Spotted a constellation of small bumps on your skin? Don't panic! These tiny terrors are usually harmless, but understanding their cause can bring peace of mind. Several culprits could be behind them.
**Common Causes:**
* **Keratosis Pilaris:** These are those rough, tiny bumps often found on the upper arms and thighs, resembling goosebumps. They're caused by a buildup of keratin, blocking hair follicles.
* **Acne:** Not just for teenagers! Tiny bumps can be the early stages of acne, either whiteheads (closed comedones) or blackheads (open comedones).
* **Milia:** These are small, white, cyst-like bumps that commonly appear around the eyes and nose. They're caused by trapped keratin under the skin's surface.
* **Allergic Reactions:** Contact dermatitis from irritants like soaps, lotions, or certain fabrics can manifest as tiny, itchy bumps.
* **Heat Rash:** In hot and humid conditions, sweat can get trapped under the skin, leading to small, red bumps.
If the bumps are itchy, painful, or spreading rapidly, consult a dermatologist for a proper diagnosis and treatment plan. While most small bumps are benign, it's always best to err on the side of caution!
