The answer to whether you should apply sunscreen before or after moisturizer depends on the type of sunscreen you are using. If you are using a non-mineral sunscreen, it is recommended to apply it before your moisturizer, as it needs to be absorbed into the skin to provide sun protection. On the other hand, if you are using a physical sunscreen (also known as mineral sunscreen), it should be applied after your moisturizer, as it sits on top of the skin and creates a barrier between the skin and the sun.
It is important to note that some dermatologists disagree on this matter, as moisturizer can interfere with the effectiveness of sunscreen, and vice versa. However, a general rule of thumb is to apply sunscreen as the final step in your skincare routine, after cleansing, toning, and moisturizing. If you are using a moisturizer with SPF, make sure it has an SPF of at least 30 and apply it as the last step in your skincare routine.
In summary, the answer to whether you should apply sunscreen before or after moisturizer depends on the type of sunscreen you are using. If you are using a non-mineral sunscreen, apply it before your moisturizer, and if you are using a physical sunscreen, apply it after your moisturizer. Regardless, always make sure to apply sunscreen as the final step in your skincare routine.
