What causes dull skin?
Going from a luminous, radiant skin to a tired-looking, dull complexion can be a frustrating process, and there are several possible reasons behind it. The first and most prominent reason for a skin that looks dull is an excess of dead skin cells; if your natural shedding process isn't working efficiently, these cells will accumulate overtime on the epidermis (the skin's surface). This creates a barrier of clogged pores, resulting in the undesired appearance of dull skin with gray undertones.

Other factors that can cause dull skin include:
1. Poor circulation, which prevents the skin brightening effects of blood vessels;
2. Skin aging, which slows down the cell renewal process;
3. Poor skin hydration, given the lack of moisture in dry, dehydrated skin can result in a lackluster skin tone;
4. Stress and fatigue, which can translate into a dull face and a skin that looks tired;
5. Smoking, which decreases the amount of oxygen and nutrients that reach your skin;
6. An unhealthy diet including highly processed foods, excessive caffeine and alcohol, and a high fat and sugar intake, which can lead to skin inflammation and the breakdown of collagen, resulting in face dullness;
7. Environmental factors such as air pollution, low humidity and UV exposure, which can create free radicals on the skin and stimulate skin hyperpigmentation.
