Aestura A-Cica 365 Hydrating Relief Toner pH4.5 200ml

A pH 4.5 soothing toner that cares for sensitive skin environments

A mildly acidic hydrating toner designed for the first step after cleansing, when skin is at its most vulnerable. The pH 4.5 formula helps restore the skin's surface to a mildly acidic environment, and thanks to AMOREPACIFIC's proprietary technology, maintains that pH level for up to 12 hours. This derma-soothing solution quickly calms temporary redness caused by external irritants while addressing inner dryness.

Clinically proven deep hydration

The new formula delivers 186% improved deep hydration compared to the original A-Cica 365 Toner. Its efficacy has been validated through clinical testing on sensitive, redness-prone skin. It rapidly replenishes moisture in sensitive skin that loses hydration easily, and balances oil and water levels to build a healthy skin foundation.

Right after cleansing, the first step for sensitized skin

A toner is the very first skincare step you take after cleansing. It helps restore your skin's pH to a slightly acidic environment after cleansing temporarily raises it to alkaline, and preps your skin to better absorb the essence or serum that follows. This formula is specifically designed at pH 4.5 to help rebalance sensitized skin.

Use morning and night

In the morning, use it to refresh overnight sebum and create a clean base for the day ahead. In the evening, it helps calm skin that's been exposed to environmental stressors. It's especially helpful when your skin feels temporarily reactive or flushed due to seasonal changes or external irritants.

Dispense into palms and press gently

After cleansing, lightly pat your face dry. Pour about a 500-won coin's worth into your palm. Rub your hands together briefly to warm the product, then press it gently into your skin, covering your entire face. Start with larger areas like the cheeks and forehead, then work your way around the nose and along the jawline.

Recommended pairings by skin concern

• Acne-prone skin: This product has completed acne-prone skin suitability testing, so you can use it with confidence

Usage notes
