Feelings of anxiety and depression are one of the biggest drivers of bad mood. Depression produces higher levels of cortisol in the blood stream. This leads to premature hair loss, skin pigmentation, increased fat content in the hip areas, and foul mood. Depression also causes skin rupture. Sadness is another by-product of depression. Repeated frowning and furrowing of eyebrows, due to depression, can deepen the wrinkle lines on your face. Prolonged depression is disastrous for skin. It triggers hormones that can affect sleep-patterns, thus leading to puffy eyes and dull complexion.
