12.2 Skin Types, Fitzpatrick Typing, and Analysis

Key Takeaways

  • True skin types follow long-term oil production: dry, oily, combination, and normal. Sensitive is usually a condition overlay (reactivity) that can sit on any type.
  • The Fitzpatrick I–VI scale maps ultraviolet response — burn versus tan — not oil. Types I–II burn easily; types IV–VI carry higher post-inflammatory hyperpigmentation risk after extraction or peel.
  • Skin analysis is look, touch, and Wood’s lamp if used, after cleansing and before steam, extraction, or acid; a missing lamp does not skip look-and-touch.
  • Dehydration is lack of water and can occur on oily skin; dry is lack of oil. Aging is chronological; sun damage is UV-driven. Congestion is cosmetic; infection or eruption is a 1175.115 refuse-and-refer presentation.
  • Illinois analysis chooses a cosmetic protocol under 1175.835 and 3A-1; it does not name a disease as a diagnosis or authorize medical-treatment advice.

12.2 Skin Types, Fitzpatrick Typing, and Analysis

Quick Answer: True skin types are driven by oil: dry, oily, combination, and normal. Sensitive is usually a condition overlay (reactivity) that can sit on any type. Fitzpatrick I–VI maps UV response (burn versus tan), not oil, and sets chemical-exfoliation caution — especially PIH risk on types IV–VI. Analysis is look, touch, and Wood’s lamp if used. Dehydration is lack of water, not the same as dry (lack of oil). Illinois analysis chooses a cosmetic protocol; it does not name a disease as a diagnosis (225 ILCS 410/3A-1).

NIC II.A.2 lists skin analysis with Fitzpatrick skin types, conditions, and characteristics. Illinois 1175.835 teaches introduction to skin analysis in the 75-hour Basic Training block and skin analysis again in the 500-hour Practices and Procedures block. 1175.710 tests anatomy of the skin as it relates to applicable services under the Act. You analyze so you can choose an in-scope facial. You do not analyze so you can practice dermatology.

Makeup comes off first. A foundation-covered T-zone is not an oil reading. Good light and a magnifying lamp are the default tools. The Wood’s lamp is optional support, not a license to diagnose.

True Skin Types Versus Conditions

Skin type is the long-term sebum pattern of the sebaceous glands. It does not reset every Monday because the client used a clay mask. Skin conditions are what is happening now: dehydration, congestion, sensitivity, sun damage, aging changes, redness. Keep two columns. A person can be oily and dehydrated. A person can be dry and sun-damaged. Treating a condition as if it were a type — for example, stripping oily-dehydrated skin until it shines more — is how a “standard facial” fails.

TypeWhat you see and feelTypical protocol direction
Dry (alipidic)Fine pores, tight feel, flaking, lack of sebum, often dullCream cleanse, short steam, emollient mask, skip aggressive extraction
OilyLarger pores, shine, congestion, thicker look in the T-zone or globallyThorough cleanse, clay if intact, careful extraction only on appropriate comedones
CombinationOily T-zone (forehead, nose, chin) with drier cheeksZone the service; do not treat the face as one oil level
NormalBalanced oil, even texture, few active concernsMaintenance; do not over-treat
Sensitive (usually a condition)Stinging, redness, flushing, low product toleranceFragrance-free, short steam, no aggressive massage or peel

Some textbooks list sensitive as a fifth type. The exam-useful distinction is this: oil production sets dry, oily, combination, and normal; reactivity can overlay any of them. Do not “correct” sensitivity with a stronger acid. Do not tell an oily-sensitive client that they cannot be oily because they flush.

Normal skin in a textbook is balanced. It is not a moral grade. Most adult clients bring a type plus at least one condition. “You have combination, dehydrated, sun-damaged skin” is still not a medical diagnosis — it is a cosmetic map.

Fitzpatrick I–VI and UV Response

The Fitzpatrick scale estimates how the skin responds to ultraviolet light. It is not a race label and not an oil scale. Fair oily skin is still type I or II if it always burns. Deeply pigmented oily skin is still type V or VI. Type the UV response, then type the oil separately.

Fitzpatrick typeTypical UV responseService implication
IAlways burns, never tans; very fairHighest burn and long-term UV-damage risk; still only superficial in-scope peels
IIBurns easily, tans minimallySame burn caution; watch hairline, ears, and décolleté
IIISometimes burns, tans uniformlyDefault conservative; reassess after the first allowed service
IVBurns minimally, always tans wellPIH risk rises; lower exfoliation intensity
VRarely burns, tans easily; brownHigh post-inflammatory hyperpigmentation (PIH) risk after extraction or peel
VINever burns, deeply pigmentedHighest PIH risk from inflammation; most conservative in-scope exfoliation

Types I–II burn. They also carry higher long-term UV-damage risk, which is why you look at the face and the neck and chest while you work. That observation feeds referral when a lesion is changing; it is not a cancer diagnosis (chapter 9).

