Skincare during cancer treatment: a considered guide.

Cancer treatment can be physically and emotionally demanding, and the skin often carries some of that load. Chemotherapy, radiotherapy, immunotherapy and targeted therapies each affect the body differently, but many share one thing in common: they can make the skin drier, more sensitive and more reactive than usual. Understanding why this happens — and how a considered daily routine can help — is one of the small, empowering steps many patients take alongside their medical care.

Why the skin behaves differently during treatment

The outer layer of the skin, the epidermis, renews itself constantly. Many cancer treatments work by targeting rapidly dividing cells, so even though they are directed at cancer cells, they can also influence healthy tissues that renew quickly — the skin, hair follicles and mucous membranes among them. This is one of the reasons dryness, irritation and changes in texture are so commonly reported by patients undergoing chemotherapy, and why the skin over a radiotherapy field can become tender, warm or discoloured after several sessions.

Immunotherapy behaves differently. Because it engages the immune system, some patients notice rash-like eruptions, itching or patches of dryness as their body responds. Targeted therapies can bring their own specific patterns of skin change. In every case, your oncology and dermatology team are the definitive source of advice — and they may recommend adjusting your skincare, pausing certain products or introducing new ones as your treatment progresses.

The role of the skin barrier

The skin barrier is the thin, protective outer layer that keeps water in and irritants out. When it is intact, skin looks and feels comfortable. When it is stressed — by treatment, cold air, hot showers, harsh cleansers, or friction — water evaporates more quickly and small irritants penetrate more easily. This is often when tightness, flaking and reactivity begin. Supporting the barrier means using gentle, hydrating products consistently, and avoiding anything that could strip it further.

Skincare during chemotherapy

Many patients find that a minimalist, fragrance-free routine becomes their most reliable ally during chemotherapy. Cleanse gently with lukewarm water and a mild, non-foaming wash; moisturise while skin is still slightly damp; and reapply on the hands, elbows, shins and any area that feels dry throughout the day. Sun protection matters — chemotherapy can heighten sun sensitivity, so daily broad-spectrum SPF and physical protection (hats, long sleeves, shade) become part of the routine even in winter.

Chemotherapy-induced dry skin is one of the most common complaints, and it can appear anywhere on the body. The scalp may feel unusually dry, particularly during hair changes; the lips may crack more easily; and the hands and feet can become fragile. A minimal ingredient philosophy — few, well-chosen botanicals — often reduces the risk of unexpected reactions.

Skincare during radiation therapy

Radiotherapy is delivered to a specific area, so the skin over the treatment field is what typically requires the most care. Your radiation team will give you clear, up-to-date guidance — always follow it. In general, gentle cleansing, patting dry (never rubbing), and applying a bland, fragrance-free moisturiser are the pillars. Avoid perfumed products, strong active ingredients, adhesive dressings and anything that could increase friction over the area. If skin reactions develop, your team can advise on appropriate topical care.

Understanding hand-foot syndrome

Hand-foot syndrome — also known as palmar-plantar erythrodysesthesia — can occur with certain chemotherapy and targeted therapy drugs. It typically appears as redness, tenderness, tingling or peeling on the palms and soles. Because these are areas of the body under constant friction and pressure, proactive care can make a meaningful difference to comfort.

Practical steps often recommended by oncology nurses include avoiding hot water and prolonged heat, limiting friction (long walks, tight shoes, vigorous scrubbing), and applying a rich, fragrance-free balm to hands and feet several times a day. Cotton gloves or socks worn overnight over a generous layer of balm can help concentrate hydration where it is needed most. Report any new or worsening symptoms to your medical team promptly — they may adjust your dose or treatment schedule.

Ingredients: what to look for, what to avoid

Reactive skin is often better served by simpler formulas. Look for hydrators such as glycerin, humectant plant extracts and cold-pressed botanical oils. Emollients like shea butter, cocoa butter and apricot oil help skin feel supple. Antioxidants such as vitamin E round out a considered formulation.

Many patients feel more comfortable avoiding synthetic fragrance, high concentrations of essential oils, alcohol-heavy toners, strong acids, retinoids and mechanical exfoliants during treatment. Always confirm any additions or removals with your medical team, especially when treatments overlap.

Building a sustainable ritual

The best routine is one you can actually keep. During treatment, energy is precious. A three-step ritual — cleanse, moisturise, protect — is often enough. Keep products within easy reach: a balm on the bedside table, a body lotion by the shower, a lip balm in a pocket. Small acts of care, repeated, add up to meaningful comfort.

Endoca's oncology-oriented range was developed with this philosophy in mind: minimal ingredients, food-grade purity, organic botanicals, and formulas that respect the skin's own rhythms. It is cosmetic skincare — not medicine — but it is made with the seriousness that this moment in someone's life deserves.
