A daily skincare product with SPF (e.g., day cream) is quite useless. It gives false expectations, because after applying it in the morning, it loses effectiveness within a few hours, which actually requires re-application. So, you’re unprotected for the larger part of the day. Also, in order to be effective, the filter should be one of the first, most important ingredients in the formula. That influences the amount of other active ingredients. Therefore, we recommend using a separate SPF.
