Excessive hair growth stimulation
Chemical burns and allergic reaction
Chemical depilatories use strong alkaline agents that can cause chemical burns or allergic reactions if left on too long or used improperly. Patch testing is essential to avoid adverse effects. Clients with sensitive skin require milder formulas.
Which molecular weight range of hyaluronic acid is most effective for deep skin hydration?
Ultra-low molecular weight (<10 kDa)
High molecular weight (>1,000 kDa)
Low molecular weight (<50 kDa)
Medium molecular weight (100 - 300 kDa)
Medium molecular weight hyaluronic acid (100 - 300 kDa) penetrates the epidermis more effectively than high molecular weight but retains moisture better than low weight. This balance yields deeper hydration and skin plumping. Formulations often combine multiple weights.
During a chemical peel, which acid is classified as a medium-depth peeling agent?
Glycolic acid 20%
Salicylic acid 2%
Trichloroacetic acid 35 - 50%
Lactic acid 5%
Trichloroacetic acid in concentrations of 35 - 50% penetrates into the papillary dermis, classifying it as a medium-depth peel. It improves wrinkles and pigmentation but requires longer downtime. Lower concentrations cause superficial peeling.
In professional microdermabrasion, what is typically used as the abrasive agent?
Pumice powder
Aluminum oxide crystals
Microbeads
Oatmeal particles
Aluminum oxide crystals are standard in microdermabrasion to gently abrade the skin's surface and stimulate cell turnover. They are inert and uniform in particle size. Crystal flow is vacuumed away along with dead skin.
Which wavelength range is used by erbium:YAG lasers for skin resurfacing?
1064 nm
755 nm
532 nm
2940 nm
Erbium:YAG lasers operate at 2940 nm, which is highly absorbed by water in skin tissues, resulting in precise ablation with minimal thermal damage. They are ideal for fine lines and moderate resurfacing. Lower absorption lasers penetrate deeper but cause more heating.
What is the main difference between a true perm (acid wave) and an alkaline wave in hair treatments?
Acid waves use stronger heat, alkaline waves are cold
Acid waves only lighten hair, alkaline waves curl
Acid waves have a lower pH and are gentler, alkaline waves have higher pH and faster processing
Acid waves require neutralizer, alkaline waves do not
Acid (true) perms operate at lower pH (4.5 - 7), using heat and longer times for gentle texture. Alkaline perms (pH 8.2 - 9.6) process at room temperature faster but can be harsher. Both require neutralization to reform disulfide bonds.
In permanent hair color, what is the role of ammonia or its derivatives?
To oxidize pigments
To raise the hair cuticle and allow color penetration
To neutralize residual peroxide
To condition the hair
Ammonia or ethanolamine raises the pH of hair, opening the cuticle to allow color molecules and peroxide to enter the cortex. This ensures permanent pigment deposit. It also swells hair for better color uptake.
Which stabilizer is commonly added to hydrogen peroxide formulations to extend shelf life?
Sodium chloride
Potassium hydroxide
Sodium stannate
Calcium carbonate
Sodium stannate is often used to stabilize hydrogen peroxide, slowing its decomposition. This allows bleaching and disinfection products to remain effective longer. Stabilizers are crucial in cosmetic peroxide formulas.
What is the Cosmetology State Board regulation for disinfecting multi-use tools?
Wipe with a dry cloth
Immerse in EPA-registered disinfectant for the recommended contact time
Ultraviolet lamp exposure only
Wash with soap and water only
State boards require multi-use tools be cleaned of debris, then immersed in an EPA-registered disinfectant for the manufacturer's contact time. This practice prevents cross-contamination and infection. Wipes or UV alone are insufficient.
Which procedure requires a patch test 24 - 48 hours before full application?
Basic haircut
Manicure
Shampoo and blow-dry
Permanent hair color
Permanent hair color contains potential allergens like PPD that can cause severe reactions. A preliminary patch test 24 - 48 hours prior helps identify allergies. Barbers and stylists must perform and document this before coloring.
What is the recommended dilution ratio for a salon-grade disinfectant labeled as 1:256?
256 parts disinfectant to 1 part water
1 part disinfectant to 99 parts water
1 part disinfectant to 10 parts water
1 part disinfectant to 256 parts water
A 1:256 dilution means one part concentrate to 256 parts water, yielding the proper concentration for EPA-registered disinfection. Many quats and barbicide solutions use this ratio. Always measure precisely.
Which vitamin is essential for collagen synthesis in the skin?
Vitamin B12
Vitamin C
Vitamin A
Vitamin D
Vitamin C (ascorbic acid) is a cofactor in the hydroxylation of proline and lysine during collagen synthesis. It supports skin firmness and wound healing. Topical and dietary vitamin C improve collagen production.
Which advanced technique uses low-frequency ultrasound to enhance product penetration into the skin?
Microcurrent therapy
Cryotherapy
Ionophoresis
Photodynamic therapy
Ionophoresis uses a mild electrical current and low-frequency ultrasound to increase skin permeability, enhancing the delivery of active ingredients. It's used in medical and advanced spa treatments. Proper settings prevent irritation.
In perming, what is the significance of the rod's diameter relative to curl size?
Smaller rods produce larger curls
Rod diameter does not affect curl
Larger rods produce tighter curls
Smaller rods produce tighter, smaller curls
Perm rod diameter directly determines curl size: smaller rods yield tighter, smaller curls, while larger rods produce loose waves. Stylists select rod size based on desired texture. Proper tension and solution strength also matter.
Which advanced peel uses phenol to penetrate deeper into the reticular dermis?
Phenol-croton oil peel
Jessner's peel
Salicylic acid peel
Glycolic acid peel
Phenol-croton oil peels (Baker-Gordon formula) are deep peels that penetrate into the reticular dermis, offering dramatic results for wrinkles and scars. They require anesthesia and expose patients to higher risks. Post-peel care and cardiovascular monitoring are essential.
During a professional lash lift, which chemical breaks disulfide bonds to reform eyelashes into a lifted shape?
Glycolic acid
Salicylic acid
Hydrogen peroxide
Thioglycolate
Thioglycolate solution breaks the disulfide bonds in the lashes, allowing them to be reshaped around a silicone rod for a lifted effect. A neutralizer then reforms the bonds. Proper timing ensures curl without damage.

