In this course, you’ll learn how the skin works and why it matters in medical aesthetics. We’ll look at the layers of the skin and what each one does to protect, heal, and keep skin healthy. You’ll also learn about oil glands, sweat glands, and pores, and how they affect things like shine, dryness, breakouts, and skin texture. We’ll introduce veins and blood circulation in a simple way so you understand how blood flow brings oxygen and nutrients to the skin and helps it stay vibrant and strong.
