A facial "glow" is a term often used in the beauty and skincare industry to describe a treatment or series of treatments designed to instantly revitalize the skin, leaving it looking brighter, fresher and more radiant. This type of treatment aims to revive the skin's natural radiance and reduce signs of fatigue, dullness and skin aging.

A dull complexion on the face can be caused by several factors, which can act alone or in combination to give the skin a tired, lifeless and lacklustre appearance. Here are some of the main causes of a dull complexion:

• Lack of hydration: Insufficient hydration of the skin can lead to a lack of radiance and suppleness. Dehydrated skin can look dull and have a rough texture.
• Lack of sleep: Lack of sleep can lead to tired, dull skin. During sleep, the skin regenerates and repairs itself, so insufficient sleep can negatively affect skin appearance.
• Poor diet: An unbalanced diet rich in processed foods, refined sugars and saturated fats can have an impact on skin health. Deficiencies in essential nutrients such as vitamins and minerals can also contribute to a dull complexion.
• Sun exposure: Excessive exposure to the sun and UV rays can damage the skin, leading to discoloration, pigmentation spots and a dull complexion.
• Stress: Chronic stress can have a detrimental effect on skin health by upsetting hormonal balance and increasing cortisol production, which can lead to dull, blemish-prone skin.
• Smoking: Smoking is associated with reduced blood circulation and a reduced supply of oxygen and nutrients to the skin, which can lead to a dull, prematurely aged complexion.
• Dehydration: Skin dehydration can be caused by external factors such as exposure to wind, cold and dry air, as well as internal factors such as excessive perspiration or poor hydration.
• Skin aging: With age, skin loses its elasticity and ability to renew itself, which can lead to a dull complexion and lack of firmness.