Types IV–VI tan deeply and rarely burn, but more active melanocytes produce darker skin — and they produce PIH if you over-exfoliate or over-extract. Intensity drops on IV–VI when the goal is even tone. A “medium peel for stubborn pigment” is outside Illinois esthetics on every Fitzpatrick type because medium peels affect living layers (IDFPR Statement on Prohibited Practices, 04/06/2026). Fitzpatrick typing tells you how aggressively you may use an in-scope superficial tool. It does not move a medical peel onto your menu.

Look, Touch, and Wood’s Lamp

Analysis happens after cleansing, in good light, before you commit to steam, extraction, or acid. NIC wants a method, not a vibe.

  1. Look under a magnifying lamp: pore size, color, intact versus broken skin, vessels, shine, flakes, comedones versus inflamed papules, uneven pigment. Include the hairline, sides of the nose, jaw, and neck if that skin is in the service.
  2. Touch: oil versus roughness, tautness after a blot, temperature, edema, whether a bump is a closed comedone you might extract or something you must not squeeze.
  3. Wood’s lamp (if used): a filtered ultraviolet lamp in a darkened room that highlights oil, pigmentation, and dehydration patterns. It supports look-and-touch. It does not diagnose disease. Common teaching colors: orange, yellow, or pink fluorescence with oil and comedones; brown with pigment; purple or violet with dehydration; white with a thick horny layer. If the spa has no Wood’s lamp, analysis is still complete with look and touch. Do not invent a disease name from a color.

What look-and-touch is for

  • Decide type (oil) and conditions (water, congestion, reactivity, pigment, photoaging).
  • Decide Fitzpatrick risk before any chemical or mechanical exfoliation.
  • Catch 1175.115 stop signs: inflamed, infected, or erupting skin.
  • Catch 3A-1 stop signs: an undiagnosed changing lesion is observed and referred, not “analyzed away.”

Do not skip analysis because the client “always gets the signature facial.” Do not analyze through sunscreen and makeup. Do not let a Wood’s lamp replace a conversation about medications you already collected in 12.1.

Dehydration Versus Dry, Aging Versus Sun Damage, Congestion Versus Infection

These three pairs are the exam’s favorite swaps. Mix them and you will pick the wrong mask.

Dry skin underproduces oil. Pores look finer. The face feels taut even at the end of the day. Dehydrated skin lacks water. It can look shiny and still feel tight; it can show fine dehydration lines on an oily T-zone. Harsh surfactants, over-exfoliation, dry rooms, and a stripped barrier all dehydrate oily skin. The correction is water-binding humectants and a repaired barrier, not another week of oil-stripping clay.

Intrinsic aging is chronological: slower turnover, fine lines, gradual loss of firmness that tracks years. Sun damage (photoaging) is UV-driven: mottled pigment, coarse or leathery texture, broken capillaries, and lines that may appear decades early on the face, chest, and hands. You camouflage and you talk broad-spectrum SPF as cosmetic advice. You do not “reverse photoaging” with a living-layer device, and you do not tell the client which laser a physician should order.

Congestion is cosmetic: closed comedones, milia, dull buildup without heat and pus. Infection is not a facial add-on: heat, spreading redness, pus, fever, vesicles, or a contagious eruption. 1175.115 forbids massaging skin that is inflamed or where a skin infection or eruption is present. Congestion may be extracted if the skin is intact and the lesion is a comedone you are trained to work. Infection is refuse and refer. A Wood’s lamp color does not turn an erupting pustule into “just congestion.”

Illinois: Cosmetic Protocol, Not a Diagnosis

Analysis answers four practical questions:

  1. What is the type (oil)?
  2. What conditions are present today (water, congestion, reactivity, pigment, photoaging)?
  3. What Fitzpatrick UV and PIH risk applies?
  4. Which in-scope steps are safe on this intact skin?

It does not answer “What disease is this?” Writing “client has rosacea, start medical metronidazole” is medical-treatment advice forbidden by 3A-1. Writing “visible flushing and telangiectasia on the cheeks; steam shortened; no extraction; mineral SPF assigned” is analysis. 1175.835 trained you to analyze so you can perform facial treatments. The Act did not train you to name a disease as a diagnosis.

If you see an undiagnosed changing lesion, you observe, refuse that site, and refer. You do not complete a Wood’s lamp “diagnosis.” You do not peel pigment “to confirm.” Section 12.3 then turns this map into a protocol you can actually perform.
