Study Notes
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.
