If you’re going through cancer treatment, your skin is probably not behaving like it used to. Chemotherapy, radiotherapy, surgery and hormone therapies all affect the skin in different ways, and most of the advice available online is either too vague to be useful or written by people who haven’t had to think hard about which ingredients actually matter when a skin barrier is compromised. We wanted a straight answer for our own range rather than an assumption, so we asked the Amethyst Trust, the organisation that trains UK spa and salon therapists to work safely with people living with and beyond cancer, to independently screen every ingredient we use. What we found was largely reassuring, with a couple of things we’re being upfront about below.
What treatment actually does to skin
Chemotherapy commonly leaves skin drier, thinner and more reactive than before, with a duller tone and occasional flushing or rash. Some drugs, capecitabine in particular, can cause hand-foot syndrome: redness, tenderness, cracking or peeling on the palms and soles. Nails can also change, becoming ridged, discoloured or lifting slightly from the nail bed.
Radiotherapy affects the skin in the treated area specifically. A reaction usually starts around ten days into treatment, can worsen for another week or two, and then settles, though the skin in that area stays more sun-sensitive for months afterwards. Surgery leaves a scar that needs time and the right care to settle and soften. Hormone therapies, common after breast and some other cancers, tend to dry the skin out generally, in the way lower oestrogen does at menopause.
None of this reflects anything you’re doing wrong. It’s the treatment doing its job elsewhere in the body, and the skin barrier bearing some of the cost.
Ingredients worth being cautious of
Most of what came back from the Amethyst Trust review falls into “worth knowing,” not “avoid at all costs,” and the ingredients below fall into a few clear groups.
Fragrance and essential oil components. A generic parfum or fragrance listing can hide dozens of individual components, occasionally including synthetic musks with a possible cancer link, so a disclosed scent or a fragrance-free product is the safer choice. Beyond that, a long list of naturally occurring fragrance components are recognised, well-studied contact allergens: linalool, limonene, citral, geraniol, eugenol, citronellol, cinnamyl and cinnamal alcohol, benzyl alcohol and benzyl salicylate, clove bud and leaf oil, peppermint oil and menthol, sandalwood oil, palmarosa and citronella oil, and rose extract, oil and water. All of these are entirely normal in botanical skincare and most people tolerate them without any issue. They’re worth knowing about specifically if your skin has become more reactive during treatment.
Ingredients that can increase sun sensitivity. The drying kind of alcohol (not the fatty, emollient kind like cetyl or stearyl alcohol), vitamin C esters like ascorbyl palmitate, carrot oil, citric acid, citrus peel oils, lactic acid, retinyl palmitate and turmeric root extract can all mildly increase how reactive skin is to UV. Worth an SPF regardless, but more so if you’re using any of these.
Phytoestrogen-rich plant extracts. Borage seed oil, evening primrose oil, prickly pear extract, peony root extract, geranium oil, lavender, palmarosa oil, turmeric and cranberry all have a chemical structure similar to oestrogen. The evidence on whether this matters in skincare, as opposed to diet, is genuinely unsettled, and we’ve written more on this below given how often it comes up for hormone-sensitive cancers specifically.
Preservatives and functional ingredients. Butylene glycol, phenoxyethanol, potassium sorbate, sodium benzoate and similar preservatives appear in small, regulated amounts across cosmetics generally and are considered safe by the relevant safety bodies, but are included here because they can occasionally cause mild irritation in already-sensitised skin.
None of this is a reason to panic about anything you already own. It’s a reason to read labels, favour fragrance-free where you can, and check with your oncology nurse or pharmacist if you’re ever unsure.
Hormone-sensitive cancers, including uterine cancer, and phytoestrogens
This comes up a lot, particularly for anyone with a hormone-receptor-positive breast or uterine (endometrial) cancer, so it’s worth answering properly rather than in passing.
Phytoestrogens are plant compounds that structurally resemble oestrogen and can weakly interact with oestrogen receptors. Whether that matters for someone with a hormone-sensitive cancer is a genuinely open question. On diet specifically, some studies have found women with higher dietary phytoestrogen intake have a lower risk of endometrial cancer, while others have found no protective effect at all. Neither direction is settled science.
On skincare specifically, which is the more relevant question here, the picture is more reassuring. A prospective cohort study published in Environmental Health in 2019 looked at whether heavy use of skincare products, creaming the body up to twice daily through mid-life, was associated with breast or endometrial cancer risk. It found no increased risk of pre- or post-menopausal breast cancer, oestrogen-receptor-positive or -negative breast cancer, or endometrial cancer.
So the honest position is this: phytoestrogen-containing plant extracts appear in some of our products, and in skincare generally. The evidence on whether that matters for hormone-sensitive cancers is unsettled, and leans reassuring for topical use specifically, even though dietary evidence is mixed. If you have a hormone-receptor-positive cancer, it’s worth mentioning to your oncology team if you want a view tailored to you, but there’s no established basis to avoid these ingredients outright.
