Chemotherapy and modern cancer treatments can affect far more than cancer cells. Many patients experience changes to their skin, scalp, nails, and nerve sensations that can impact comfort, sleep, mobility, and quality of life.
This nurse-written guide explains the most common chemotherapy-related skin side effects, how they differ by cancer type and treatment approach, and how gentle, fragrance-free, ingredient-aware skin care can help support comfort during treatment.
Why Chemotherapy Affects the Skin
Chemotherapy, targeted therapy, and immunotherapy affect rapidly dividing cells. Skin cells, hair follicles, and nail beds regenerate quickly, which makes them more vulnerable to treatment effects.
Cancer treatments may:
- Weaken the skin barrier
- Increase inflammation
- Alter immune responses
- Increase sensitivity to friction, heat, and sunlight
The result can be dryness, rashes, peeling, pain, and changes in sensation.
Common Chemotherapy Skin Side Effects
Dry, Fragile, or Peeling Skin (Xerosis)
What patients experience:
Tightness after showering, flaking, itching without rash, cracked knuckles or heels, and skin that feels “paper thin.”
Oncology nursing tips:
• Bathe with lukewarm water only
• Use gentle, non-foaming cleansers
• Moisturize within 3 minutes of bathing
• Reapply moisturizer to hands after washing
Ingredient support nurses look for:
Aloe vera, botanical hyaluronic acid, glycerin, shea butter, jojoba oil, calendula, green tea, and panthenol help support hydration and the skin barrier without overstimulation
Hand-Foot Syndrome (Palmar-Plantar Erythrodysesthesia)
What patients experience:
Tingling, redness, swelling, burning, peeling, or cracking on palms and soles. Walking or gripping objects may become painful.
Oncology nursing tips:
- Treat early—do not wait for peeling
- Avoid heat, friction, and tight footwear
- Use thick barrier creams multiple times daily
- Cotton gloves or socks at night can help reduce friction
Comfort-support ingredients:
Aloe vera, shea butter, safflower oil, oat oil, calendula, and chamomile are commonly used to soften skin and calm irritation when applied consistently
Rashes From Chemotherapy, Targeted Therapy, and Immunotherapy
Rashes vary depending on treatment type.
Chemotherapy-related irritation:
Often appears as red, itchy, sensitive patches, especially where skin is dry or irritated.
Targeted therapy rashes (such as EGFR inhibitors):
May resemble acne but behave differently and should not be treated with traditional acne products.
Immunotherapy-related rashes:
Can be immune-mediated and may worsen quickly if not addressed early.
Oncology nursing tips:
- Avoid scrubs, exfoliants, or harsh actives
- Moisturize even when rash is present unless instructed otherwise
- Report rapidly spreading, painful, or blistering rashes immediately
Hair Loss, Dry Scalp, and Scalp Pain
What patients experience:
Tenderness, tightness, itching, flaking, or burning of the scalp—sometimes even before hair loss occurs.
Oncology nursing tips:
- Wash less often with lukewarm water
- Avoid scrubbing or aggressive brushing
- Moisturize the scalp gently
- Pat dry, never rub
Scalp-supportive ingredients:
Aloe vera, oat oil, oatstraw extract, calendula, chamomile, and cucumber extract help support comfort on sensitive or bald scalps
Nail and Cuticle Changes
What patients experience:
Brittle nails, ridging, discoloration, nail lifting, or painful cuticles that can increase infection risk.
Oncology nursing tips:
- Keep nails short
- Moisturize cuticles daily
- Avoid gel or acrylic nails during treatment
- Wear gloves for household chores
Neuropathy-Related Sensations Affecting Skin Comfort
Neuropathy is not a skin disease, but nerve changes can cause burning, tingling, or sensitivity in hands and feet that affects daily comfort.
Oncology nursing tips:
- Report symptoms early
- Protect hands and feet from temperature extremes
- Use sensory-support products only on intact skin
Sensory-support ingredients:
Menthol, camphor, ginger, arnica, and peppermint are used for cooling or warming sensations and should never be applied to broken skin
Skin Side Effects by Cancer Type & Treatment Pattern
Fragrance-Free vs Therapeutic Essential Oils: A Nursing Perspective
When oncology teams recommend “fragrance-free,” they are referring to synthetic fragrances added only for scent. These commonly cause irritation in compromised skin.
Therapeutic essential oils are different when:
- Used in very low concentrations
- Clearly listed on the ingredient label
- Included for a functional purpose (calming, soothing, sensory support)
For highly reactive patients, unscented options are often preferred. Choice and tolerance matter during treatment.
Simple Daily Skin Care Routine During Chemotherapy
Morning
- Gentle cleanse or rinse
- Apply moisturizer
- Sun protection as tolerated
Evening
- Lukewarm shower
- Full-body moisturization
- Thicker barrier care on hands and feet
All Day
- Reapply after washing
- Avoid friction and heat triggers
When to Call Your Oncology Team Immediately
- Blistering or peeling skin
- Fever with rash
- Rapidly spreading redness
- Open cracks with pain or drainage
- Nail swelling or infection
