FAQ

  • Q.What’s the biggest difference compared to the previous version?

    more view

    A.Before the renewal, the focus was mainly on caring for blemish marks. After the renewal, the biggest difference is that it now also helps soothe temporary redness caused by external irritation. To achieve this, the formula includes pH4.5CICA ingredients that maintain the skin’s healthy, mildly acidic pH for up to 12 hours, while niacinamide preserves its original blemish-care benefits.

  • Q.How is it different from the ATOBARRIER365 Serum?

    more view

    A.While the ATOBARRIER365 Serum focuses on strengthening the skin’s moisture barrier and providing hydration, the A-CICA365 Soothing Relief Serum pH4.5 works to maintain a healthy pH shield, helping care for blemish marks and temporary redness often caused by external irritation on sensitive skin.

  • Q.Can I use it right after dermatological treatments?

    more view

    A.The A-CICA365 Soothing Relief Serum pH4.5 has been tested and proven suitable for use after dermatological treatments. When applied consistently after such treatments, it can help calm the skin, repair the damaged barrier, and reduce skin temperature (heat sensation) within just three days.

  • Q.Is it suitable for all skin types?

    more view

    A.The A-CICA365 Soothing Relief Serum pH4.5 is formulated with 89% moisture serum content, making it ideal for delivering ample hydration.
