Skin Science: Anatomy, Physiology, and Cosmetic Chemistry for Skin Care Professionals

This one-week, 40-hour online intensive previews the Aesthetics and Medical Aesthetics programs at Elite Royal International Career College. Students study the science underneath every skin care service: how the skin is built, how it protects and renews itself, how skin types and common conditions arise, how cosmetic ingredients work and are regulated in Canada, and how ultraviolet radiation damages skin and how sunscreens prevent that damage. The course is deliberately a science primer. Esthetic practice, treatments, and equipment are taught in the college’s full programs; this course builds the anatomical, physiological, and chemical understanding those programs assume, drawing on Health Canada, the Canadian Dermatology Association, the American Academy of Dermatology, and the standard dermatology and cosmetic science textbooks.

Who this course is for

Students considering a career as an esthetician or skin care therapist who want to know whether the science suits them before committing to a diploma, cosmetic and beauty retail associates who advise customers on products and want to understand ingredient labels properly, newcomers to Canada with beauty industry experience abroad who need the Canadian regulatory context, and anyone planning to move toward medical aesthetics, product formulation, or cosmetic sales.

What you will learn

• Day 1, Skin Anatomy. The three layers of the skin, the five strata of the epidermis, the dermis and hypodermis, the appendages, the cells that build and defend the skin (keratinocytes, melanocytes, Langerhans cells, and fibroblasts), the dermal matrix, the skin’s blood vessels and nerves, and how skin structure varies across the face and between people.
• Day 2, Skin Physiology. The barrier function of the stratum corneum, natural moisturizing factor, the acid mantle, sebum, cell turnover, the skin microbiome, the four phases of wound healing, intrinsic and extrinsic ageing, skin immunity and inflammation, how substances penetrate the skin, and the influence of hormones and lifestyle.
• Day 3, Skin Types, Conditions, and the Fitzpatrick Scale. Skin types versus skin conditions, Fitzpatrick phototypes, the mechanisms behind acne, rosacea, hyperpigmentation, and sensitivity, chronic inflammatory conditions, infections and infestations, skin cancers and benign growths, and the red flags that require referral to a physician or dermatologist.
• Day 4, Cosmetic Chemistry and Ingredients. INCI names, emulsions, emollients, humectants and occlusives, pH, exfoliating acids, retinoids, vitamin C, niacinamide, preservatives, patch testing, and the Health Canada framework that separates cosmetics, drugs, and natural health products.
• Day 5, Sun Science and Your Skin Science Career in Canada. UVA and UVB, SPF and broad spectrum protection, sunscreen regulation in Canada, Canadian Dermatology Association guidance, and the career paths that use skin science, including esthetics (NOC 63211), cosmetic sales, formulation, and medical aesthetics.

How the course works

Each day combines five core lessons, each followed by its own short quiz, two guided readings, Canadian context notes, and four or five hands-on labs. Every element is written and self-paced; no live session or video is required. The labs are paper and observation exercises that can be completed at home with ordinary products, a mirror, and free Government of Canada databases. The week closes with a final examination and a capstone project, the Skin Science Case File, in which students write a complete scientific assessment of one simulated client. Students who pass the quizzes and the final examination and submit the capstone receive the ERICC Certificate of Completion.

Where it leads

This primer is the recommended first step toward the college’s Aesthetics and Medical Aesthetics programs. It gives students the anatomy, physiology, and ingredient vocabulary those programs build on, so that practical training in treatments, equipment, and client care can begin from a secure scientific foundation.

Pricing and duration

Regular price $149.99, currently offered at a sale price of $99.99. Students receive 10 weeks of access to complete approximately 40 study hours at their own pace.
