Actions that make the skin sensitive

In reality, people with naturally sensitive skin are rare. Unfortunately, in most cases where people perceive their skin as sensitive, they have actually made it sensitive themselves. Major causes include excessive chemical peeling and scrubbing, the use of irritating ingredients like high-concentration retinol and pure vitamin C without an adaptation period, and vigorously rubbing the skin with rough cotton pads or brushes. In such cases, countless microscopic abrasions are created on the skin, allowing external bacteria and pollutants to penetrate and leading to the destruction of the skin barrier.
