Skincare Fundamentals: A Science-Based Routine

Skincare advice online is mostly noise: 12-step routines, ingredient panic, and products sold on hype rather than evidence. This course strips it back to what actually matters — how your skin barrier works, why a short consistent routine beats a long inconsistent one, and what the research actually shows about the handful of ingredients that are genuinely well-studied.

Across eight lessons you'll learn how to identify your real skin type (and why it can change), how cleansing and moisturizing actually work at a biological level, why sunscreen is the single highest-leverage step in any routine, what retinoids/vitamin C/hyaluronic acid actually do and don't do, the basics of hair and nail health, and a debunking of the most common skincare myths that lead people to damage their own skin barrier chasing a trend.

No brand recommendations, no product pushing — just the underlying science so you can evaluate any product or claim yourself. Every lesson ends with flashcards and a Quick Check quiz, and a final exam ties the whole course together.
