Dry skin

I have extremely dry skin on my outer labia and my clitoral hood, it’s so itchy and irritating, help!!

I’ve tried coconut oil and non scented, sensitive lotion, neither have worked. My mom told me to try A&D; ointment, but I haven’t used it long enough to see results yet. Have any of you dealt with this? What do/did you do to help? (It’s not from an infection or STD, I was tested last month)
