Any cream with an SPF in it is always going to be a little greasier than a normal cream as SPF's by their very nature are a bit greasy.
However the benefits of a daily SPF to your skin if its prone to rosacea far outweigh the negative aspect of the greasiness. In addition the SPF in the Day Defence SPF25 is a pure zinc mineral block, so this not only protects the skin from UV damage (the main trigger for rosacea flare ups) but is also anti inflammatory to calm down the underlying inflammation that is the main symptom of rosacea.
So although your skin may be suffering a little more from greasiness, as you say it is much calmer so you have almost certainly been experiencing the many benefits of Day Defence SPF25.
To address the greasiness you are experiencing you may want to try one of the products from our sister skincare range Clarol. Its a range dedicated to greasy skin prone to acne. But it's still suitable for use on sensitive and rosacea prone skin types as it contains no harsh chemicals.
The product that will help you most with the greasiness is our Clarol Nordic Birch & Willow Primer. This is a bioactive mattifying primer for greasy and acne prone skin. It contains two Nordic tree bark extracts to combat oiliness, promote healthy skin microbiota and create an instantly mattified and smoother skin tone. Apply the Primer under the Kalme Day Defence and it should help control the greasiness.
The other thing you might want to consider doing is removing the Day Defence as soon as you get into the house for the evening, like when you get back from work. If you can remove it earlier it can help reduce the greasiness.
