Are sunbeds safe while breastfeeding?

The verdict

No, and the reasoning is different from every other page in this batch. This is not a case of a pregnancy restriction carrying over or lapsing. It is a case of an activity that no authority thinks anyone should be doing, whether or not they are feeding a baby.

UKHSA states the position: sunbeds emit ultraviolet radiation, there is no evidence to suggest any type of sunbed is less harmful than natural sun exposure, and UKHSA and the World Health Organization discourage the use of sunbeds for cosmetic tanning. WHO's own advice is to avoid the use of artificial tanning devices, noting that sunbed use increases the risk of developing skin cancers and that artificial tanning should never be considered as an option to achieve sufficient vitamin D status.

There is no lactation angle to weigh against that, because there is no lactation angle at all. The harm from a sunbed is delivered to your skin and your eyes, in the cubicle, at the time.

Why breastfeeding is not the question

It is worth being explicit about this, because the shape of the answer is unusual.

Ultraviolet radiation does not penetrate beyond the skin in any way that could reach milk. WHO describes the acute effects as DNA damage, sunburn, phototoxic and photoallergic reactions and suppression of the immune system, and the chronic effects as cutaneous melanoma, squamous cell carcinoma, basal cell carcinoma and premature skin ageing. Every one of those is local to the person exposed.

So no health authority publishes a breastfeeding-specific restriction on sunbeds, and the absence is not a gap in the guidance. It is a category error in the question. The relevant advice is the general advice, and the general advice is don't.

What the risk actually is

The Department of Health and Social Care sets out the current figures. The WHO's International Agency for Research on Cancer has classified UV radiation, and the use of sunbeds, as carcinogenic to humans. Recent research shows that those who have used sunbeds have a 27% higher risk of melanoma than those who have never used them, and using sunbeds before the age of 20 increases the risk of developing melanoma by approximately 47%.

The listed harms go beyond melanoma: squamous cell and basal cell carcinomas, ocular melanomas, actinic keratoses which are precancerous lesions that can progress to squamous cell carcinoma, serious eye damage including photokeratitis and cataracts, particularly without protective eyewear, sunburn, premature ageing through the breakdown of collagen and elastin, and the worsening or triggering of photosensitive skin conditions.

For scale, National Disease Registration Service data records 247,299 people in England diagnosed with skin cancer in 2023, including 18,000 new melanoma cases, with melanoma causing around 2,500 deaths in England each year.

How much is too little to matter

There is no safe dose to give, which is the honest answer. UKHSA states that there is no evidence any type of sunbed is less harmful than natural sun exposure, and the idea of a protective base tan has no support in any of this guidance.

UKHSA does give harm-reduction advice for adults who intend to use one anyway, and it is worth quoting accurately: if you are aged 18 or over and wish to use a sunbed, ask for guidance on the use of the sunbed, and limit your use. Do not have repeated sessions to build up a quick tan before a summer holiday. If you have very fair skin, burn easily in the sun or have had skin cancer, do not use a sunbed at all.

The other reason to be sceptical of a salon's reassurance is that the marketing is under active enforcement. In January 2026 the UK Advertising Standards Authority upheld five rulings against commercial sunbed advertisers for promoting safe tanning, with some adverts implying that sunbeds could help manage medical conditions by boosting vitamin D or easing eczema. A Melanoma Focus survey found that only 62% of participants knew sunbed use increases skin cancer risk, dropping to 52% among 18 to 25 year olds, and that 23% of 18 to 25 year olds believed sunbed use reduces cancer risk.

The law, and where it is going

Under the Sunbeds (Regulation) Act 2010 in England and Wales it is an offence to allow people aged 17 and under to use sunbeds on commercial premises, including beauty salons, leisure centres, gyms and hotels. Equivalent restrictions apply in Scotland under the Public Health etc. (Scotland) Act 2008 and in Northern Ireland under the Sunbeds Act (Northern Ireland) 2011. Northern Ireland, Scotland and Wales additionally require age verification, supervision and display of health risk information, and Northern Ireland and Wales require operators to supply protective eyewear.

England is consulting on catching up: mandatory ID checks, supervision of use, a ban on selling or hiring sunbeds to under-18s, mandatory health risk information, mandatory provision of protective eyewear, and a prohibition on businesses promoting unproven health benefits.

If you want the look anyway

Fake tan and spray tan are the alternative every authority points to, and they carry no UV exposure at all. They are topical products applied to intact skin, and no UK, Irish or US authority restricts them while breastfeeding.

The one product to avoid entirely is injectable tanning products, sometimes sold as melanotan. These are unlicensed injectable medicines sold illegally, and they belong in the same category as the unlicensed injectables the MHRA is currently prosecuting.

If your skin has changed since pregnancy, with new pigmentation or patches that have not faded, a sunbed is the worst possible response, because UV exposure worsens post-inflammatory and hormonal pigmentation. Take that to your GP.

Where guidance differs

It does not, in any respect that matters. UKHSA and NHS England both strongly advise against using sunbeds because of the increased risk of skin cancer and other harms from UV radiation. WHO discourages cosmetic sunbed use and recommends that no person under 18 should use one. IARC classifies both UV radiation and sunbed use as carcinogenic to humans. The FDA regulates sunlamp products as medical devices and requires warning labels. Australia went furthest, banning commercial solaria in every state and territory by 2016.

The only variation is in how hard each jurisdiction has legislated, and the direction of travel is one way. There is no country in which a public health authority recommends sunbeds, and none in which breastfeeding changes the answer, because breastfeeding was never part of the calculation.
