What the product description says
“Functional product for skin brightening and wrinkle improvement.”
Source: Yesstyle

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tripeptide-5.

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.

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.7–1.05%
Palmitoyl tripeptide-5Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.3–0.6%
Centella asiatica extractUnder-dosedA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.~0.25–0.45%

Works well
What the product description says
“This anti-aging essence effectively hydrates skin and restore its balance with a light texture.”
Source: Yesstyle

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": allantoin, betaine.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tripeptide-5, panthenol

Product summary

"iSOi - Intensive Treatment Essence" is effective for: Anti-aging and Moisturizing

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

Ingredient callouts

  • Peptides (palmitoyl tripeptide-5 0.30% - 0.60%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
  • Adenosine 0.70% - 1.05%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
  • An effective concentration of Panthenol (pro-vitamin B5) - about 1.60% - 1.90%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
  • In addition, this product contains Allantoin (1.10% - 1.30%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
  • Humectants (allantoin 1.10% - 1.30%, panthenol 1.60% - 1.90%, trehalose 1.90% - 2.30%, betaine 2.90% - 3.60% and glycerin 4.70% - 5.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
