Can I Wipe Over Parts of the Skin Affected by Eczema in Wudu?

Question: I suffer from a skin condition called eczema around my mouth and nose. One of the things that makes it worse is washing the area with water. How do I deal with making wudhu in my situation? I have tried keeping my wudhu for at least 2 prayers but find it hard to do so. Would tayammum be valid for just this body part?
In the Name of Allah, Most Merciful and Compassionate,
Assalāmu ‘alaykum dear brother or sister in faith,
After applying a moisturizer or other occlusive substance to the affected areas of your skin, you may lightly wipe over them with a wet hand. [Shurunbulali, Nur al-Idah, 26]
Allah, Most High, says,  “And no hardship did He lay upon you in the Religion” [Quran 22:78]
