Unlike regular toners that only replenish skin moisture, this acid toner provides three benefits: hydration, exfoliation, and skin texture refinement. By combining water-soluble AHA with oil-soluble BHA, it effectively addresses both surface dead skin cells and impurities like excess sebum, thoroughly caring for your skin inside and out. With its mildly acidic formula and completed skin irritation tests, it's safe to use. The convenient spray type makes application easy. If using during the day, be sure to apply sunscreen.
