People tend to believe that they have sensitive skin when they use certain products that don't suit them and causes some redness, itching, blotches, rashes, etc. However, this is not true. Sensitive skin is actually used to describe a condition when skin develops rashes, skin bumps, erosions, pustules, blotches, redness and so on when exposed to harsh weather conditions such as extreme heat, wind or cold.
There are some common skin ailments for that may harm a sensitive skin; i.e. Acne, rosacea, burning and stinging as well as contact dermatitis or irritants and allergies. Skin can be sensitive on any part of the body, including legs, arms, hands, etc. but it is most noticeable on the face though. The degree of sensitivity varies from person to person. Sensitive skin easily reacts when exposed to sunlight or wind. Also, such a skin is more prone to dryness, itchiness and redness. So, in case you have a sensitive skin you need to be extra cautious with the foods you eat and the products you use.
Precautions to be taken in case of a sensitive skin:
However, if you do have any prolonged, unexplained skin reaction then you should visit your dermatologist who might conduct a skin allergy test to identify the root cause of the problem. Finally, limit your alcohol intake. In case you have a concern or query you can always consult an expert & get answers to your questions!
