Connecting the skin barrier to my symptoms

If the skin barrier is compromised, your skin may feel stinging and tight even if it is oily

If your skin feels severely tight after washing, hurts when applying medication, and develops dead skin cells (flaking), it is difficult to view it as skin that simply has excess sebum. It is necessary to restore the skin condition to a state where irritation is reduced and treatment can continue.

Reducing irritation does not mean giving up on acne treatment

By adjusting the amount and interval of topical medications, as well as cleansing and moisturizing, we ensure that inflammation treatment can continue. In herbal medicine treatment, we monitor not only new acne but also redness, dryness, and the speed of recovery.
