“Micro-exfoliating LHA for precise cell-by-cell exfoliation to smooth roughness and gradually even skin texture.”
Source: Lookfantastic Australia

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: capryloyl salicylic acid.

Salicylic acidUnder-dosedEffect: HighUsed 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)~0.1–0.25%

What the product description says
“Efffaclar Mat is a mattifying daily face moisturizer for oily to acne-prone skin.”
Source: La Roche Posay Canada

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, zinc pca.

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: dimethicone, isocetyl stearate.

DimethiconeKey active· Emollient, OcclusiveEffect: HighA 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~1.8–2.2%
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~3.1–3.8%
Zinc pcaKey active· HumectantEffect: HighA compound that combines zinc with a hydrating ingredient PCA. Might to be helpful against acne and clogged pores. Can help calm down inflammation in skin. Could be helpful in reducing the formation of free radicals in skin. Might help to reduce fine lines in wrinkles, but solid evidence is missing~0.55–0.85%
Isocetyl stearateKey active· EmollientEffect: HighAn emollient that helps soften the skin~2.4–3%
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~5.3–6.5%
Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~0.6–0.9%
Isohexadecane· EmollientEffect: LowImproves the texture of the product and helps soften the skin. Helps oil and water mix together and can be used as a cleansing agent~0.6–0.85%
Cyclohexasiloxane· EmollientEffect: LowA silicone that serves as an emollient. Helps create a nice non-greasy feels~0.75–1.1%
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~0.15–0.3%

What the product description says
“Designed to fend off environmental aggressors, minimise the look of fine lines and keep excess shine at bay, this oil-free hydrator joins the Effaclar range as a must-try staple.”
Source: Cultbeauty

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - zinc pca - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

Zinc pcaEffect: LowA compound that combines zinc with a hydrating ingredient PCA. Might to be helpful against acne and clogged pores. Can help calm down inflammation in skin. Could be helpful in reducing the formation of free radicals in skin. Might help to reduce fine lines in wrinkles, but solid evidence is missing~0.55–0.85%
Ascorbyl glucosideUnder-dosedEffect: 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~0.3–0.6%
