Keeping track of all the products that work for you—what causes an allergic reaction or triggers related to an acne flareup—can be challenging. That’s why beauty experts recommend keeping a skincare journal. Daily journaling can help you keep track of flares and triggers if you suffer from inflammatory skin conditions. Or if you’ve introduced a new product to your routine, it can help you determine whether or not it’s working. It doesn’t need to be grueling or tedious, even a few quick bullet points or daily observations jotted into your daily journal will do the trick.
