Capillaries are tiny blood vessels under the skin’s surface. They are quite fragile and can break easily from pressure, from vigorous scrubbing, or even from excessive sun exposure. When capillaries break, they form a web like pattern, which is why they are also known as spider veins. The body areas most susceptible to broken capillaries are the face and legs when the skin is thin. An ingredient with clinical evidence of efficacy in reducing the appearance of spider veins is natural horse chestnut, formulated into the derma e® Clear Vein Crème.
