Skin Care 3 Quiz Review: Weeks 1-3

• Overview of the Skin:

  • The skin is the largest and most complex organ in the body, part of the integumentary system.
  • Healthy skin is elastic, soft, and pliable.
  • Skin composition includes 70% water, 27% proteins, 2% lipids, and 1% carbohydrates.
  • Thickest on palms and soles, thinnest on eyelids.
  • Contains millions of sweat glands, blood vessels, and nerves.

• Functions of the Skin:

  • Protection against bacteria, irritants, and UV radiation.
  • Regulation of body temperature.
  • Removal of toxins (through sweat).
  • Production of Vitamin D.

• Layers of the Skin:

  • Epidermis: Outer waterproof layer, protects from infection.
  • Dermis: Contains hair follicles, glands, and nerves.
  • Hypodermis (Subcutaneous Layer): Provides insulation and cushioning.

• Epidermis and Its Layers:

  • Stratum Corneum: Outermost layer, dead cells.
  • Stratum Lucidum: Found in thick skin (palms and soles).
  • Stratum Granulosum: Keratinization begins here, reducing water loss.
  • Stratum Spinosum: Thickest layer, strengthens skin.
  • Stratum Germinativum (Basal Layer): New skin cells (keratinocytes) are created.

• Key Cells in the Epidermis:

  • Keratinocytes: 90-95% of epidermal cells, responsible for skin strength.
  • Melanocytes: Produce melanin, protects skin from UV damage.
  • Langerhans Cells: Part of the immune system, fights infections.
  • Merkel Cells: Help with touch sensation.

• Keratinocyte Life Cycle:

  • Born in the Stratum Germinativum.
  • Move up through the epidermis.
  • Eventually die and become part of the Stratum Corneum (desquamation).
  • Life cycle is about 10-15 days (slows with age).

• Important Terms:

  • Desmosomes: Proteins holding skin cells together.
  • Odland Bodies: Contain ceramides and fatty acids, help form skin barrier.
  • TEWL (Transepidermal Water Loss): Water lost from the skin; Stratum Granulosum helps reduce it.

Indirect High Frequency

• Overview of Electrical Treatments:

  • Electrical treatments are faster and more intense than manual treatments.
  • Used for treating facial and body skin.
  • Improve skin condition, texture, muscle tone, and overall body condition.

• Choosing Equipment:

  • Equipment is expensive, so careful consideration is needed.
  • Check equipment's reputation, safety certification (CE mark), and warranty.

• Indirect High Frequency:

  • Uses alternating (oscillating) electrical current.
  • Creates vibrations and heat, stimulating the skin.
  • Effects include increased activity of sebaceous and sudoriferous glands, increased blood circulation, enhanced lymphatic circulation.

• Contraindications to Indirect High-Frequency:

  • Skin issues like inflammation and acne rosacea.
  • Medical conditions like migraines and heart conditions.
  • Recent treatments such as Botox, fillers, excessive dental metalwork, and recent cosmetic treatments.

• High Frequency Electrodes:

  • Different electrode types used depending on the treatment (mushroom, horseshoe, saturator, spiral intensifier, roller).

SRS Treatment (Structural Remodeling System)

• Understanding Skin Aging:
  • Aging affects the integument, sub-integumentary adipose tissue, muscles, and bone tissue.
  • Effects include thinning epidermis, reduced cell turnover, collagen and elastin loss, fragile skin, and dehydration.
  • Muscle aging leads to sarcopenia and sagging.
  • Bone aging causes demineralization, osteoporosis, and joint pain.
• Role of SRS Machine in Anti-Aging:
  • Firms sagging muscles, increases local blood/lymph circulation, stimulates fibroblast activity, promotes collagen synthesis, restores cellular homeostasis.
• Technologies Used in SRS Machine:
  • Ultrasound, high voltage pulsed current (HVPC), high voltage short pulsed current (HVSPC)/electroporation, galvanic current (iontophoresis), pulsed micro-currents.
• Treatment Procedures:
  • Treatment schedule depends on initial skin evaluation (6, 8, or 10 sessions).
  • Best Candidates = facial skin age under 50, early signs of aging, Glogau classification I, II, or III.
  • Standardized treatment zones (forehead/T-zone, cheeks/jaw, face oval/neck) and Important: Avoid thyroid gland and carotid arteries during neck treatment.
  • Visible results usually by 2nd or 3rd session. Results can improve by up to 5-10 years. Best results using personalized treatment plans.
