Key Benefits of Jack Black Line Smoother 8% Glycolic Acid Treatment

 
These are the key benefits you can expect from using Jack Black Line Smoother 8% Glycolic Acid Treatment:
 

🔵 Lightweight Moisturizer Suitable for Oily Skin

According to CreamScan analysis, Jack Black Line Smoother 8% Glycolic Acid Treatment is lightly moisturizing, with a moisturizing rating of 3.7 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 1.9 out of 10 and a moderate humectancy of 5.5 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula with a minimal amount of occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

💧  A Humectant Add-on for Any Skincare Routine

But it’s not limited to oily skin - since it contains a moderate amount of humectants, such a humectant add-on will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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: Jack Black Line Smoother 8% Glycolic Acid Treatment

 
CreamScan identified a few things to consider before adding Jack Black Line Smoother 8% Glycolic Acid Treatment to your skincare routine:
 

⚠️ May Increase Skin Photosensitivity Due to Glycolic Acid

This product contains glycolic acid, a popular AHA known for its ability to exfoliate and brighten the skin. Its action works by removing dead skin cells, revealing new, more delicate skin that is particularly vulnerable to sun damage.

As a result, using products with glycolic acid, regardless of concentration, may increase the skin's sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

To counteract this increased sun sensitivity, apply a broad-spectrum sunscreen with at least SPF 30 daily to protect your skin during glycolic acid treatment.

📌 Please always check the manufacturer's instructions for using the product, either on their website or product label.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Jack Black Line Smoother 8% Glycolic Acid Treatment is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Retinyl Palmitate, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Retinyl Palmitate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Retinyl Palmitate 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.

That said, there are some things about Jack Black Line Smoother 8% Glycolic Acid Treatment worth noting.
 
This product contains glycolic acid, a popular AHA known for its ability to exfoliate and brighten the skin. However, glycolic acid - regardless of concentration - can increase skin sensitivity, making it more prone to sunburn or irritation when exposed to UV rays. Therefore, it’s recommended to use a broad-spectrum sunscreen with at least SPF 30 during glycolic acid treatment.
 
If one of your main reasons for considering Jack Black Line Smoother 8% Glycolic Acid Treatment is its potential anti-aging effects, please note that, according to CreamScan analysis, its anti-wrinkle efficacy is questionable. None of the ingredients in this product provide substantial evidence of their anti-wrinkle efficacy according to CreamScan Research Evaluation Standards.
