Anti-aging
Gluconolactone, Camellia sinensis leaf extract
Strong evidence
What the product description says
“If you're seeking an antiaging eye cream that also soothes and hydrates, look no further!”
Source: Neostrata

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

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~5.6–6.8%
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~0.3–0.55%
Exfoliation
Gluconolactone
Strong evidence
What the product description says
“4% Gluconolactone a Polyhydroxy Acid (PHA) that 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.

Moisturizing
Panthenol, Gluconolactone + 16 more
Strong evidence
What the product description says
“When applied topically, it acts as a moisture sponge to attract water and hydrates at the skin’s surface.”
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, 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: arginine, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

Evens skin tone
Not advertised by the brand · Gluconolactone, Camellia sinensis leaf extract
Strong evidence

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

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.
