A balm does not contain water, so has no preservatives or alcohol which may cause stinging on broken, raw and inflamed skin. Whan the skin is in that condition, it is generally more sensitive and reactive. A balm is also better suited for skin that needs intensive treatment with actives as it sits on the skin for longer and allows better penetration of actives. It also contain waxes such as beeswax or candelilla wax (plant version of beeswax) which will increase hydration of the skin by preventing moisture loss from the skin's surface. It acts as a natural barrier when the skin is broken and compromised. It may feel oiler on the face, so a serum or cream would be better for the face.
