Two Classifications, Two Different Questions
An esthetician answers two completely different questions about every client during skin analysis. The first question is about oil and moisture: how does this skin produce sebum and hold water? The second question is about sun reactivity: how does this skin respond to UV exposure? Each question has its own classification system, and students lose points on the state board exam by mixing them up.
Skin type covers the first question. Fitzpatrick phototype covers the second. A client has both at the same time. A Type V client with oily skin gets a different treatment plan than a Type II client with oily skin, even though their skin type is identical, because their tolerance for peels, lasers, and sun exposure is not.
Key Exam Point: If a question asks about sebum, moisture, pore size, or breakouts, the answer is a skin type. If a question asks about burning, tanning, or pigment risk, the answer is a Fitzpatrick phototype. The two systems are not interchangeable.
The Six Skin Types
Skin types describe how the skin behaves on its own, before any product or treatment. They are based on sebaceous activity and the skin barrier. A client can shift between types over time with hormones, age, climate, and routine, but on the day of the analysis you classify what you see.
Normal
Balanced sebum and balanced moisture. Even tone, fine pores, no flaking, no shine, no obvious sensitivities. This is the textbook baseline and the type every other type is described in relation to. True normal skin is less common than students assume. If you are not sure between normal and combination, look closely at the T-zone in good lighting.
Dry (Alipic)
Low sebum production. The barrier function is weakened because there is not enough oil to seal moisture in. Dry skin can feel tight after cleansing, look dull, and show fine lines earlier. Pores are usually small and tight. The clinical term alipic means lacking lipids, which is exactly what is happening at the barrier level. Dry skin is a type, not a temporary state.
Oily
Overactive sebaceous glands. Visible shine in the T-zone and often across the cheeks within hours of cleansing. Larger pores, especially around the nose and mid-cheek. Prone to comedones (blackheads and whiteheads), and often to inflammatory breakouts because excess sebum mixes with dead cells inside the follicle. Oily skin tolerates active ingredients well, but the urge to overstrip it makes things worse.
Combination
Oily T-zone (forehead, nose, chin) with normal to dry cheeks. The most common skin type globally. The oil distribution follows the density of sebaceous glands, which is highest down the centerline of the face. Treatment requires zoning the routine, sometimes literally using one product on the cheeks and a different product on the T-zone.
Sensitive
Reactive skin with a compromised barrier. Easily flushed, may itch, burn, or sting with new products. Often shows visible redness, sometimes broken capillaries. Sensitive can overlap with any other type. A client can have oily sensitive skin or dry sensitive skin. The barrier is the issue, not the oil level. Treat it gently and rebuild the barrier before adding actives.
Mature
A descriptive type that overlaps with the others. Mature skin is shifting toward drier and thinner with reduced collagen, reduced elastin, and slower cell turnover. Fine lines, deeper expression lines, loss of firmness, more visible pigmentation from past sun exposure. Mature skin can still be oily in the T-zone, but the overall trajectory is toward dryness because oil production declines with age.
Dehydrated Is Not a Type, It Is a Condition
This is the single most tested distinction in skin analysis, and the answer that separates students who memorized from students who understood. Dry and dehydrated are not the same thing.
- Dry skin lacks oil. It is a type. The sebaceous glands underproduce. You cannot make a dry-typed client into a non-dry-typed client. You can only support the barrier and supplement lipids.
- Dehydrated skin lacks water. It is a condition. Any skin type can become dehydrated, including oily skin. Dehydration responds to hydrating ingredients, humectants, and lifestyle changes. It is reversible.
A common case: an oily-typed client comes in saying their skin feels tight and looks crepey when they smile. The student writes dry. The licensed esthetician writes oily, dehydrated. The treatment is hydration, not lipid replacement, and stripping cleansers caused the dehydration in the first place.
Common Mistake: Calling dehydrated skin dry on the intake form. Dry is a type, dehydrated is a condition. The exam will give you a question with both options listed and you have to pick the right one based on whether the prompt mentions oil or water.
The Fitzpatrick Phototypes
Dr. Thomas Fitzpatrick developed the Fitzpatrick scale in 1975 at Harvard to predict how a person would respond to UVA radiation, originally for dosing PUVA therapy. The scale runs from Type I to Type VI based on how the skin burns and tans after sun exposure. It is now the standard reference for laser, IPL, and chemical peel treatment planning.
