“Retinol Firming Moisturiser 0.2%A smoothing moisturiser with retinol that targets fine lines and blemishes, plus hyaluronic acid and vitamins C and E to hydrate and brighten.”

This product can help reduce breakouts and clogged pores because it contains the following ingredient: retinol. This ingredient is used for treating acne and can have a noticeable effect.

RetinolHeroEffect: HighTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating~0.15–0.7%
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~0.3–0.75%
Retinyl palmitateUnder-dosedThree 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~0.2–0.8%
Sodium ascorbyl phosphateUnder-dosedA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.1–0.35%

From product name

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ferulic 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.

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

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: ferulic 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.

“Regena-C Moisturiser M4 Pro with 3% Retinol Liposomes, Hyaluronic Acid and Vitamin C Mandarin Glass Jar”
From product name

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, hyaluronic acid.

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: butyrospermum parkii butter, oryza sativa bran oil.

Exfoliation
Side benefit · Retinol, Retinyl palmitate

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: retinol.
