Chemotherapy is one of the most widely used cancer treatments, but in addition to targeting cancer cells, it also affects healthy rapidly-dividing cells — including those of the skin, hair, nails, and mucous membranes. As a result, many patients undergoing chemotherapy experience skin-related side effects that may affect comfort, appearance, and overall quality of life.

Timely recognition of symptoms, proper skincare, and support from a dermatologist can significantly improve how patients feel throughout treatment.

 

Common Skin-Related Symptoms and Changes

Rashes (papulopustular eruptions)

  • Red bumps and small pus-filled spots (papules and pustules)

  • Often appear on the face, scalp, chest, and upper back

  • May cause itching, burning, or discomfort

  • Often linked to immune system reactions

  • Management: gentle cleansing, moisturizing creams, avoid temperature extremes

Hand-Foot Syndrome

  • Redness, swelling, tingling, and burning in the palms and soles

  • In severe cases, skin may peel, crack, or form ulcers

  • Main treatment: pause chemotherapy, apply intensive moisturizers, protect skin

Itching (pruritus)

  • Can be acute (allergic reaction) or chronic (dry skin)

  • Management: moisturizers, antihistamines (prescribed by a doctor), hydration

Photosensitivity (sun sensitivity)

  • Higher risk of sunburns and rashes with sun exposure

  • Recommendations: avoid direct sun, wear protective clothing, use SPF 50+ sunscreen

Hyperpigmentation

  • Dark spots or discoloration, commonly on the face, hands, or nails

  • Usually fades after treatment

  • In some cases, oral medications may be needed to reduce itching

Mucositis (inflammation of mucous membranes)

  • Painful sores in the mouth

  • Can make eating and drinking difficult

  • May lead to dehydration or weight loss

  • Treatment: anti-inflammatory rinses, pain relief as needed

Hair Loss (Alopecia)

  • Affects hair in the anagen (growth) phase

  • Hair may thin or fall out in patches

  • Typically grows back within 3–6 months after treatment ends

  • Tips: gentle scalp care, avoid harsh hair products

Nail Changes (Paronychia)

  • Pain, redness, and swelling around the nails

  • May be caused by bacteria, fungi, or viruses due to immune suppression

  • Treatment depends on the cause; in rare cases, surgical help is needed

 

 

When to See a Doctor

Contact a doctor or dermatologist if you notice:

  • Painful or spreading rashes

  • Intense or persistent itching

  • Ulcers, cracking, or bleeding skin

  • Sudden or extensive hair or nail loss

  • Signs of infection (fever, pus, swelling)

 

Skincare Tips During Chemotherapy

  • Use gentle, fragrance-free cleansers

  • Moisturize the skin regularly with rich creams

  • Avoid hot showers, scrubbing, or exfoliating

  • Protect skin from cold, wind, and sun

  • Wear soft, breathable clothing

  • Drink plenty of water to stay hydrated from within

 

Conclusion

Skin changes during chemotherapy are common but usually temporary. With proper skincare, symptom management, and the guidance of a dermatologist, most side effects can be reduced or controlled. Early attention to skin problems helps patients feel more comfortable and maintain better quality of life during cancer treatment.
