TL;DR
The esthetician written board exam covers skin anatomy, facial protocols, chemical exfoliants, hair removal, infection control, and state laws. Most exams have 100 questions with a 70-75% passing threshold. Prioritise skin anatomy and sanitation — they appear on every state exam.
Skin Anatomy: Memorise the Layers
Know the five layers of the epidermis from outermost to innermost: stratum corneum, stratum lucidum (palms/soles only), stratum granulosum, stratum spinosum, stratum basale (mitosis occurs here). The dermis contains collagen, elastin, sebaceous glands, sweat glands, hair follicles, nerves, and blood vessels.

Fitzpatrick Scale
The Fitzpatrick scale classifies skin types I-VI by response to sun exposure. Type I = always burns, never tans (very fair). Type VI = never burns, deeply pigmented. Darker Fitzpatrick types (IV-VI) have higher risk of post-inflammatory hyperpigmentation from peels and laser — critical for treatment planning questions.
Chemical Exfoliants
AHAs (glycolic, lactic, mandelic acid) are water-soluble and target the skin surface. BHAs (salicylic acid) are oil-soluble and penetrate pores — best for acne. Enzyme peels (papain, bromelain) digest dead cells without acid. TCA (trichloroacetic acid) is a medium-to-deep peel — above certain concentrations it falls outside esthetician scope of practice in most states.
Contraindications and Scope of Practice
Scope of practice questions are common. Estheticians cannot diagnose skin conditions, prescribe treatments, or perform procedures that penetrate beyond the epidermis in most states. When in doubt on an exam question, the answer is almost always: refer to a physician or dermatologist.
