Learn: Understand How Skin Works
Before you can care for your skin, you need to understand it.
This is where your journey begins — not with product promises or trends, but with the biology of your skin and how it behaves in the real world. Our Learn path is designed for beginners, the skincare-curious, or anyone who’s ever felt overwhelmed by conflicting advice.
We start with clarity. What is skin, really? What makes one skin type different from another? Why do your cheeks feel dry while your T-zone shines by noon? And what do “barrier repair,” “sensitive skin,” or “comedogenic” actually mean?
You don’t need a background in dermatology to make sense of skincare — but you do need the right lens. That’s what this path offers: a structured, science-grounded foundation that helps you observe your skin, understand its changing patterns, and decode what’s really going on beneath the surface.
Start Here: Foundations That Make Sense
If you’ve ever Googled a skin term and ended up more confused than when you started, this section is for you.
The Learn path is built to remove the noise. No trend-chasing. No jargon overload. Just straightforward answers to the questions that matter most when you’re starting your skincare education.
We’ll walk you through:
- What skin is made of, and how each layer contributes to its function
- Why “skin type” isn’t a fixed identity, but a fluid snapshot of how your skin behaves
- How internal and external factors influence your skin over time
- How to recognize patterns in your skin’s hydration, oil production, and reactivity
- What key terms — like barrier, pH, or sebaceous — really mean
Whether you’re just dipping a toe in or building a fresh foundation, this is where structured insight begins.
Skin First: What Is Skin, Really?
Most skincare conversations skip this part — but we don’t.
Skin isn’t just a surface. It’s an organ, and a highly intelligent one at that. From barrier protection to hydration balance, from pigment production to microbiome support, skin is in constant communication with your body and environment.
Understanding skin’s structure — the epidermis, dermis, and hypodermis — helps you decode why some products work, why others cause breakouts, and why no two people respond the same way to the same formula.
In the Skin Hub, we explore the biology behind the barrier:
- How the outer layer defends and regenerates
- What goes wrong when skin becomes reactive or dehydrated
- How aging, hormones, and environment shape the visible surface
- What role your microbiome, melanocytes, and sebaceous glands play

How Skin Types Are Decoded
Forget the magazine quizzes. Skin types aren’t boxes — they’re patterns. Your skin expresses these patterns based on biology, environment, and the way you care for it.
The familiar five — normal, dry, oily, combination, and sensitive — are a useful starting point. But they’re not the whole picture.
Real skin is layered, multi-zonal, and ever-changing. It shifts with hormones, climate, stress, diet, and even the time of day. It reacts — and it evolves.
That’s why Skincare Literacy™ teaches skin types as dynamic, not fixed.
Our framework builds on the traditional five and expands to seven — adding two types that are often misunderstood but crucial for making informed care choices:
- Acne-prone skin, which can overlap with oily skin but brings its own distinct care needs and care logic
- Dehydrated skin (not actually a type, rather a skin condition), which lacks water (not oil), and despite often being confused with dryness, it behaves differently than dry skin
These additions reflect the way real skin behaves — across zones, seasons, and stress levels — not just how it’s traditionally classified.
Why Seven Types?
We go beyond the traditional five to include acne-prone and dehydrated skin — because real skin doesn’t follow neat categories. It behaves. It shifts. We follow what it does, not just what it’s called.
The seven types aren’t marketing labels. They’re behavior-based categories — tools for observation and clarity. When you understand how these types show up in your skin, you gain the power to respond with care that actually fits.
You’ll learn how to
- Understand how skin types function as patterns, not labels
- Observe your skin’s zones and fluctuations over time
- Spot patterns of hydration, oil production, and reactivity
- Distinguish between overlapping types (like oily vs. acne-prone, and dry vs dehydrated
- Begin building skin logic that’s responsive, not reactive
We also introduce zone logic and skin type keywords, which will help guide your choices later on — from format selection to ingredient targeting, and active treatment planning later in your journey.

