Baumann Skin Type 6: OSNT

The OSNT Skin Type is Oily, Sensitive, Non-Pigmented, and Tight. The majority of people with this skin type are under the age of 30 with acne.

Sensitivity caused by underlying inflammation is the one barrier to skin health for OSNT types. However, using the proper acne treatment regimen for your skin type and anti-inflammatory ingredients can help you achieve a clear, acne-free complexion.

What Are the Benefits of Having the OSNT Skin Type?

With only one barrier to skin health, OSNTs have quite a few benefits. Dryness and dehydration and not typically a concern for this type, as your skin produces adequate sebum (oil) to maintain a healthy skin barrier that locks in moisture and keeps irritants seal out.

OSNTs do not have pigmentation problems such as dark spots, uneven skin tone, or conditions like melasma or post-inflammatory hyperpigmentation.

Because this skin type tends to be younger or have practiced excellent sun protection habits, it tends to have a smooth, wrinkle-free complexion.

Wearing daily sunscreen and maintaining those healthy lifestyle habits will help you to continue to stave off signs of advanced aging.

What Are the Cons of Having the OSNT Skin Type?

The main skin concern that OSNT types have is inflammation, which often leads to acne. Inflammation can be caused by the C. acnes bacteria that causes acne or hormone fluctuations, which can also lead to acne.

Benzoyl peroxide

Lavender oil

Some recommended products for OSNT skin type

What Types of Products Should OSNT Skin Types Use?

OSNT skin types should use a foaming and/or salicylic acid cleanser to help control excessive oil and acne.

Anti-inflammatory treatment products can be used to calm redness and irritation. Many oily skin types do not need to moisturize twice per day. If your skin is very oily, you may be able to skip your morning moisturizer and replace it with a non-comedogenic (meaning it won’t clog pores) sunscreen.

In the evening, you can use a light moisturizer that does not contain comedogenic ingredients.

What Types of Products Should OSNT Skin Types Avoid?

Oily skin types like OSNTs should avoid using products that contain comedogenic ingredients that are known to clog pores.

Heavy moisturizers should be avoided, as your skin already produces enough sebum to maintain a healthy skin barrier.

What Cosmetic Procedures Are Good for OSNT Skin Types?

OSNTs often benefit from salicylic acid peels, facial extractions, and HydraFacials to help manage acne. Blue light and lasers may also be effective acne treatment options for this skin type.

OSNTs with a rosacea subtype may benefit from IPL treatments to improve the appearance of visible blood vessels and redness.

Oily, Sensitive, Non-Pigmented and Tight Skin Type

Taking steps to eliminate sources of inflammation, which can include acne-causing bacteria, hormones, and irritating skin care ingredients, will help OSNT skin types manage and prevent acne breakouts.

The good news is that other barriers to skin health are nonexistent in this skin type, so OSNTs can focus on treating inflammation to achieve a clear, healthy complexion.
