red light therapy devices come in several forms, including full-body beds (like ours at the clinic), handheld panels, and LED face masks designed for home use. Each delivers light at slightly different intensities and wavelengths, which is worth keeping in mind when considering use during pregnancy.
Is Red Light Therapy the Same as UV Light?
This is one of the most common points of confusion, and it is worth addressing directly. Red light therapy and UV light are not the same thing.
UV light is most commonly used in sun and tanning beds but it can cause DNA damage to skin cells over time and is associated with increased skin cancer risk. That is precisely why it is avoided during pregnancy and in general.
Red light therapy operates at completely different wavelengths (typically 630–850nm) and does not contain UV rays. It does not cause the same cellular damage, does not trigger melanin production, and is not classified in the same risk category. The two are frequently confused because some RLT beds look visually similar to sunbeds, but the mechanism, the wavelengths, and the effects on the body are fundamentally different.
That said, the absence of UV risk does not automatically mean RLT is safe for use during pregnancy.
Is Red Light Therapy Safe During Pregnancy?
The short answer is: we do not yet know enough to say it’s safe.
That is not meant to alarm you. Red light therapy is well-tolerated at low levels and has a good safety profile in the general population. The issue during pregnancy is not that RLT has been shown to be harmful, but that there is currently a lack of research specifically examining how red light therapy affects a developing foetus.
Because of this gap in the evidence, many healthcare professionals, clinics, and RLT device manufacturers apply the precautionary principle: in the absence of sufficient data, it is better to avoid unnecessary exposure during pregnancy. The NHS advises that not all complementary therapies are safe during pregnancy and that patients should always consult their midwife, GP, or pharmacist before using them.
Two types of light are used in RLT, and they behave differently in the body:
- Visible red light (typically 630–670nm) penetrates the surface layers of the skin, primarily targeting skin tissue.
- Near-infrared light (typically 810–850nm) penetrates significantly deeper, reaching muscle, bone, and potentially internal organs.
Near-infrared wavelengths are the subject of most caution, given their deeper penetration and the theoretical (if unproven) concern about exposure to developing foetal tissue. There is also a consideration that RLT may trigger an inflammatory response in skin that is already sensitive due to pregnancy hormones.
Until more robust research is available, the responsible position is to advise against red light therapy during pregnancy.
What Are the Potential Benefits of Red Light Therapy During Pregnancy?
Some practitioners and researchers point to potential benefits of RLT that could, in theory, be relevant during pregnancy.
Pregnancy brings a range of physical changes that RLT is commonly used to address in the general population: back pain, joint discomfort, skin changes such as acne and stretch marks, fatigue, and mood changes.
- Skin health: RLT stimulates collagen and elastin production, which may help with the skin stretching that occurs during pregnancy and could potentially reduce the severity of stretch marks. It may also help calm hormonal breakouts without the need for topical treatments that are restricted during pregnancy.
- Pain relief: RLT has established evidence for reducing musculoskeletal pain and inflammation. For pregnancy-related back pain, hip discomfort, and conditions such as carpal tunnel syndrome and arthritis, it is theoretically applicable, though studies specifically in pregnant women have not yet been conducted.
- Mood support: Red light therapy can support mood and reduce symptoms of depression in the general population, with research suggesting it influences serotonin production and circadian rhythm regulation. While studies specifically in pregnant women are limited, light therapy more broadly has been explored as a low-risk alternative to antidepressants during pregnancy.
- Placental health: Some early research suggests whether specific wavelengths of red light on placental function can have a protective effect. This research is preliminary and should not be used as a basis for self-treating, but it forms part of the broader picture.
These potential benefits are worth knowing about, but they do not change our clinical position. The lack of large-scale, controlled trials in pregnant populations means caution remains the appropriate stance. If you are experiencing any of the above symptoms, we would always recommend discussing evidence-based options with your midwife or GP before considering RLT.
Can You Use Red Light Therapy on Your Face While Pregnant?
Facial skin changes are extremely common during pregnancy. Hormonal shifts can trigger acne, increased sensitivity, pigmentation changes such as melasma, and general changes in skin texture. Understandably, many women turn to red light therapy as a potential solution.
Facial RLT devices like whether wands, panels, or LED masks, operate at lower intensities than full-body systems, and the depth of penetration from a facial device is generally limited to the skin’s surface and underlying layers. On that basis, some people reason that facial use carries lower risk.
There are, however, a few important considerations:
Eye safety
The eyes are particularly sensitive to light exposure, and near-infrared wavelengths are invisible to the naked eye, meaning you would not naturally blink or look away. Most devices come with protective goggles for this reason, but this remains a meaningful risk factor during pregnancy.
Heat generation
Some LED devices produce a degree of localised warmth. Elevated temperatures (even mild and localised ones) are generally something to be cautious about during pregnancy, as the body’s thermal regulation is already under greater demand.
Device guidance
The majority of reputable facial RLT brands include pregnancy as a contraindication in their product guidelines. If the manufacturer advises against use during pregnancy, that guidance should be taken seriously.
Red light therapy masks during pregnancy
LED face masks have become increasingly popular in recent years, with devices from brands like CurrentBody, Déesse Pro, and Dr. Dennis Gross finding their way into home skincare routines. If you have one at home and are now pregnant, it is natural to wonder whether it is still safe to use.
The guidance here follows the same principles as facial RLT more broadly. And, if anything, masks present a few additional considerations:
- Full-face coverage means a greater surface area of light exposure concentrated around the head, including close proximity to the eyes, sinuses, and neck.
- Prolonged contact with the face, often in a sealed or close-fitting design, can increase localised warmth.
- Most mask brands explicitly advise against use during pregnancy. If you check the safety information for your specific device, you are likely to find pregnancy listed as a contraindication.