Glossary of Terms: Cut Through the Noise
Skincare terms can be confusing — and often misused. One of the biggest barriers to skincare literacy is the language used. What does “non-comedogenic” mean? What’s the difference between an emollient and an occlusive? Is pH balancing even a real thing?
Our glossary was created to answer these questions without dumbing anything down. It clears the air with short, science-backed definitions of the terms that matter. Every entry is evidence-based, clearly defined, and cross-referenced with our book and Skin Hub resources.
Start here any time something feels unclear — and bookmark it for future reference. More terms are coming soon.
Glossary Preview: What Does It All Mean?
Agents that promote exfoliation and soften keratin buildup, helping to unclog pores and reduce comedones.
A powerful depigmenting agent that inhibits melanin production. Effective for melasma and dark spots, typically used under medical supervision.
Mandelic acid is an alpha hydroxy acid (AHA) with a larger molecular weight. It penetrates the skin more slowly, offering gentle exfoliation suitable for sensitive or acne-prone skin.
Melano-competent skin has higher levels of melanin, providing better natural UV protection but potentially leading to reduced vitamin D synthesis.
The Four Skincare Pillars: Foundation for Smarter Care
Before you select products or layer treatments, it helps to understand the core functions of skincare. Skincare Literacy™ organizes these into four foundational pillars: Cleansing, Moisturizing, Sun Protection, and Treatment.
These aren’t steps in a fixed routine — they’re strategic tools. Each pillar connects directly to how your skin behaves. Once you understand their function, you can begin applying skincare logic that adapts to your skin’s real-time needs.
Learning to match the right pillar, at the right time, to the right skin behavior is the foundation of personalized care. Each pillar serves a distinct role — from maintaining barrier integrity to preventing damage and addressing specific skin goals. Each pillar also supports your skin differently — from removing buildup and protecting the barrier, to locking in hydration and addressing specific concerns like pigmentation, breakouts, or sensitivity.
Format Fundamentals: Why Texture and Delivery Matter
It’s not just what’s in your skincare — it’s how it’s delivered.
From light gels to rich balms, from watery essences to targeted serums, each format interacts with your skin differently. Texture affects absorption. Delivery systems influence how ingredients perform. And your skin’s needs change with the seasons, time of day, and skin state.
In this section, we explore:
- The main types of skincare formats (emulsions, serums, oils, gels, balms, etc.)
- How to spot format-function mismatches
- Why some formats work for one skin type but not another
- The difference between single-step and layered application logic
You’ll begin to connect format choice with both product intent and skin behavior — a key piece of skincare literacy that often gets overlooked.
We’re building out an interactive Format Navigator to help you match product textures to your skin logic — based on reactivity, hydration needs, and zone-specific behavior. For now, you’ll find early format insights inside the Skincare Pillars and Glossary.
Understanding format logic is a vital step toward responsive, personalized care — and a core part of what you’ll learn next.
Coming Soon
Our interactive Format Navigator is in development. For now, explore format insights inside the Glossary and Pillars pages.
Ingredient Categories: Make Sense of What’s Inside the Jar
If you’ve ever read a product label and wondered what any of it means, you’re not alone.
Besides cleansers, moisturizers, UV filters and active ingredients, there are also nine core functional categories of ingredients in skincare.
- Emulsifiers
- Solubilizers
- Preservatives
- Stabilizers/ pH buffers
- Thickeners/ Gelling agents
- Carriers/ Bases/ Solvents
- Antioxidants
- Fragrance and fragrance maskers
- Colorants
Understanding the roles of emulsifiers, thickeners, and stabilizers isn’t just for chemists. It’s how you decode claims, spot red flags, and understand why your skin loves or hates a certain product.
In a future Ingredient Library we will help you understand not just what’s in your skincare — but why it’s there — and whether it fits your skin’s current needs.
You’ll also start to recognize red flags, misleading claims, and ingredient patterns that match (or clash with) your skin behavior.
Coming Soon
A full Ingredient Library with logic-based filters is in development. Until then, you’ll find selected ingredient terms inside the Glossary and the skincare pillars.\
