Color Theory
Summary
Color theory forms the foundation of corrective and artistic makeup. Understanding the color wheel allows estheticians to neutralize unwanted tones, select flattering products, and correct discoloration effectively.
Primary Colors
• Red, Yellow, and Blue are the three primary colors
• They cannot be created by mixing other colors
• All other colors are derived from combinations of primaries
Complementary Colors
• Complementary colors are colors directly opposite each other on the color wheel
• When mixed or layered, they neutralize one another
• This is the scientific basis for color correcting in makeup
Color Correcting Reference Chart
| Skin Concern | Corrector Color | Why It Works |
|---|---|---|
| Redness / ruddy skin | Green | Opposite red on the color wheel |
| Dark purple/blue under-eye circles (medium–deep skin) | Orange or Peach | Opposite blue/purple on the color wheel |
| Yellow/sallow tones | Lavender or Purple | Opposite yellow on the color wheel |
| Dark spots / hyperpigmentation (fair skin) | Peach or Pink | Adds warmth and light to counteract darkness |
Undertones
• Warm undertones: yellow, peachy, or golden — best matched with warm-toned foundations
• Cool undertones: pink, red, or bluish — best matched with cool-toned foundations
• Neutral undertones: a mix of both warm and cool
Key Terms
• Primary colors – Red, yellow, blue; cannot be mixed from other colors
• Complementary colors – Colors opposite each other on the color wheel that neutralize one another
• Undertone – The subtle hue beneath the surface of the skin that influences foundation selection
• Color corrector – A pigmented product used to neutralize unwanted skin tones before foundation
⚠️ Watch Out For
• Do not confuse complementary colors (opposites that neutralize) with analogous colors (neighbors that harmonize)
• Orange correctors are for medium to deep skin tones; peach is for fair to medium skin tones — the exam may test this distinction
• Undertone is not the same as skin tone (depth/lightness); a client can be deep in skin tone but still have a warm or cool undertone

Product Knowledge
Summary
Knowing the characteristics, formulas, and appropriate uses of makeup products allows estheticians to select the right product for each client's skin type, concern, and desired outcome.
Foundation Types
| Formula | Coverage Level | Best For |
|---|---|---|
| Liquid | Light to full (varies) | Most skin types; versatile |
| Cream / High-pigment | Full coverage | Significant imperfections, stage/theatrical makeup |
| Powder | Light to medium | Oily skin; touch-ups |
| Mineral | Light to medium | Sensitive or post-procedure skin |
Powder Types
• Loose powder: finely milled, unpressed, lighter and more translucent — ideal for setting makeup
• Pressed powder: compacted into a pan, more portable and convenient — good for on-the-go touch-ups
Mineral Makeup
• Free of preservatives, fragrances, and synthetic dyes
• Less likely to cause irritation
• Suitable for sensitive skin and post-procedure skin (e.g., after facials or mild treatments)
Concealer
• Primary function: cover specific imperfections (dark circles, blemishes, discoloration) that foundation alone does not fully conceal
• Typically more pigmented than foundation
• Applied after foundation to target remaining trouble spots
SPF in Foundation
• SPF (Sun Protection Factor) measures UV radiation protection
• Foundations with SPF offer added UV protection for daily wear
• Important: Foundation with SPF is not a replacement for dedicated sunscreen — coverage is typically uneven and insufficient alone
Key Terms
• Full-coverage foundation – Maximum pigment formula; used for significant imperfections or stage makeup
• Loose powder – Finely milled, unpressed powder; offers translucent, lightweight finish
• Pressed powder – Compacted powder; portable; for touch-ups
• Mineral makeup – Formulated without preservatives/fragrances; ideal for sensitive/post-procedure skin
• SPF (Sun Protection Factor) – Measure of UV protection in a product
• Concealer – Highly pigmented product used to target specific imperfections
⚠️ Watch Out For
• The exam may ask which product is most appropriate for stage/theatrical makeup — the answer is full-coverage cream foundation
• Mineral makeup being "natural" does not automatically mean it has SPF — these are separate characteristics
• SPF in foundation does not replace sunscreen — know this distinction clearly

