Skin Anatomy

Epidermis

• Outermost layer of the skin
• Composed of stratified squamous epithelium
• Functions:
  • Barrier against external factors (water loss, temperature regulation)
  • UV protection
  • Immune response

Dermis

• Middle layer of the skin
• Composed of connective tissue
• Functions:
  • Provides strength and elasticity
  • Regulates body temperature
  • Houses hair follicles, sebaceous glands, and sweat glands

Hypodermis

• Innermost layer of the skin
• Composed of loose connective tissue
• Functions:
  • Attaches skin to underlying tissues
  • Stores energy in the form of fat

Skin Conditions

Acne

• Inflammatory skin condition
• Caused by:
  • Clogged pores
  • Bacterial overgrowth
  • Hormonal fluctuations
• Symptoms:
  • Pimples
  • Blackheads
  • Whiteheads
  • Inflammation

Psoriasis

• Chronic autoimmune condition
• Caused by:
  • Overactive immune response
  • Genetic predisposition
• Symptoms:
  • Red, scaly patches
  • Itching
  • Dry skin

Melanoma

• Type of skin cancer
• Caused by:
  • UV radiation
  • Genetic mutations
• Symptoms:
  • Asymmetrical moles
  • Irregular borders
  • Multicolored moles
  • Diameter >6mm

Skin Anatomy

Epidermis

• Outermost layer of the skin, composed of stratified squamous epithelium
• Barrier against external factors, including water loss and temperature regulation
• Provides UV protection and initiates immune response

Dermis

• Middle layer of the skin, composed of connective tissue
• Provides strength and elasticity to the skin
• Regulates body temperature and houses hair follicles, sebaceous glands, and sweat glands

Hypodermis

• Innermost layer of the skin, composed of loose connective tissue
• Attaches skin to underlying tissues and stores energy in the form of fat

Skin Conditions

Acne

• Inflammatory skin condition caused by clogged pores, bacterial overgrowth, and hormonal fluctuations
• Characterized by symptoms such as pimples, blackheads, whiteheads, and inflammation

Psoriasis

• Chronic autoimmune condition caused by overactive immune response and genetic predisposition
• Symptoms include red, scaly patches, itching, and dry skin

Melanoma

• Type of skin cancer caused by UV radiation and genetic mutations
• Characterized by symptoms such as asymmetrical moles, irregular borders, multicolored moles, and diameter >6mm
