People with sensitive skin feel unpleasant symptoms on their face, with or without erythema (redness). These symptoms can include tingling, tightness, heating sensations or even burning and occasionally pruritus (itching). They frequently cannot tolerate many cosmetic products on their face.
What Causes Sensitive Skin?
Two main factors are responsible for this decrease in the tolerance threshold and therefore this heightened sensitivity :
First of all, the barrier function of the epidermis in sensitive and intolerant skin is impaired. This phenomenon promotes skin dehydration and the penetration of potential irritants.
It also seems that sensitive skin secretes too many pro-inflammatory cytokines (substances secreted by skin cells) and certain neuromodulators through its superficial nerve endings. These abnormal secretions then cause the unpleasant sensations felt by affected subjects. Sensitive and intolerant skin also produces too many free radicals.
TREATMENT: Wash your face with an ultra-high-tolerance soothing cleansing product, preferably one that is no-rinse, fragrance-free, preservative-free and surfactant-free. Be very careful when drying your face. Lightly pat instead of rubbinG.
COMPLETE DIAGNOSIS: Visit your dermatologist so he/she may identify factors that cause your skin to react or make it worse and give you appropriate advice. The doctor will examine you to rule out rosacea, eczema or seborrhoeic dermatitis as causes of your cutaneous hypersensitivity; these would require special treatment.
