What the product description says
“This new generation, one step skin resurfacing cream that gradually removes the dead, lifeless top layer of skin to reveal the younger looking skin beneath.”
Source: Mankind

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains glycolic acid.

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.

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~4.4–5.4%
Lactic acidUnder-dosedEffect: MediumAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.55–0.85%
Magnesium ascorbyl phosphateEffect: Low, below effective doseA derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high~0.3–0.5%

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.

“Gradually removes lifeless top layer of skinDeveloped to help treat the appearance of acne-scarringReduces pigmentation trouble areas”
Source: Mankind

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid

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.

What the product description says
“Gamma Hydroxy is a luxurious cream enriched with fruit acids to regenerate skin renewal, refine the skin’s texture and give the skin a new found radiance.”
Source: Lookfantastic

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, sodium hyaluronate.

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: phenyl trimethicone, cetyl alcohol.

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~0.75–1.1%
Phenyl trimethiconeKey active· OcclusiveEffect: HighA type of silicone that can decrease loss of moisture from the skin surface. It helps create a nice product texture~0.45–0.7%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.25–0.45%
Cetyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~1.7–2.1%
CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~2–2.5%
Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~0.55–0.85%
Cyclohexasiloxane· EmollientEffect: LowA silicone that serves as an emollient. Helps create a nice non-greasy feels~1.2–1.5%
Lactic acidUnder-dosedEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles.

What the product description says
“For oily skin, the inclusion of salicylic acid can improve blemishes by reducing the appearance of blackheads and white heads, whilst decongesting clogged pores penetrate the surface of the skin to deliver fantastic resurfacing benefits; reducing pore size and improving skin texture and colour, to reveal younger, healthier skin.”
Source: Lookfantastic

This product contains ingredients (glycolic acid) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.