Fitzpatrick is determined by interview as well as observation. Self-reported burning and tanning history matters because two people with similar visible skin tone can have different reactivity. The intake form should ask the client directly: in the first hour of unprotected sun exposure in early summer, do you burn? Do you tan?
| Type | Appearance | Sun Reaction | Common Features |
|---|---|---|---|
| I | Very fair, pale white | Always burns, never tans | Red or blonde hair, blue or green eyes, freckles |
| II | Fair | Burns easily, tans minimally | Light hair, light eyes |
| III | Medium, light olive | Burns moderately, tans gradually | Common in central and southern Europe |
| IV | Olive, light brown | Burns minimally, tans well | Mediterranean, Latin American, Middle Eastern |
| V | Brown | Rarely burns, tans easily and deeply | South Asian, Native American, some African |
| VI | Dark brown to black | Never burns, deeply pigmented | Sub-Saharan African |
The scale is about reactivity, not race. A South Asian client and a Mediterranean client might both fall at Type IV. Two siblings can land at different types. Always classify the client in front of you, never assume from background.
Why Fitzpatrick Matters in the Treatment Room
The whole reason an esthetics curriculum drills Fitzpatrick is treatment safety. Higher phototypes have more melanin, and melanin absorbs both light energy and the inflammatory aftermath of an aggressive treatment. The result of getting the phototype wrong is post-inflammatory hyperpigmentation (PIH), and in some cases burns or scarring.
Laser Hair Removal
Traditional laser hair removal targets the pigment in the hair follicle. It works best when there is high contrast between dark hair and light skin, which puts Type I to Type III in the safest zone for standard alexandrite or diode lasers. Type IV to Type VI carry a higher risk of burns and pigmentary changes with those wavelengths because the surrounding skin also absorbs the energy. The Nd:YAG laser, which has a longer wavelength that bypasses melanin in the epidermis, is the standard option for darker phototypes.
Chemical Peels
Light superficial peels (low percentage glycolic, mandelic, lactic) are generally safe across all phototypes. Medium and deep peels (Jessner, TCA, phenol) are higher risk on Type IV to Type VI because the inflammatory response can trigger PIH that lasts months. The general rule: as the phototype goes up, the depth of peel comes down, and pre-treatment with tyrosinase inhibitors becomes more important.
Intense Pulsed Light (IPL)
IPL uses a broad spectrum of light to treat pigmented and vascular lesions. Type I to Type III are generally safe. Type IV is borderline and requires conservative settings. Type V and Type VI are usually contraindicated for traditional IPL because the device cannot distinguish target pigment from background skin pigment. Newer devices have settings for darker skin, but the risk margin is narrow.
Sun Protection
Every phototype benefits from daily sun protection. Burn risk is highest in Type I to Type III, but the goal of sunscreen for Type IV to Type VI is not preventing burns so much as preventing pigmentary irregularity, melasma, and skin cancer. Skin cancer happens at every phototype, and it is often caught later in darker skin because clients and clinicians assume the risk is lower.
Clinical Tip: When you write a client chart, list both. Type II Fitzpatrick, normal skin with mild dehydration is a complete picture. Dry skin alone tells the next esthetician nothing about peel safety. Type IV alone tells them nothing about the routine.
Combining the Two in a Skin Analysis
A standard intake covers both classifications and a list of conditions on top of them. The order on most professional charts:
- Fitzpatrick phototype. Determined by interview (burning and tanning history) and observation. Set once and rarely changes.
- Skin type. Determined by observation under magnification, palpation, and a clean skin reading 30 minutes after cleansing. Reassessed periodically as it can shift.
- Conditions. Dehydration, sensitivity, breakouts, hyperpigmentation, redness, fine lines, broken capillaries. These are reversible or treatable states layered on top of the type and phototype.
This three-part chart is what the practical exam expects when you walk through a skin analysis with a model. Naming the Fitzpatrick type and the skin type and at least two conditions covers the analysis section completely.
What the State Board Tests
The most common exam questions in this section:
- Why is dry different from dehydrated? Dry lacks oil and is a type. Dehydrated lacks water and is a condition. Any type can be dehydrated.
- Which Fitzpatrick type always burns and never tans? Type I.
- Which type never burns? Type VI.
- Highest risk phototypes for post-inflammatory hyperpigmentation after a peel? Type IV, V, and VI.
- When is standard laser hair removal contraindicated? On darker phototypes (Type IV to VI) without a long-wavelength device like the Nd:YAG. Also contraindicated regardless of phototype on light, gray, white, or red hair, because there is not enough pigment in the follicle to target.
- Which skin type has overactive sebaceous glands? Oily.
- Which skin type is most common globally? Combination.
- What does alipic mean? Lacking lipids, the clinical term for dry skin.
How to Tell Them Apart on the Exam
If you are guessing on a multiple choice question, scan for the keywords:
- Words like sebum, oil, pores, breakouts, shine, tightness, comedones, barrier point to skin type.
- Words like burns, tans, UV, sun, melanin, phototype, laser safety, peel risk, PIH point to Fitzpatrick.
- Words like tightness with smiling, dull, lacks water, plumpness point to dehydration as a condition, not dry as a type.
- Numbers I through VI are Fitzpatrick. Words like normal, dry, oily, combination, sensitive, mature are skin types.
The two systems answer different questions, and a client always has both. Once that clicks, the section stops being confusing.
