Key Benefits of MAC Cosmetics Studio Fix 24-Hour Smooth Wear Concealer Nc50

 
These are the key benefits you can expect from using MAC Cosmetics Studio Fix 24-Hour Smooth Wear Concealer Nc50:
 

🔵🔵 Well-Suited Moisturizer for Normal to Dry Skin

According to CreamScan analysis, MAC Cosmetics Studio Fix 24-Hour Smooth Wear Concealer Nc50 is highly moisturizing, with a moisturizing rating of 7.5 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of humectancy and occlusivity: a high humectancy of 7.5 out of 10, primarily due to the substantial concentration of Butylene Glycol (est. ≈6.0%), and a high occlusivity of 7.5 out of 10, mainly due to the significant content of Trimethylsiloxysilicate (est. ≈11.0%) and Tribehenin (est. ≈2.0%).

This type of moisturizer is well-suited for people with normal skin who want significant hydration in a rich yet not overly thick formula. It combines a significant amount of humectants and occlusive ingredients to provide effective dual-action moisturizing.

The product’s occlusive profile suggests a texture that is rich and creamy but not overly thick, offering the potential to absorb into the skin without leaving a greasy afterfeel in most cases.

This product may also be a good choice for people with dry (but not very dry) skin for daily hydration, as it strikes a balance between significant moisturizing potential and a texture that is not too thick.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: MAC Cosmetics Studio Fix 24-Hour Smooth Wear Concealer Nc50

 
CreamScan identified a few things to consider before adding MAC Cosmetics Studio Fix 24-Hour Smooth Wear Concealer Nc50 to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing MAC Cosmetics Studio Fix 24-Hour Smooth Wear Concealer Nc50 is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Olea Europaea (Olive) Leaf Extract, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Olea Europaea (Olive) Leaf Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Olea Europaea (Olive) Leaf Extract may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

Therefore, this ingredient does not generate the anti-wrinkle rating.

📌 Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.
