Finally, what is the most common reason for makeup to cake? It is... 'corneous' If old dead skin cells are not properly removed, it is natural for your base and color cosmetics to mix and cause your makeup to cake. However, excessive exfoliation can irritate the skin, so please exfoliate moderately, about once a week, and make sure to moisturize thoroughly afterward.
If your makeup keeps caking, please check if you have been applying it this way, and I hope you can achieve a smoother complexion :)
