Hi, Such type of vaginal dryness is certain hormonal deficiency, menopause. Certain infections can cause this. I feel you should get examined by your gynecologist, followed by pathology testing for labia swelling and probable infection and estrogen hormone estimation. Thus, pin pointing the cause you would be given specific treatment of cause (either antibiotic for infection or hormone replacement creams or modules which act like hormone when taken orally. These are treatments apart from home remedies you have tried. Your doctor would select and prescribe them. Take care. Hope I have answered your question. Let me know if I can assist you further.
