Skin different kinds of rash is one of the most common skin problems worldwide. They can appear suddenly or develop slowly over time, and may show up as redness, bumps, blisters, or scaly patches.

- Environmental factors: Heat, sweat, humidity, chemicals in soaps, perfumes, or detergents.
- Chronic skin conditions: Eczema, psoriasis, rosacea.
- Stress: Emotional stress often triggers flare-ups of eczema, hives, or psoriasis.
