Detailed answer

Spider veins, also known as telangiectasias, are caused by the enlargement of small blood vessels near the skin's surface. Dry skin alone does not cause spider veins, but it can exacerbate their appearance. The actual cause of spider veins includes genetics, age, hormonal changes, obesity, prolonged sitting or standing, and sun exposure. Dry skin can make spider veins more noticeable since it lacks moisture and may accentuate fine lines and redness, making the veins more apparent. Maintaining proper skincare, using moisturizers, protecting the skin from excessive sun exposure, and managing other underlying factors can help reduce the visibility of spider veins.
