DE Esthetician study plan

Map the Delaware Board of Cosmetology and Barbering licensing framework for aestheticians: license tiers, renewal cycle, continuing education hours, and scope-of-practice boundaries, writing a one-page summary from primary-source statute and board rule text.

Define the infection-control vocabulary the exam uses (disinfection, sterilization, sanitation, hospital-grade disinfectant, bloodborne pathogen exposure incident) and write a plain-language definition for each from memory.

List the standard precautions sequence for a client service from hand hygiene through tool handling and waste disposal, then recite it aloud without notes.

Identify which implements in a typical facial setup are single-use versus reusable and state the required disinfection step for each reusable item.

Explain the layers and functions of the skin (epidermis, dermis, subcutaneous) and the role of the acid mantle and barrier function in client safety.

Compare skin types and conditions (dry, oily, combination, sensitive, dehydrated, acne-prone) and describe how each changes product selection and treatment intensity.

Describe the Fitzpatrick phototype scale and its practical use in deciding treatment parameters and contraindications.

Identify the anatomy of the hair follicle, sebaceous gland, and sweat gland well enough to explain how a facial treatment affects each.

Build a contraindication checklist covering pregnancy, active infection, recent chemical peel or laser, isotretinoin use, autoimmune conditions, and compromised skin, and state the safe action for each.

Explain the difference between a contraindication and a precaution and give two examples of each from esthetics practice.

Describe the signs of an allergic versus irritant reaction during a treatment and the immediate response steps for each.

Outline the client consultation and informed-consent process, including questions that must be asked before any exfoliation or extractions.

Sequence a complete basic facial from pre-service setup through cleansing, analysis, exfoliation, extractions, massage, mask, and finishing products, and justify the order of each step.

Describe safe extraction technique, including when to stop, and list the conditions under which extractions must be declined.

Explain the purpose and correct application of the main massage movements used in facial treatment and the areas to avoid.

Identify the categories of facial treatment devices and state one safety rule for each.

Classify the active ingredients commonly used in professional facials (alpha and beta hydroxy acids, retinoids, vitamin C, niacinamide, enzymes, azelaic acid) by function, typical concentration range, and key precaution.

Explain how pH and percentage jointly determine the strength of an acid exfoliant and why both matter for client safety.

Describe the chemistry of chemical peels at a level sufficient to explain superficial versus medium depth and the recovery expectations for each.

Identify ingredient combinations that should not be layered in one session and state the reason for each conflict.

Explain the regulatory categories that separate cosmetics from drugs and identify which claims push a product across that line.

Describe how to read an ingredient label, including order-of-concentration conventions, and spot misleading marketing claims.

Outline safe storage, labeling, and dispensing practices for professional products, including preservative and contamination concerns.

Summarize Delaware-specific rules on product labeling and record keeping that apply to an esthetics practice.

Recite the Delaware sanitation and safety requirements for the treatment room, implements, linens, and hand-washing facilities, and state the inspection consequences of noncompliance.

Describe the professional and legal obligations around client confidentiality, record retention, and scope-of-practice limits such as diagnosing skin disease.

Explain the correct response to a client who presents with a suspicious lesion, including what an aesthetician may and may not say.

Outline the business-practice essentials tested on the exam: record keeping, informed consent documentation, and insurance considerations.

Complete a full-length timed practice assessment and score each missed item by underlying concept rather than by topic label.

Re-teach the five weakest concepts aloud in under three minutes each, using your own examples.

Re-drill the infection-control, contraindication, and ingredient cards until each is recalled with no errors.

Build a one-page pre-exam review sheet limited to facts you have missed more than once.
