Product Summary
"Jack Black - Line Smoother 8% Glycolic Acid Treatment" is effective for: Anti-inflammatory, Anti-aging, Evens skin tone, Exfoliation and Moisturizing
Ingredient callouts
- Exfoliating acids (glycolic acid 6.40% - 7.90%). In this concentration, they will have a noticeable exfoliating effect. They can also have an anti-aging effect and stimulate collagen production in a long-run.
- This product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.45% - 0.65%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
- An effective concentration of Panthenol (pro-vitamin B5) - about 0.65% - 0.95%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
- Humectants (panthenol 0.65% - 0.95% and glycerin 3.90% - 4.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
Jack Black's Line Smoother 8% Glycolic Acid Treatment is fast-acting and smooths skin to help reduce the appearance of fine lines, wrinkles, and dark spots.
Source: Ulta
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains glycolic acid.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: vitis vinifera seed extract.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid
A plant extract that contains resveratrol and other anti-oxidant compounds that can help neutralize free radicals, reduce inflammation in skin and even out its tone. Can be also used to stabilize the product formulation
Might be helpful in restoring skin barrier function and, when combined with zinc carbonate and malonic acid, reducing fine lines and wrinkles by stimulating elastin production. Also helps stabilize the product formulation
Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Anti-oxidation
This product contains antioxidants (vitis vinifera seed extract) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
A plant extract that contains resveratrol and other anti-oxidant compounds that can help neutralize free radicals, reduce inflammation in skin and even out its tone. Can be also used to stabilize the product formulation
A plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals
A more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.
Evens skin tone
What does the product description say?

Source: Ulta
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: glycyrrhiza glabra root extract.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Exfoliation
This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: glycolic acid.

Moisturizing
What does the product description say?
Jack Black Line Smoother 8% Glycolic Acid Treatment hydrates dull, lackluster skin with nourishing botanicals to fight the visible signs of aging.

This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, propylene glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, dimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
Helps attract water to the upper layer of the skin and can help improve skin barrier function
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Enhances the product texture and makes it more spreadable. Helps reduce water loss from the outer layer of skin. Extands the shelf life by preventing bacteria growth
A non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together
Helps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating
Helps oil and water mix together and works as an emollient
An emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together
Improves the texture of the product and helps soften the skin. Helps oil and water mix together and can be used as a cleansing agent
Helps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
