Q How can I avoid scratching when it's unbearably itchy? Why does scratching make it worse?
A Scratching damages the skin barrier, and the scratched area releases even more itch-inducing substances, creating a vicious cycle. Cold compresses, pressing with a fingernail, and cooling moisturizers are immediate alternatives.
Detailed Answer
Scratching destroys the skin barrier and triggers additional release of cytokines from keratinocytes, creating a vicious cycle in which the itch becomes stronger. Repeated scratching causes lichenification, in which the skin becomes thick and rough, lengthening the treatment period. When the urge to scratch arises, lightly pressing with a fingertip or placing a cold wet towel or cold pack can block the immediate itch signal.
Korean Medicine Clinic Perspective
During skin treatment at Dongjedang, we recommend using a cooling moisturizing spray and wearing thin cotton gloves before bed. Reducing unconscious nighttime scratching noticeably speeds up treatment. For those with severe itching during sleep, the prescription taken before bed can also be adjusted.
