Dull, dehydrated skin can stem from a variety of factors, ranging from lifestyle habits to environmental influences.

One primary cause of dull, dehydrated skin is a lack of proper hydration. When the skin lacks sufficient moisture, it can appear dry, flaky, and rough, leading to a lacklustre complexion. Dehydration can result from inadequate water intake, harsh weather conditions, excessive sun exposure, or the use of harsh skincare products that strip the skin of its natural oils.

Another common culprit is a compromised skin barrier function. When the skin's protective barrier is weakened, it is less able to retain moisture effectively, leading to dehydration. This can be caused by factors such as over-exfoliation, using harsh chemicals, or exposure to environmental stressors like pollution and UV rays.

Nutritional deficiencies, particularly in essential vitamins and antioxidants, can also contribute to dull, dehydrated skin. A lack of nutrients necessary for skin health can result in a loss of radiance and vitality.
