What You’ll Find Inside: A Book Built to Teach and Compare

Skin Types Decoded is structured in 13 parts and 83 chapters, offering a balance between science, application, and personalization. Each part builds towards a fuller understanding of how skin behaves—and how to care for it in a way that is precise, intentional, and responsive. Together, they form a cohesive learning journey grounded in science and shaped by real-world application.

Part 1 – Rethinking Skincare: Why Skincare Feels so Confusing

We begin by rethinking modern skincare—how we got here, why there’s so much confusion, and what it really means to “know your skin.” This part sets the tone and purpose of the book: to replace noise with clarity and to connect the dots between skin structure, skin types, and skincare.

Part 2 – Skin Structure: How Skin Works

This is the foundation. You’ll explore the epidermis, dermis, and hypodermis—and how each layer influences hydration, sensitivity, pigmentation, aging, and barrier function. Without understanding structure, choosing the right skincare is guesswork.

Part 3 – Skin Types: Understanding Your Skin’s Behavior

Skin types aren’t fixed—they’re dynamic. This part introduces a physiology-based framework for understanding sebum, hydration, and reactivity. It builds on traditional categories and explains why your skin can shift over time and across zones.

Part 4 – Skincare Pillars and Formats: Strategy, Not Just Products

Cleansers, moisturizers, sunscreens, and treatments form the four skincare pillars. This part explains how they work, how formats affect delivery and feel, and how ingredients interact with the skin. This is where structure meets care.

Parts 5–10: The Six Foundational Skin Types

Each of these parts focuses on one of the six foundational types:

  • Part 5 – Normal Skin
  • Part 6 – Dry Skin
  • Part 7 – Oily Skin
  • Part 8 – Acne-Prone Skin
  • Part 9 – Sensitive Skin
  • Part 10 – Combination Skin

Each part follows the same logical structure—so you can learn, apply, and compare across skin types. You’ll find:

  • Traits and behaviors
  • Skincare priorities and challenges
  • Format and ingredient guidance
  • A personal story to bring the skin type to life
    You can start with the part that feels most relevant or explore all six to better understand the spectrum.

Because each skin type part follows the same framework, you can compare types side-by-side. Whether your skin is clearly defined or sits between categories, this book helps you build your own roadmap.

Part 11– Dehydrated Skin: The Great Imitator

Dehydrated skin isn’t a type—it’s a condition that mimics both dryness and sensitivity, often leading to product mismatches. This part explains how to spot it, why it overlaps with other types, and what to do about it.

Part 12– Reading the Skin Type Spectrum

This synthesis section ties everything together. It introduces a spectrum model and a format model that show how skin types flow into each other and how skincare can be both adaptable and intentional.

Part 13– Final Thoughts: Skin Literacy in Real Life

The book closes with a personal message: how to observe your skin with clarity, how to keep learning, and how to move forward in your skincare journey with confidence. Skin literacy is a practice—not a prescription.

Take It With You: The Perfect Companion for Real Life

Whether you’re shopping at a drugstore, browsing a department store, or scrolling your favorite online shop, this book is built to travel with you.

  • Use it to decode product labels
  • Match ingredients to your skin’s real needs
  • Avoid overhyped but misaligned purchases

Pro tip: Start a skin journal or skin diary. Your skin can shift with seasons, travel, hormones, stress, or age. Observing your skin over time helps you personalize your care and catch changes early. You can care for your skin on its own terms.
