6.2 Skin Analysis & Contraindications

Skin Analysis & Contraindications

After cleansing, skin analysis is the diagnostic heart of every facial. Virginia estheticians use the naked eye, a magnifying lamp (loupe), and sometimes a Wood's lamp or imaging device to evaluate skin before selecting products and procedures. Equally important is recognizing contraindications—conditions that prohibit or limit treatment. NIC exams heavily weight this material because misjudgment causes injury, infection spread, and Board complaints.

Conducting Skin Analysis

Perform analysis on cleansed, makeup-free skin under adequate lighting. A magnifying lamp with 5× diopter magnification reveals texture, comedones, capillaries, and dehydration lines invisible to the naked eye.

The Analysis Sequence

1. Visual inspection: Overall color, symmetry, lesions, edema.
2. Magnified examination: Pore size, comedones, milia, telangiectasia, scarring.
3. Touch (palpation): Texture, temperature, elasticity, oiliness.
4. Client interview: Confirm sensations (tightness, burning, itching) and home care.

Document Findings

Record skin type (normal, dry, oily, combination), conditions (dehydration vs. alipidic, acne grade, rosacea, hyperpigmentation), and Fitzpatrick type (I–VI) based on burn/tan response. These findings drive product selection and modality intensity.

Fitzpatrick Skin Typing

The Fitzpatrick scale classifies skin's response to UV exposure:

• Type I: Very fair, always burns, never tans.
• Type II: Fair, usually burns, tans minimally.
• Type III: Medium, sometimes burns, gradually tans.
• Type IV: Olive or light brown, rarely burns, tans easily.
• Type V: Brown, very rarely burns, tans darkly.
• Type VI: Deeply pigmented brown to black, never burns.

Fitzpatrick typing informs chemical exfoliant selection, IPL/LED settings (when within scope), and post-inflammatory hyperpigmentation (PIH) risk. Types IV–VI are more prone to PIH after aggressive extractions, waxing, or peels; use gentler modalities and emphasize sun protection.

Wood's Lamp (When Available)

A Wood's lamp uses UV-A light to highlight certain conditions:

• Pale blue: Normal healthy stratum corneum.
• White fluorescence: Hypopigmentation or dehydration.
• Purple fluorescence: Thick corneum or product residue.
• Coral pink: Porphyrins from Cutibacterium acnes in follicles.
• Golden yellow: Oily skin with sebum fluorescence.

Not all conditions appear under Wood's light; use it as a supplement, not a sole diagnostic tool.

Dehydration vs. Alipidic Skin

Students frequently confuse dehydration (lack of water) with alipidic skin (lack of oil). A client can have oily skin that is dehydrated—shine on the T-zone with tight, flaky patches indicates insufficient water, not insufficient cleanser strength. Treatment differs: dehydrated skin needs humectants and hydrating toners; alipidic skin needs lipid-rich creams. Document which condition you observe because product selection depends on accurate differentiation.

Skin Typing: Oily, Dry, Combination, Normal

Oily skin produces visible sebum within hours of cleansing, enlarged pores on the T-zone, and may show comedones. Dry (alipidic) skin lacks sebum, appears dull, and may feel rough. Combination skin shows oiliness centrally with normal or dry periphery. Normal skin has balanced sebum, small pores, and even texture—rare in adult clients without maintenance. Most clients require zone-specific protocols rather than a single product line for the entire face.

Contraindications: Absolute vs. Relative

Absolute Contraindications (Do Not Treat)

Refuse service and reschedule or refer when the client has:

• Contagious skin diseases: Impetigo, active herpes simplex, fungal infections (tinea), scabies, conjunctivitis.
• Open wounds, ulcers, or weeping lesions in the treatment area.
• Severe sunburn or radiation burn on the face.
• Known allergic reaction to planned products without alternative plan.
• Intoxication or inability to consent.

Relative Contraindications (Modify or Obtain Clearance)

Service may proceed with adjustments or physician approval:

• Pregnancy: Avoid strong retinoids, high-salicylate peels, and some essential oils; shorten steam; gentle protocols only.
• Rosacea (active flare): No steam, friction, or aggressive extraction; cool soothing products.
• Diabetes: Higher infection risk; gentle techniques; physician note for compromised skin.
• Hypertension (uncontrolled): Avoid prolonged massage and excessive heat.
• Recent cosmetic surgery or injectables: Wait until physician releases for facial massage and pressure.
• Topical retinoids / isotretinoin: No waxing on treated areas; reduce exfoliation intensity.
• Eczema or psoriasis (acute flare): Soothe only; no exfoliation or extraction on inflamed plaques.

Scope Boundary: Analysis vs. Diagnosis

Estheticians analyze skin to customize beautification treatments. They do not diagnose diseases. Phrases like "You have eczema" cross into medical practice. Instead: "I observe redness and scaling consistent with irritation; I recommend you see a dermatologist for diagnosis before we exfoliate."

When analysis reveals a suspicious lesion (asymmetry, irregular border, multiple colors, diameter >6 mm, evolving), halt treatment on that area and urge dermatologic evaluation using the ABCDE melanoma framework learned in skin disorders training.

Building the Treatment Plan

Synthesize analysis and contraindication screening into a written plan:

• Cleanser type
• Steam duration (or omission)
• Exfoliation method and strength
• Extraction yes/no
• Mask type
• Finishing products and SPF

Review the plan with the client before proceeding. This communication prevents complaints and demonstrates professional judgment expected of Virginia licensees.
