Introduction
Skin is the largest organ of the human body, and it plays an essential role in protection, temperature control, and sensory function. Because the skin is exposed to the environment every day, it is sensitive to many factors such as weather, allergens, friction, stress, diet, chemicals, and hygiene products. As a result, many people experience periods where the skin becomes irritated, bumpy, discolored, or inflamed.

Understanding Skin Reactions: Why They Happen

Some common categories of causes include:

Allergic Reactions

Irritation or Mechanical Friction

Lifestyle and Hygiene Factors

Underlying Sensitivity or Skin Type
Each of these can influence how the skin behaves.
