A healthy skin barrier acts as the first line of defense against bacteria, pollution, and irritants. When this barrier is damaged, moisture escapes and harmful elements enter, triggering inflammation and breakouts. Supporting the barrier with proper hydration helps maintain balance and reduces skin reactivity. Well-protected skin is less likely to overproduce oil or become inflamed. Over time, barrier-focused care results in calmer skin, fewer breakouts, and improved tolerance to acne treatments.
