Skin Health

Body Parts and Structures Involved

Skin Layers

• Epidermis – Protective outer barrier with keratinocytes and melanocytes.

• Dermis – Contains collagen, elastin, blood vessels, and nerve endings.

• Hypodermis – Subcutaneous fat layer for insulation and protection.

Associated Structures

• Hair follicles – Growth and sebum production.

• Sebaceous glands – Oil production for skin protection.

• Sweat glands – Temperature regulation and toxin elimination.

• Blood vessels – Nutrient delivery and waste removal.

• Lymphatic vessels – Immune cell transport and fluid balance.

Key Functions

Protective Barrier

• Physical protection from environmental damage.

• UV radiation defense through melanin production.

• Antimicrobial barrier preventing pathogen entry.

• Acid mantle maintenance (optimal pH 4.5–6.5).

Regulatory Functions

• Temperature control via vasodilation/constriction.

• Vitamin D synthesis from sunlight.

• Toxin elimination through sweat.

• Fluid and electrolyte balance.

Sensory Functions

• Detection of touch, pressure, temperature, and pain.

• Environmental awareness and protection.

Interconnections with Other Systems

• Digestive System – Gut health directly affects skin appearance and inflammation.

• Endocrine System – Hormones influence oil production, acne, and skin texture.

• Immune System – Skin provides first line of defense and reflects internal inflammation.

• Detoxification – Liver function impacts skin clarity and toxin elimination.

• Circulatory System – Blood flow affects skin nourishment and healing.

Common Symptoms

• Acne and breakouts;

• Eczema and dermatitis;

• Rosacea;

• Dry, flaky, or oily skin;

• Hair and nail problems.
