Our Kalme Day Defence SPF25 is designed for sensitive skin and is particularly low reactivity. Our Day Defence SPF30 is not as calming as it uses a chemical sun filter. Whereas the SPF25 is 100% mineral and in our experience is fantastically low reactivity and works well even on very sensitive skin.
But always patch test any new cream. Everybody's skin is different and what might be great on me may react badly with you. So always patch test and make sure you leave on your skin for 24 hours before you cover your face with anything new.
