Radiotherapy is one of the most frequently used methods in cancer treatment, and approximately sixty percent of patients undergo radiotherapy at some point during their treatment course. While high-energy radiation beams destroy tumour cells, they also damage the healthy skin cells in the treatment area. In 2026, innovative approaches to post-radiotherapy skin care are significantly improving patients' recovery processes.
Effects of Radiotherapy on the Skin
Radiation damage to the skin is classified into two categories: acute and chronic.
Acute Effects
These are effects that appear during treatment and in the first weeks following it:
- Radiation dermatitis: Redness, oedema, and tenderness in the treatment area
- Dry desquamation: Dryness and flaking of the skin
- Moist desquamation: In advanced cases, weeping open areas on the skin
- Burn-like reactions: Painful and tender skin areas
Chronic Effects
These are permanent changes that may appear months or years after treatment:
- Fibrosis: Hardening and thickening of the subcutaneous tissue
- Telangiectasia: Permanent dilation of fine superficial blood vessels
- Atrophy: Thinning and increased fragility of the skin
- Permanent pigmentation changes: Darker or lighter colour differences in the treatment area
- Lymphoedema: Swelling due to impaired lymphatic drainage
Acute Phase Care
The period during radiotherapy and the first 4–6 weeks following its completion is considered the acute phase. During this time the skin is extremely sensitive, and soothing and protective care is paramount.
Fragrance-free, preservative-free moisturisers should be applied to the treatment area. Aloe vera-based gels and thermal water sprays provide a soothing effect. Adhesive bandages or plasters should not be applied to the treatment area, and tight clothing should be avoided. When washing, the relevant area should be cleansed gently and never scrubbed.
Skin Renewal in the Chronic Phase
Once the acute phase has passed and the oncologist's approval has been obtained, a skin renewal programme can begin. The leading methods in this area in 2026 are as follows:
Fractional Laser Treatment
Fractional laser is an effective option for treating post-radiotherapy fibrosis and scar tissue. It stimulates new collagen synthesis by creating micro-channels in the skin. Application at low energy levels with extended intervals between sessions is recommended for this patient group. Please contact us for pricing information.
PRP and Mesotherapy
PRP therapy offers promising results in the repair of radiation-damaged skin. Platelet-rich plasma obtained from the patient's own blood accelerates tissue regeneration through growth factors. When combined with mesotherapy, hyaluronic acid and vitamins are delivered directly to the damaged area. Please contact us for pricing information.
Hyperbaric Oxygen Therapy
In chronic radiation damage, hyperbaric oxygen therapy supports wound healing by increasing tissue oxygen levels and promotes the formation of new blood vessels. It is considered a complementary method particularly in the treatment of fibrosis and chronic wounds.
Daily Care Recommendations
A daily care routine is of great importance for long-term skin health after radiotherapy. Moisturisers containing ceramides and niacinamide strengthen the skin barrier. The area that received radiation must be protected from sunlight for life. Antioxidant serums — particularly those containing vitamin C and vitamin E — provide additional protection against free radical damage.
Expert Follow-Up
Post-radiotherapy skin care and aesthetic interventions must always be carried out with a multidisciplinary approach. Close collaboration between the oncologist, dermatologist, and aesthetic specialist guarantees the safest outcomes. At Virtuana Clinic, we create individual assessments and personalised treatment plans within our post-radiotherapy skin renewal programmes.
