This is a great multitasking serum which visibly nourishes and restores my skin. It contains 2.5% Ceramide Boosters, which are powerful moisturisers that penetrate the deeper layers of skin to support ceramide production from within and help improve the skin’s barrier function. The serum seals in moisture to soothe and strengthen the skin barrier, and it also contains 1% Niacinamide (Vitamin B3) which gives soft and youthful-looking skin. I’ve always loved Simple products as they are effective skin care products that are free from harsh chemicals.
