Sensitive Skin is usually a genetic condition where sensitized skin is usually a result of external factors. The protective lipid barrier in sensitive or sensitized skin is usually thinner than other skin types. This condition allows irritants, microbes and allergies penetrate the skin and cause adverse reactions such as skin redness and rosacea. People with sensitive skin, redness or rosacea are usually more prone to asma, allergies and blushing.
