Compromised Skin Barrier:
• When the physical and lipid components of the skin barrier are compromised, irritants can easily penetrate the skin, leading to inflammation. External factors such as harsh weather conditions, excessive cleansing, or the use of certain skincare products/ingredients can all contribute.

Allergies:
• Both internal and external allergens can trigger inflammatory tendencies or cause direct inflammation of the skin.

Medication:
• Certain medications can contribute to skin sensitivity. It is important to be aware of any potential skin reactions associated with medications and consult your GP if necessary.

Neurobiological Factors:
• In some cases, individuals may have a higher density of nerve endings in their skin or experience abnormal nerve behaviour, which can contribute to heightened sensitivity and discomfort.

Topical Ingredients and Abrasion:
• Certain topical ingredients, such as retinols or strong concentrations of actives, can cause skin reactions in sensitive individuals. Similarly, physical abrasion from rough exfoliants or harsh scrubbing can aggravate sensitive skin.

External Aggressors:
• External factors like ultraviolet (UV) radiation from the sun can trigger inflammation and worsen skin sensitivity. Always wear an SPF and look for products with antioxidant protection.