Ingredients that are genuinely good news
The same review flagged a small group of ingredients as specifically useful for skin affected by cancer treatment. Calendula is antifungal, anti-inflammatory and antibacterial, and is well used for soothing compromised skin. Cardiospermum, also known as balloon vine, is calming and antibacterial. Hibiscus and inula are both antioxidant and anti-inflammatory. Algae extract is hydrating and soothing, and traditionally used to calm the delicate skin around the eyes. Rosehip seed oil is antioxidant and tissue-regenerating, and genuinely useful for softening the appearance of scars. Spirulina is rich in antioxidant vitamins and supports hydration. Between them, several have a long history of traditional use for skin under stress, including during radiotherapy recovery. More reassuring still, the large majority of the ingredients we use across the range, checked one by one, came back with nothing to flag at all.
What the ingredient review actually found
To be straightforward about the limits of this: the review looked at ingredients, not finished products, and the Amethyst Trust does not endorse or recommend specific products for use during cancer treatment, ours included. Of everything we checked, only two ingredients came back with a possible cancer-risk flag. One is a contaminant risk from certain sulfates that we don’t use in any of our formulations. The other is an undisclosed fragrance blend in two of our rose-scented products, flagged because the exact composition wasn’t specified to the reviewer rather than because it’s confirmed to contain anything harmful, and we’re following up to get that clarified. Every other ingredient in the range came back clear of that flag.
Always check with your oncology team before introducing anything new to your skincare routine, particularly during active treatment.
A personal note from Georgie
I’m a trained therapist as well as a formulator, and I’ve always been keen to grow the spa side of this business properly rather than as an afterthought. That means not guessing when it comes to skin that’s under real strain. We don’t formulate by trend, we formulate by function, so when it came to a category as sensitive as this, we didn’t want to mark our own homework. Asking an outside expert to go through every ingredient, line by line, was the only honest way to do it.
Skincare for hands, feet, nails and scars
If you’re experiencing hand-foot syndrome, apply a thick, fragrance-free cream several times a day, wear loose socks and gloves overnight to lock in moisture, and avoid tight shoes. Keep nails short and clean, moisturise cuticles daily, and avoid gel manicures and nail hardeners during treatment. Once a surgical wound is fully closed, gently massaging moisturiser or oil into the scar most days helps keep it supple as it heals, and silicone gel or sheets are well evidenced for softening and flattening scars.
Touch matters for more than the scar itself. Many people going through cancer treatment miss ordinary physical contact, whether that’s a massage, a facial or simply having their hands held while someone looks after them, and that’s something a lot of standard spas aren’t trained to offer safely.
Working with the Amethyst Trust
The Amethyst Trust trains therapists across UK spas and salons to give massage and beauty treatments safely to people living with and beyond cancer, adapting technique around things like lymph node removal, ports, stomas and sensitised skin. It grew out of a charity founded in Gloucester in 2010 and has trained therapists nationally ever since, maintaining a directory of qualified practitioners. If you’re considering a spa treatment during or after cancer, look for a salon with Amethyst Trust or SATCC-trained therapists. It means someone has actually thought about your port, your scar and your skin before they lay a hand on you.

You’re still you
Skin changes during treatment are visible, and that can be hard on days when you’d rather not think about being unwell at all. But almost everything described here is temporary. Skin recovers. Nails grow out. Scars soften. A gentle routine and the right kind of care, whether that’s a cream on your hands or an hour with a properly trained therapist, is a genuine way of feeling like yourself again. If you develop a rash, a wound that isn’t healing, or anything that concerns you, always speak to your cancer doctor or specialist nurse rather than treating it yourself.

Frequently Asked Questions
What skincare is safe during chemotherapy?
Fragrance-free or simply-scented products, favouring barrier-supporting ingredients over strong actives. Check with your oncology team before introducing anything new, and be more cautious with retinoids and undisclosed fragrance blends.
What can I use for hand-foot syndrome?
A thick, fragrance-free moisturiser applied several times a day, worn under loose socks or gloves overnight. Tell your oncology team if skin cracks, blisters or becomes painful.
Does skin go back to normal after chemo?
Yes, for most people. Dryness, sensitivity and discolouration are usually temporary and improve within weeks to months of finishing treatment.
What cream is best for a mastectomy scar?
Any plain, fragrance-free moisturiser or oil, massaged in daily once the wound is fully closed. Silicone gel or sheets are well evidenced for softening and flattening scars.
Can I get a facial or massage during cancer treatment?
Yes, with a therapist trained specifically in cancer care, such as those trained by the Amethyst Trust. They know how to adapt treatment around surgery, ports and sensitised skin.
