Key Takeaways
- The five primary skin types are normal, dry, oily, combination, and sensitive
- Fitzpatrick scale (I-VI) classifies skin by UV response and guides treatment settings
- Total contraindications (infections, fever) prevent all treatment; local contraindications require avoiding affected areas
- Client intake forms must include medical history, allergies, medications, and consent
- Magnifying lamp analysis helps identify pore size, texture, hydration, and skin conditions
Skin Analysis & Consultation
Proper skin analysis and consultation form the foundation of all esthetic services. This section covers 10% of the NIC Cosmetology exam and focuses on identifying skin types, conditions, and contraindications.
The Five Primary Skin Types
The American Academy of Dermatology recognizes five primary skin types based on sebum production and skin characteristics:
| Skin Type | Characteristics | Common Concerns |
|---|---|---|
| Normal (Eudermic) | Balanced moisture and sebum, small pores, smooth texture, even tone | Rarely experiences blemishes or sensitivity |
| Dry | Lacks sebum production, feels tight, may appear dull or flaky | Fine lines, rough texture, sensitivity |
| Oily | Overproduction of sebum, enlarged pores, shiny appearance | Acne, blackheads, makeup breakdown |
| Combination | Oily T-zone (forehead, nose, chin) with dry cheeks | Requires different care for different areas |
| Sensitive | Reactive to products/environment, redness, itching, tightness | Inflammation, allergic reactions |
Fitzpatrick Skin Typing Scale
The Fitzpatrick scale classifies skin by its response to UV exposure. This is essential for determining treatment settings, especially for laser and light therapies.
| Type | Skin Color | Sun Reaction | Characteristics |
|---|---|---|---|
| Type I | Pale white, ivory | Always burns, never tans | Often has freckles, red or blonde hair, blue eyes |
| Type II | White, fair | Usually burns, tans minimally | Light hair, light eyes |
| Type III | Medium white to olive | Sometimes burns, tans uniformly | Brown hair, hazel or brown eyes |
| Type IV | Olive, moderate brown | Rarely burns, tans easily | Dark brown hair and eyes |
| Type V | Brown, dark brown | Very rarely burns, tans very easily | Dark hair and eyes |
| Type VI | Very dark brown to black | Never burns | Deeply pigmented skin |
Clinical Significance:
- Types I-II: Higher skin cancer risk, need stronger sun protection
- Types V-VI: Higher risk of hyperpigmentation from treatments
- Laser settings must be adjusted based on Fitzpatrick type to prevent burns or hypopigmentation
Skin Conditions vs. Skin Disorders
Understanding the difference between conditions and disorders is crucial for proper treatment:
Skin Conditions (Can be treated by estheticians):
- Dehydration
- Sensitivity
- Aging/fine lines
- Hyperpigmentation

- Milia
Skin Disorders (Require medical referral):
- Acne vulgaris (severe)
- Rosacea
- Eczema
- Psoriasis
- Skin cancer
- Herpes simplex (cold sores)
- Dermatitis

Total Contraindications (No treatment allowed):
- Contagious diseases (flu, COVID, chickenpox)
- Bacterial infections (impetigo, conjunctivitis, boils)

- Recent head/neck injury
- Fever
Local Contraindications (Avoid affected area):
- Open wounds, cuts, abrasions

Magnifying Lamp Analysis
The magnifying lamp (loupe) is an essential tool for thorough skin analysis:
Proper Technique:
- Position client comfortably with eyes closed
- Adjust lamp to 3-5 inches from the face
- Examine skin systematically: forehead, nose, cheeks, chin
- Look for pore size, texture, hydration, pigmentation
- Document findings on analysis card
What to Look For:
- Comedones and milia
- Dehydration lines vs. wrinkles
- Broken capillaries
- Hyperpigmentation
- Skin texture and elasticity
- Pustules or papules
