# The Science

Skin Type PRO is built on a medically-published system designed to deliver precise, personalized skincare recommendations.

At the core of the platform is the **Baumann Skin Types** system, developed by dermatologist Dr. Leslie Baumann.

***

### Why This Matters

Most skincare recommendations are based on general skin categories like “dry,” “oily,” or “sensitive.”

These simplified approaches often lead to:

* Inconsistent results
* Trial-and-error product selection
* Poor patient adherence

***

💡 Skin Type PRO replaces guesswork with a structured, clinically grounded system.

***

### The Baumann Skin Types

The Baumann Skin Types system classifies skin into **16 unique skin types** based on four key parameters:

* Dry or Oily
* Sensitive or Resistant
* Pigmented or Non-Pigmented
* Wrinkle-Prone or Tight

***

{% hint style="info" %}
💡 This creates a more precise understanding of each patient’s skin and how it should be treated.
{% endhint %}

***

Each skin type requires a different approach to:

* Product selection
* Ingredient use
* Treatment strategy

For example, a dry and sensitive skin type requires a very different regimen than an oily and resistant skin type.
