OSNW Skin Type - Baumann Skin Typing System

The OSNW skin type is one of 16 unique skin types identified in the Baumann Skin Typing System, a dermatologist-developed skin typing system created by professor Leslie Baumann in 2005. If you have oily, sensitive, non-pigmented, and wrinkled skin, your Baumann skin type is OSNW.

With this skin type, you may struggle to correct signs of aging without unbalancing your oily, sensitive skin. In order to achieve this, it’s important to handpick gentle and lightweight products with a powerful filling and firming action.

This post is part of a series on the Baumann Skin Typing System, a dermatologist-developed skin typing system with 16 different skin types. If you are a OSNW skin type, keep reading; if not, take our quiz to find your unique skin type!

What is the Baumann Skin Typing System?

The Baumann Skin Type Indicator, or Baumann Skin Typing System, is a skin type classification system created by dermatology professor Leslie Baumann. It was first unveiled in the book “The Skin Type Solution”, published in 2005, and it’s since taken the world of beauty by storm.

Rather than rely on the traditional skin types we’re all familiar with (think dry, normal, or oily skin), the Baumann system is based around skin characteristics. According to Leslie Baumann, each person can be placed on either side of these four parameters, resulting in a unique skin type:

  1. Oily (O) versus Dry (D)
  2. Sensitive (S) versus Resistant (R)
  3. Pigmented (P) versus Nonpigmented (N)
  4. Wrinkled (W) versus Tight or Unwrinkled (T)

What are the 16 Baumann skin types?

In the table below, you will be able to find the 16 Baumann skin types, divided by the two characteristics that are often easier to identify: Oily (O) versus Dry (D) skin, and Sensitive (S) versus Resistant (R) skin:

The OSNW skin type: How to identify it

The OSNW skin type is oily, sensitive, non-pigmented, and wrinkled. Here’s what that means for you:


The main difference between oily and dry skin is the amount of sebum produced by the skin, which, in turn, can affect the skin’s moisture balance. Oily skin is the least problematic of the two, according to the Baumann system, but it’s still not without issue. The major complaints associated with oily skin include excess shine, dilated pores and, occasionally, the development of acne.


There are four unique subtypes of sensitive skin in the Baumann system: acne, rosacea, stinging, and allergic. The four subtypes can be useful when building pathology-centric skincare routines (especially for the acne and rosacea subtypes), but you don’t have to go that deep if you don’t want to.

The important thing to keep in mind is that inflammation is the common trait among the four subtypes of sensitive skin. Because of this, sensitive skin will typically require more complex care to tackle the source of inflammation without triggering further reactions.


This skin type doesn’t have any concerns associated with unwanted pigmentation–think dark spots and patches, melasma, or post-inflammatory hyperpigmentation (PIH). This is a great situation to be in, and you may want to put some effort into maintaining it. A good way to prevent the development of dark spots is to use sunscreen every day–even when it’s cloudy!


In the Baumann system, “Wrinkled” skin isn’t just affected by wrinkles; it’s also affected by other signs of aging, such as dullness, loss of elasticity and firmness, and just an overall “aged” and “tired” look. Skin aging is inevitable, but there’s still a lot you can do to minimize signs of aging if that’s a priority for you.

How to care for OSNW skin

If your skin type is OSNW, you have oily, sensitive, non-pigmented, and wrinkled skin. With this skin type, your greatest challenge is to figure out how to correct signs of aging without unbalancing your oily, sensitive skin.

  • A very high protection sunscreen with added anti-aging benefits.
