What the product description says
“L’Oreal Paris 5% Glycolic Acid Peeling Toner”
Source: Lookfantastic

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.

Glycolic acidKey activeEffect: HighAn 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~5.6–8.4%
Hydroxyethylpiperazine ethane sulfonic acidKey activeEffect: MediumUsed to regulate product's pH, but can be also used as an exfoliator when included in higher concentrations. There is a controversy about whether it can generate free radicals and induce skin cell damage when used in topical products~3.7–5.6%
Salicylic acidUnder-dosedUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~0.1–0.3%
Moisturizing
Side benefit · Panthenol, Glycerin + 4 more
Works well

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, bis-peg-18 methyl ether dimethyl silane.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.5–1.2%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.7–4.1%

Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally 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~1.3–1.9%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.35–0.8%
Evens skin tone
Side benefit · Glycolic acid, Ascorbyl glucoside + 1 more
Works well

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: ascorbyl glucoside.

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.

Glycolic acidKey activeEffect: HighAn 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~5.6–8.4%
Ascorbyl glucosideKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~0.85–1.25%
Salicylic acidEffect: Low, below effective doseUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~0.1–0.3%
Anti-aging
Side benefit · Glycolic acid, Ascorbyl glucoside + 2 more
Works well

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: ascorbyl glucoside.

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.

Side benefit · Ascorbyl glucoside, Citrullus lanatus fruit extract + 1 more
May help

This product contains antioxidants (ascorbyl glucoside) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
