Available exclusively at Sephora, the dermatologist-tested range is designed for [sensitive and rosacea-prone skin](https://www.trendhunter.com/trends/rosacea-awareness-month) and has been accepted by the National Rosacea Society. Central to the collection is the A-CICA365 Soothing Redness Relief Face Serum, featuring pH4.5CICA™, a proprietary complex combining Centella Asiatica with zinc, PHA and niacinamide. The products use a cross-linked hyaluronic acid network to progressively deliver the complex while helping maintain a mildly acidic pH of 4.5 for up to 12 hours, supporting the skin's protective acid mantle and moisture barrier. The A-CICA365 Soothing Relief Serum pH4.5 anchors the routine, with testing showing visible redness reduced by 15% immediately and 63% after one week. It also targets skin temperature, sensitivity and barrier discomfort. As sensitive-skin consumers become more informed about the mechanisms behind irritation, products are moving beyond generalized calming claims toward more targeted solutions. For skincare brands, AESTURA's pH-focused approach shows an opportunity to pair familiar [soothing ingredients](https://www.trendhunter.com/trends/calming-serum) with differentiated technologies that explain not only what a product addresses, but how it supports healthier-looking skin over time.
