What the product description says

“diminishing the look of fine lines and wrinkles”

Source: Sephora

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: hexanoyl dipeptide-3 norleucine acetate.

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~3.1–3.8%

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~2.3–2.8%

GluconolactoneKey activeEffect: HighA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~1.1–1.3%

Hexanoyl dipeptide-3 norleucine acetateKey activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.25–0.45%

Glucosamine hclEffect: LowMight be able to stimulate production of skin's natural moisturizing compounds such as hyaluronic acid. Could be helpful for evening the skin tone.~1.4–1.7%

Algae extractEffect: LowPlant extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but research is not extensive yet~0.75–1.1%

Lycium barbarum fruit extractEffect: Low, below effective doseA plant extract that can help neutralize free radicals in skin and attract water to its upper layer~0.35–0.6%

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~0.25–0.45%

Phyllanthus emblica fruit extractEffect: Low, below effective doseA plant extract that might be helpful in neutralizing free radicals and have a skin lightening effect if used in high enough concentrations~0.1–0.2%

What the product description says

“Multi-Acid Resurfacing Pads”

Source: Sephora

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: gluconolactone, glycolic acid, salicylic acid.

Salicylic acidKey activeEffect: 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)~1.6–2%

UreaKey activeEffect: MediumNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~0.55–0.8%

What the product description says

“moisturizing”

Source: Sephora

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: algae extract, glucosamine hcl.

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: algae extract, glycine soja oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: hexanoyl dipeptide-3 norleucine acetate, niacinamide, urea

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

What the product description says

“evens skin, lightens dark spots”

Source: Sephora

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: gluconolactone, glycolic acid, niacinamide, salicylic 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: glucosamine hcl.

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.

Product summary

This product could be helpful for: Anti-oxidation, but its actives are not the most effective or are not well-studied.

Ingredient callouts

A good concentration of Niacinamide (2.30% - 2.80%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
Exfoliating acids (glycolic acid 3.10% - 3.80%). 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. PHAs (gluconolactone 1.10% - 1.30%) in this product also work for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
Peptides (hexanoyl dipeptide-3 norleucine acetate 0.25% - 0.45%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
Salicylic acid (1.60% - 2.00%). This is an oil-soluble exfoliating acid. Because of this property, it can work inside pores and help reduce the congestion. It has an anti-inflammatory effect and is used to treat acne. Because it is a quite strong exfoliator, be careful with using this product too often: it could result in over-exfoliation.
Humectants (urea 0.55% - 0.80%, sodium hyaluronate 0.20% - 0.40%, yeast extract 0.80% - 1.20%, glycerin 0.45% - 0.65%, glucosamine hcl 1.40% - 1.70% and algae extract 0.75% - 1.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
