Sensitive skin doesn’t only react to ingredients—it can react to mechanical stress, too much friction, roughness, and repeated rubbing.
Researchers often discuss barrier health using TEWL (transepidermal water loss). When the barrier is disrupted, TEWL tends to increase—one reason aggressive tools can feel like “too much,” fast.
That’s why the same shower routine can feel totally different depending on the tool—and why “more aggressive” isn’t the answer.
