Symptoms of sensitive skin mainly include redness, flaking, itching, and a sense of burning or tightness. Likewise, sensitive skin can quickly develop rashes with pustules, papules or swelling. Sensitive skin tends to react to external stimuli and environmental influences very rapidly and often rather strongly. These include, for example, cold, heat, irritating ingredients in cosmetics, sunlight or environmental pollution. Redness and a burning sensation occur after a hot bath, for example, or after using facial cleansers that are too aggressive. People with sensitive skin tend to have a fair complexion that is prone to sunburn.
