What the product description says
“They help to reduce the appearance of lines and wrinkles, discoloration, enlarged pores and roughness through gentle exfoliation.”
Source: Neostrata

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

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

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.

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~4.3–5.3%
Lactobionic acidKey activeEffect: HighA polyhydroxy acid (PHA) that helps shed dead cells from the surface of the skin revealing a smoother, more even skin. PHAs tend to be gentler on the skin compared to AHAs (for example, glycolic acid). It also has hydrating properties and helps attract water to the upper layer of the skin. It can help calm down inflammation in skin and support restoration of the barrier function. It has an anti-oxidant effect as well. It can help reduce fine line, wrinkles and improve skin elasticity~0.9–1.1%
Palmitoyl tripeptide-8Key activeEffect: Medium~0.35–0.65%
Magnesium aluminum silicateEffect: LowMight be helpful in restoring skin barrier function and, when combined with zinc carbonate and malonic acid, reducing fine lines and wrinkles by stimulating elastin production. Also helps stabilize the product formulation~0.6–0.9%
Camellia sinensis leaf extractEffect: Low, below effective doseCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.3–0.6%
Zinc gluconateEffect: Low, below effective doseTypically used to stabilize the product formulations. It is a salt of a polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin.

What the product description says
“Gluconolactone strengthens the skin’s moisture barrier leaving it more resilient, while also providing potent antioxidant benefits.”
Source: Neostrata

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: arginine, dextran.

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: arginine, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: lactobionic acid, palmitoyl tripeptide-8

Lactobionic acidHeroEffect: HighA polyhydroxy acid (PHA) that helps shed dead cells from the surface of the skin revealing a smoother, more even skin. PHAs tend to be gentler on the skin compared to AHAs (for example, glycolic acid). It also has hydrating properties and helps attract water to the upper layer of the skin.

Source: Neostrata

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: gluconolactone, lactobionic 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
“6% PHA (Gluconolactone and Lactobionic Acid) Gluconolactone is found naturally in the skin and provides antiaging and gentle exfoliating benefits without sun sensitivity.”
Source: Neostrata

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, lactobionic acid.

This product contains antioxidants (lactobionic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - epilobium angustifolium flower/leaf/stem extract, gluconolactone also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Product summary

"NEOSTRATA - Redness Neutralizing Serum" is effective for: Anti-aging, Moisturizing, Evens skin tone and Exfoliation

Ingredient callouts

  • Exfoliating acids (). 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 (lactobionic acid 0.90% - 1.10% and gluconolactone 4.30% - 5.30%) 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 (palmitoyl tripeptide-8 0.35% - 0.65%). 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 (mannitol 0.25% - 0.40%, dextran 0.20% - 0.40% and arginine 1.90% - 2.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