If you are currently mid-course with a face mask treatment plan, the sensible approach is to pause until after pregnancy and, ideally, until you have finished breastfeeding. The good news is that red light therapy is not a time-sensitive treatment in most cases, and picking up where you left off postpartum will still deliver the benefits you are looking for.
Our recommendation is to pause facial red light therapy for the duration of pregnancy and to speak with your healthcare provider about managing any skin changes in the meantime.
Can You Do Red Light Therapy While Pregnant? A Trimester-by-Trimester View
While the overall guidance remains cautious throughout pregnancy, it is helpful to understand why caution varies across the different stages.
First Trimester
The first trimester is the period of greatest developmental sensitivity. This is when the major organ systems form, cell division is most rapid, and the embryo is at its most vulnerable to any external disruption. Weeks one to twelve are widely considered the highest-risk window for any complementary therapy, and red light therapy is no exception.
It is also worth noting that many women do not yet know they are pregnant during the early weeks, creating another reason to pause RLT if there is any possibility of pregnancy.
Our advice: avoid red light therapy entirely during the first trimester.
Second Trimester
By the second trimester, many of the most critical developmental stages are complete, and some healthcare practitioners take a more flexible approach during this window. However, there remains no clinical consensus on the safety of RLT at any stage of pregnancy. Your individual circumstances, including your health, the device type, the duration of exposure, and the wavelengths involved, all play a role.
Our advice: do not resume red light therapy without explicit guidance from your healthcare provider.
Third Trimester
The third trimester brings its own set of physical changes, like increased skin sensitivity, greater circulatory demands, and a higher susceptibility to overheating. Full-body red light therapy in particular generates warmth through cellular stimulation, and elevated body temperature is something to be managed carefully in late pregnancy.
Our advice: continue to avoid red light therapy during the third trimester. The postpartum period is not far away, and it is well worth waiting.
Postpartum
The good news is that red light therapy is generally considered safe to resume after pregnancy, once you are no longer breastfeeding or have confirmed with your healthcare provider that it is appropriate. Many women find it a useful part of their postpartum recovery as it supports skin health, reduces inflammation, and helps with energy levels during what can be a physically demanding time.
Pregnancy-Safe Alternatives to Red Light Therapy
If red light therapy has been part of your routine for skin health, recovery, or general well-being, there are plenty of evidence-backed alternatives that are considered safe during pregnancy.
For skin health
Hormonal skin changes during pregnancy can be frustrating, but several pregnancy-safe ingredients may help.
- Azelaic acid is one of the better-studied options for managing acne and pigmentation.
- Vitamin C can support brightness and collagen.
- Niacinamide is well-tolerated and helpful for redness and uneven texture.
- A broad-spectrum SPF is also essential, particularly for managing melasma.
Always check any skincare product with your midwife or dermatologist before use.
For muscle recovery and pain relief
If you have been using red light therapy to manage pain or support muscle recovery, prenatal massage may be a suitable alternative. Our deep tissue massage, sports massage, and having acupuncture during pregnancy can address back and pelvic pain. Always let your practitioner know you are pregnant before any session.
For Swelling and Fluid Retention
Swelling in the legs, ankles, and feet is a common complaint, particularly in the second and third trimesters. Lymphatic drainage massage is a gentle technique that encourages fluid movement and can help ease this discomfort.
For mood and energy
If you have been using RLT for its mood-supporting or energy-boosting effects, it is worth speaking to your GP about general well-being support during pregnancy. Vitamin D levels, sleep quality, and gentle movement all play a significant role in how you feel day to day.
Should You Use Red Light Therapy While Pregnant?
So, can you use red light therapy while pregnant? The evidence-based answer is that most healthcare professionals currently advise against it, not because RLT has been proven harmful during pregnancy, but because there is insufficient research to confirm that it is safe.
The same applies whether you are asking about a full-body panel, facial treatments, or an at-home LED mask. The depth of penetration, device strength, and wavelengths involved all vary, but the principle remains the same. When in doubt during pregnancy, the precautionary approach is the right one.
This is consistent with broader NHS guidance, which advises that data on the safety of complementary therapies in pregnancy is limited, and that patients should always speak to their midwife or GP before using them.
If you would like to explore what treatments might be appropriate during or after your pregnancy, our team at Concordia Clinic is happy to help. We will always point you in the right direction and work alongside your existing maternity care where needed.

Frequently Asked Questions
Can you use red light therapy while pregnant?
Most healthcare professionals advise against red light therapy during pregnancy due to a lack of research into its effects on fetal development. We recommend pausing treatment for the duration of your pregnancy and consulting your GP or midwife before resuming.
Is red light therapy safe in pregnancy?
There is currently insufficient clinical evidence to confirm that red light therapy is safe during pregnancy. Because of this, the precautionary principle applies, and most RLT providers, including Concordia Clinic, advise against use while pregnant.
Can I use red light therapy on my face while pregnant?
Facial red light therapy devices operate at lower intensities than full-body systems, but they still raise concerns during pregnancy, including eye safety and proximity to developing tissue. Most device brands list pregnancy as a contraindication. We advise pausing facial RLT during pregnancy.
When can I start red light therapy again after pregnancy?
Many women resume red light therapy after delivery, once they are no longer breastfeeding and have received clearance from their healthcare provider. Postpartum is often an excellent time to benefit from RLT’s anti-inflammatory and skin-supporting properties.
Are there any red light therapy treatments safe for pregnant women?
There is currently no specific trimester or device type that has been confirmed safe for use during pregnancy. Any decision about complementary therapy during pregnancy should be made in consultation with your midwife, GP, or obstetrician.
