Contact Dermatitis

The goal of this clinical trial is to ensure that contact dermatitis is not prohibiting any person with diabetes the access to the optimal treatment. The main questions this study aims to answer are: 1. How many pediatric patients with contact dermatitis due to diabetes devices experience recurrence of contact dermatitis depending on which type of patch they use under their device. 2. Is one type of patch (silicone-based vs. hydrocolloid patch) better than the other at preventing contact dermatitis? The group being investigated is children and adolescents aged 2-18 years with contact dermatitis caused by either an insulin pump or a continuous glucose monitor. The participants will be asked to do different surveys on well-being and they will go to three physical visits. At the visits the the following will happen: * clinical skin examination * skin picture (of last used pump and sensor site as well as reportet skin reactions) * height and weight * blodsample (HbA1c and fillagrin mutations) * interview on skin reactions etc. * ultrasound of the skin * tape strips of the skin * EIS (transmit harmless electrical signal through the skin)

The goal of this clinical trial is to learn if a novel barrier topical product works to treat barrier dysfunction in adults. It will also learn about the safety of the novel barrier topical product. The main questions it aims to answer are: Does the novel barrier topical product improve skin hydration, skin sebum, redness, and pigmentation? Does it improve subjective dryness and itch? Researchers will compare the novel barrier topical product to petrolatum (a gold standard occlusive barrier repair agent) to see how they are comparable in treating skin barrier dysfunction. Participants will: Apply the novel barrier topical product or petrolatum twice a day for 28 days Visit the clinic once a week for checkups and tests Keep a diary of their application of the assigned product
