Brief summary: The study cream is to be evaluated in a multicenter, randomized, controlled clinical study carried out in 2 hospitals, in the Radiation Oncology service of Valencia to evaluate its radioprotective and radiomitigation effect in the prophylactic treatment of acute radiodermatitis caused by radiation.

A total of 82 patients with squamous cell carcinoma of the head and neck (SCCHN) were are going to be randomized in a study. Patients receive the study topical cream or "standard" skin care from Hospitals where the study is carried out. All patients will be treated with a combination of fractionated radiotherapy and platinum-based chemotherapy OR cetuximab for curative purposes.

The main objective of the study cream is to obtain a reduction in the number of patients who experience acute radiation dermatitis grade 3 or 4 (NCI CTCAE version 4.03) to grade 2, the last day of treatment. As a secondary objective, to obtain a reduction in the number of patients experiencing grade 3 or 4 to grade 0 acute radiation dermatitis, within a month of finish treatment. All patients will be evaluated periodically. The skin is photographed irradiated and all changes of radiation dermatitis are classified. The valuation of the radiodermatitis will be carried out objectively using a thermograph. In addition, the patients who complete questionnaires about their quality of life (QLQ-C30). These Questionnaires are answered in weeks 1, 2, 3 and 4 of treatment, as well as at the end of the radiation therapy or chemotherapy.

For the primary endpoint of radiodermatitis with CTCAE ≥ grade 2, assessments are made according to the protocol (PP), in addition to the primary intention-to-treat (ITT) approach. In this PP analysis, the patients are excluded according to protocol definition or meeting decisions preanalysis, respectively. The study is designed as a randomized trial with a 1:1 allocation to the two groups.

The secondary objective is to study a reduction in the percentage of patients experiencing radiation dermatitis with a maximum CTCAE grade 3 or 4 during the period of treatment and in the follow-up period of one month, thanks to the application of the cream of study.

Detailed description: The study will be a randomized, controlled, parallel, prospective, double-blind, two-armed clinical study with a cosmeceutical product.

The creams (experimental cream (CE) and standard of care (SC)) will be randomly distributed among the patients, so that 50% receive CE and the other 50% SC. Each tube will have a number whose content does not neither the evaluators and the patients will know.

In a period between January 2023 and June 2023, the radiation oncology services of Hospitals La Fe and Clinic de Valencia conducted a study on 82 patients with SCCHN. what will they be undergoing external beam radiotherapy with or without concomitant chemotherapy.

Radiotherapy treatment uses techniques of modulated intensity of the radiation beam (IMRT or VMAT) image-guided (IGRT) that offer very high precision in the daily administration of treatment, improving the tolerance of healthy tissues and the quality life of patients.

Patients will be divided into two groups:

Group A (intervention, CE): this group will receive the topical application of the study cream.

Group B (control, SC): standard care will be applied to this group.

Eligibility criteria: Inclusion Criteria:
