### Understanding the Skin Your skin is the body's largest organ and serves as a protective barrier against environmental hazards like bacteria, chemicals, and temperature changes. It also helps regulate body temperature and enables the sensation of touch, heat, and cold. #### Layers of the Skin 1. **Epidermis**: The outermost layer that provides a waterproof barrier and creates our skin tone. 2. **Dermis**: Beneath the epidermis, it contains tough connective tissue, hair follicles, and sweat glands. 3. **Hypodermis**: The deeper subcutaneous tissue made of fat and connective tissue. #### Common Skin Ailments 1. **Eczema**: A condition that makes your skin red and itchy. It's common in children but can occur at any age. Treatment includes moisturizing creams and corticosteroids. 2. **Psoriasis**: A skin disease that causes red, itchy scaly patches, most commonly on the knees, elbows, trunk, and scalp. Treatments include topical ointments, light therapy, and medications. 3. **Acne**: A skin condition that occurs when hair follicles are clogged with oil and dead skin cells. Treatments range from over-the-counter remedies to prescription medications. 4. **Rosacea**: A chronic skin condition that causes redness and visible blood vessels in your face.
