Getting older Too little sebum is produced, and the skin’s ability to retain moisture is reduced, which makes it drier and drier.
Exfoliate excessively Excessive exfoliation can damage the skin barrier, and once that barrier is damaged, the skin’s ability to hold water is reduced.
Climate change Climate change can cause abnormal secretion of sebaceous and sweat glands, which may become habitual dryness over time.
Bad habits Lack of sleep/excessive weight loss and diet/poor blood circulation, skin cells lose their vitality.
