What the product description says

“Powerful peptides and Hyaluronic Acid help promote collagen synthesis and plump the dermis for smoother, firmer-looking skin.”

Source: Skinstore

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: carnosine, glycerin.

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: glycine soja oil, vegetable oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, palmitoyl hexapeptide-14, panthenol, urea

Acetyl hexapeptide-8Hero· HumectantEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~4.5–5.5%

UreaHero· HumectantEffect: HighNaturally 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~2.3–2.8%

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.5–0.75%

Palmitoyl hexapeptide-14HeroEffect: High~0.2–0.35%

Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.25–0.45%

What the product description says

“Combat aging with this potent grouping of antioxidants.Who is this for?Ideal for those with aging skin who want smoother, firmer and more even-toned skin.”

Source: SkincareRX

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, carnosine, palmitoyl hexapeptide-14, resveratrol.

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.

Ascorbic acidHeroEffect: HighThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~6.1–7.4%

What the product description says

“Combat aging with this potent grouping of antioxidants.Who is this for?Ideal for those with aging skin who want smoother, firmer and more even-toned skin.”

Source: SkincareRX

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

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.

Ingredient callouts

This product also contains Vitamin C (Ascorbic Acid) 6.10% - 7.40% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
Peptides (palmitoyl hexapeptide-14 0.20% - 0.35% and acetyl hexapeptide-8 4.50% - 5.50%). 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.
Humectants (hydrolyzed hyaluronic acid 0.20% - 0.40%, carnosine 0.30% - 0.60%, glycerin 0.50% - 0.75%, panthenol 0.50% - 0.75%, urea 2.30% - 2.80% and acetyl hexapeptide-8 4.50% - 5.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
