Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Low estrogen can cause irregular periods,moods swings essues,fatigue,depression,low libido,dry skin and dry eyes,hot flashes etc Rosacea is a common skin disease. It often begins with a tendency to blush or flush more easily than other people. Abnormalities in the blood vessels of the face cause the flushing, persistent redness, and visible blood vessels. Rosacea is often aggravated at menopause and in other circumstances with low estrogen. So,Yes,your symptoms can be atributted to your low estrogen level. Estrogen therapy or hormone replacement therapy(progesterone is often used in conjunction with estrogen) can be helpful to ease your symptoms.At the other side there are even serious side effects or rscs that should be taken in consideration. Hormone Replacement Therapy may have an increased risk of cardiovascular disease, blood clotting, stroke, and breast cancer. My advice is to consult your treating doctor and discuss with him the benefits and the riscs of estrogen therapy or hormone replacement therapy so you can decide what is the best solution for your condition. Hope I have answered your query. Let me know if I can assist you further
