This is because sensitive skin includes several skin conditions, not just a health condition. You may have the impression that you have sensitive skin, struggling with problems due to the self-diagnosis of sensitive skin, but sometimes it is difficult for dermatologists to treat and diagnose sensitive skin that has no apparent problems such as irritation, redness, itching or nausea. Both groups of people, who have a clear skin problem but also no skin condition, have sensitive skin and the problem is incomplete understanding of the skin reaction in a certain way.
 
People with sensitive skin often have contact dermatitis. Your skin can respond to products, ingredients, own sweat, too much sun or narrow clothing. You may think you are allergic to these things, but dermatitis is not the same as allergies. Sensitive skin is easily inflated skin that is more reactive to certain ingredients or products. Allergic skin reactions can occur to anyone, not just the sensitive person. The appearance of sensitive skin is more common in women and the largest increase in people with sensitive skin is observed in Asian countries.

Your skin barrier is designed to protect you. Its outer layer helps keep moisture away so that the body does not dry out. Sensitive skin may be more pervasive than normal skin. That means it does not work well as an obstacle. It may be that your skin does not have enough ceramides. These fatty acids help your skin to act as a protective layer. People with low levels of ceramide often have sensitive skin reactions. Skin sensitivity can be caused by hot or cold temperatures or low humidity. If you use a lot of dry skin care products, you can react to one of the products.

Your skin also responds to what's going on in your life. People with sensitive skin often experience more stress, anxiety, or tension. Your skin feels extra stress and responds to it.

One way to avoid or to some extent reduce sensitive skin problems is to thoroughly check your face care routine, read the ingredients of the product you are using and compare with products that do not irritate your skin. The most common problematic substances are alcohol, sulphates, benzene peroxides and caution is advised with retinoids. Sensitive skin can still use retinoids but with lower concentrations or after moisturizing creams and oils that will reduce the absorption of retinoids into the skin.