Application Techniques
Summary
Professional makeup application follows a specific sequence and employs targeted techniques to achieve a polished, long-lasting result that flatters the client's unique facial features.
Correct Order of Application
1. Primer – Prepares skin, fills pores, helps makeup adhere
2. Foundation – Creates an even base
3. Concealer – Targets specific imperfections
4. Setting Powder – Sets the look for longevity
Application Methods
• Stippling / Bouncing with a damp sponge (e.g., beauty blender): sheers out product and mimics natural skin texture for a seamless, natural finish
• Brush application: good for blending and building coverage
• Fingertip application: warms up product and allows precise placement
Contouring
• Uses a shade darker than the client's skin tone
• Creates the illusion of shadows and depth
• Sculpts and defines features: cheekbones, nose, jawline, forehead
• Paired with highlighting (lighter shade) for dimension
Blush Placement by Face Shape
| Face Shape | Blush Placement |
|---|---|
| Oval | Apples of cheeks, blended upward toward temples |
| Round | Higher on cheekbones, blended toward temples to elongate |
| Square | Apples and temples to soften angles |
| Heart | Apples of cheeks, blended horizontally |
| Oblong | Horizontally across cheeks to add width |
Baking
• Baking: applying a generous amount of translucent powder to areas (typically under-eye) and allowing it to sit for several minutes
• The heat from the skin sets the makeup underneath
• Dusted off to reveal a crease-free, brightened, long-lasting finish
Key Terms
• Primer – Prep product applied before foundation to smooth skin and extend wear
• Stippling – Pressing/bouncing technique with a sponge for a seamless foundation finish
• Contouring – Using a darker shade to create shadow and sculpt facial features
• Highlighting – Using a lighter shade to bring forward features and add brightness
• Baking – Setting translucent powder technique for long-lasting, crease-free finish
⚠️ Watch Out For
• Always remember: primer goes FIRST, before foundation — the order of application is frequently tested
• Contouring = darker shade (shadow); highlighting = lighter shade (not the same as a shimmer highlighter product)
• For the oval face shape, blush goes on the apples and up toward the temples — this is the standard "ideal" placement the board exam references

Skin Preparation & Client Assessment
Summary
A thorough skin assessment before makeup application ensures product compatibility, enhances performance, and protects the client's skin health.
Skin Type and Foundation Selection
| Skin Type | Recommended Foundation |
|---|---|
| Oily | Matte, oil-free, or powder formula |
| Dry | Hydrating, dewy, or liquid formula |
| Combination | Balanced formula; targeted application |
| Sensitive | Fragrance-free, mineral, or hypoallergenic formula |
| Normal | Most formulas are appropriate |
Pre-Makeup Skin Preparation Steps
1. Cleanse – Remove impurities, oil, and prior makeup
2. Tone – Balance pH and prep skin
3. Moisturize – Hydrate and protect the skin barrier
4. Prime – Create a smooth base, fill pores, extend wear
Why Assessment Matters
• Oily skin + heavy cream formula = breakdown and sliding
• Dry skin + matte/powder formula = cakey, flaky appearance
• Sensitive skin + fragranced products = irritation or reaction
• Proper assessment protects the client and ensures professional results
Key Terms
• Skin type – Oily, dry, combination, sensitive, or normal classification of skin behavior
• Primer – Applied post-moisturizer to prep skin for makeup adherence
• Matte finish – Non-reflective finish ideal for oily skin
• Dewy finish – Luminous, hydrated-looking finish ideal for dry skin
⚠️ Watch Out For
• Skipping moisturizer before a matte foundation on dry skin causes a cakey appearance — a common client complaint
• A client with sensitive skin should be directed toward mineral makeup or fragrance-free products
• Primer is not optional in a professional application — it is a standard preparatory step

Sanitation & Safety
Summary
Sanitation is among the most heavily tested areas on the California State Board Exam. Strict protocols prevent cross-contamination, protect clients from infection, and ensure compliance with California state regulations.
Mascara Protocol
• Disposable mascara wands must be used for each client and discarded after a single use
• Never double-dip into the mascara tube — this introduces bacteria
• Mascara tubes must never be shared between clients
• Risk: eye infections, including conjunctivitis (pink eye) and bacterial infections
Cream Products in Pots
• Never dip a brush or finger directly into the pot
• Use a clean, disposable spatula to transfer product onto a sanitized palette
• Load the brush or applicator from the palette only
• This prevents contamination of the original product
Makeup Brushes Between Clients
• Brushes must be cleaned and disinfected between every client
• Must use an EPA-registered disinfectant or hospital-grade disinfecting solution
• Single-use disposable applicators are recommended whenever possible
• Brushes that cannot be properly disinfected should not be reused
General Sanitation Principles
• Never share lip products, mascara, or eye applicators directly on clients
• Use disposable applicators (lip brushes, sponge-tip applicators, mascara wands) as standard practice
• Maintain a clean, organized, and sanitized workstation throughout the service
• Discard any product that has been contaminated
Key Terms
• EPA-registered disinfectant – A disinfecting solution approved by the Environmental Protection Agency for use on tools and surfaces
• Disposable applicator – Single-use tool discarded after one application on one client
• Sanitized palette – A clean surface used to hold dispensed makeup products during application
• Cross-contamination – Transfer of pathogens from one surface, product, or client to another
⚠️ Watch Out For
• The California Board exam heavily tests sanitation — never dipping directly into a pot is a key rule
• "Cleaned" brushes ≠ "disinfected" brushes — the board expects disinfection with an EPA-registered product, not just rinsing
• Mascara wands are always disposable — there is no acceptable disinfection protocol that makes a used wand reusable
• When in doubt on sanitation questions: disposable is always the safest answer
