Hello,
The Sjögren's syndrome is an auto immune disorder with variety of clinical manifestations as 
dry skin, eyes, mouth etc. Apart from the systemic steroids, facial dryness can be dealt with:
- Fruit face pack wash
- Avoidance of rubbing the face
- Be very gentle to sponging
- Avoid prolong, excess sun exposure
- Local application of Multan mitti, 
aloe vera gel or 
calamine lotion as per the availability
- Healthy nutritious diet
- Supplemental multi vitamins, minerals, anti-oxidants with zinc, 
magnesium and 
vitamin A and E particularly
Take care. Hope I have answered your question. Let me know if I can assist you further.
