What is a consequence of using a superficial steam treatment for too long?

Using a superficial steam treatment for too long can lead to broken capillaries. Prolonged exposure to heat causes the blood vessels near the skin's surface to expand. This expansion can weaken the walls of the capillaries, making them prone to rupture. When they break, this can result in visible redness or spider veins on the skin, which can be a cosmetic concern for many clients. Understanding this consequence is essential for providing safe and effective treatments, ensuring that the steaming duration is appropriate to avoid skin damage while still attaining the desired results.