Cheat Sheet

  1. Skin Layer Fundamentals -

    Review the three main layers of skin - epidermis, dermis, and hypodermis - as outlined by the American Academy of Dermatology. Use the mnemonic "Come Let's Get Sun Burned" for the five epidermal strata (Corneum, Lucidum, Granulosum, Spinosum, Basale). Understanding this structure helps predict how treatments like exfoliation and chemical peels interact with each layer.

  2. Fitzpatrick Skin Type Scale -

    Memorize the Fitzpatrick Scale I - VI, a universal classification for skin's response to UV light (Fitzpatrick, 1975). Knowing your client's type guides safe SPF recommendations and laser settings; for example, Type I always burns, while Type VI rarely burns. This scale is essential in both skincare consultations and cosmetic laser protocols.

  3. Skin pH and Barrier Function -

    Healthy skin maintains a slightly acidic pH of 4.5 - 5.5 (University dermatology studies), crucial for barrier integrity and microbiome balance. Recall the pH formula, pH = - log₝₀[H❺], to track how acidic or alkaline products affect skin. Selecting cleansers and serums that match skin's natural pH minimizes irritation and supports optimal hydration.

  4. Makeup Color Theory -

    Learn the color wheel basics: primary (red, blue, yellow), secondary, and complementary colors to neutralize imperfections. For instance, green corrects redness and peach neutralizes dark circles, a principle used by professionals like Laura Mercier. Mastering this theory elevates contouring, color-correcting, and foundation matching skills.

  5. Sanitation vs. Disinfection Protocols -

    Differentiate sanitation (reducing microbes), disinfection (killing most pathogens), and sterilization (eliminating all microbes) per CDC guidelines. Always use EPA-registered disinfectants on tools and surfaces, following contact times listed on labels. A simple mnemonic "SDS: Sanitize, Disinfect, Sterilize" ensures you never skip a crucial step in client safety.
