CO Esthetician study guide
CO Esthetician · Work through your exam, one topic at a time.
The Colorado esthetician license is the credential the state requires before you may legally perform skin care services for compensation - facials, cleansing and exfoliation, massage, waxing and other hair removal, makeup application, and brow and lash services. It is administered under the Colorado Office of Barber and Cosmetologist Licensing, part of the Division of Professions and Occupations. The CO Esthetician study guide has 8 sections and about 3,096 words.
01Sanitation, Disinfection, and Safety Practices
Sanitation, disinfection, and safety is the domain that separates a licensed esthetician from an unlicensed operator. The Colorado exam tests how you classify implements, select an EPA-registered product, follow contact time, and respond to spills and injuries without improvising.
428 words, about 2 min02Skin Anatomy, Physiology, and Histology
Skin anatomy, physiology, and histology is the domain that explains why products behave as they do. The Colorado exam tests the layers of skin, the cells and appendages in each, the barrier and acid mantle, and the difference between epidermis and dermis when a product or lesion is discussed.
396 words, about 2 min03Skin Analysis, Conditions, and Disorders
Skin analysis, conditions, and disorders tests whether you can look at a face, separate what is stable from what is changeable, name lesions correctly, and refer what is outside your scope. Colorado expects estheticians to recognize disease, not diagnose it.
371 words, about 2 min04Facial Treatments, Cleansing, Exfoliation, and Massage
Facial treatments, cleansing, exfoliation, and massage is the practical heart of esthetics. The exam tests the order of a service, which cleanser and exfoliant fit which skin, how to extract safely, and when massage is contraindicated.
391 words, about 2 min05Hair Removal (Waxing and Related Methods)
Hair removal tests the hair-growth cycle, product technique, and contraindications. Waxing, sugaring, threading, and depilatories all remove hair temporarily; the exam asks which method fits the area and when you must refuse.
409 words, about 2 min06Makeup Application and Brow/Lash Services
Makeup application and brow/lash services tests color theory, foundation matching, sanitation with shared products, and the boundaries of eye-area services. Undertone is cool (pink/blue), warm (yellow/golden), or neutral.
367 words, about 2 min07Chemistry, Products, and Ingredient Knowledge
Chemistry, products, and ingredient knowledge tests whether you understand pH, formulation, and interactions well enough to choose and combine products safely. Skin's acid mantle is about pH 4.5–5.5.
352 words, about 2 min08Colorado Laws, Rules, and Professional Ethics
Colorado laws, rules, and professional ethics tests the Barber and Cosmetology Act, licensing, scope of practice, and the standards that keep a license defensible.
