Sensitive skin: usually has genetic origins and is redness-prone with red flushes. For sensitive skin, the slightest irritation or provocation can cause a flare up at any time. A reaction may be caused by allergies, pollution, chemical irritants, illness, extreme temperatures, and other unsuitable environmental conditions. The higher histamine levels in the body can make sensitive skin more susceptible to inflammatory conditions like psoriasis, rosacea, and eczema. The visible signs of sensitive skin include chronic redness, dermatitis, chafing, broken veins and fine broken capillaries.
