A good concentration of Niacinamide (2.00% - 2.50%). 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.
Peptides (acetyl hexapeptide-8 0.20% - 0.35%). 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 0.45% - 0.65%. 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 1.20% - 1.40%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
Humectants (sodium hyaluronate crosspolymer 0.10% - 0.15%, hyaluronic acid 0.15% - 0.25%, sodium acetylated hyaluronate 0.15% - 0.30%, hydrolyzed hyaluronic acid 0.15% - 0.30%, acetyl hexapeptide-8 0.20% - 0.35%, sodium hyaluronate 0.25% - 0.45%, lactobacillus ferment 0.25% - 0.50%, sucrose 0.30% - 0.55%, hydrolyzed collagen 0.45% - 0.65%, panthenol 1.20% - 1.40%, betaine 1.40% - 1.70% and glycerin 2.50% - 3.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

What can the product work for?

Anti-aging

What does the product description say?

Low-Molecular Collagen(200 Da) – Infused with ultra-fine collagen peptides that work in synergy with PDRN to help improve skin firmness and elasticity.

Source: Amazon US

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

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

adenosine 0.45% - 0.65%

Irritation risk:

Concentration: Effectiveness: HIGH

Might 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)

niacinamide 2% - 2.5%

Irritation risk:

Concentration: Effectiveness: HIGH

Is 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

acetyl hexapeptide-8 0.2% - 0.35%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

Moisturizing

What does the product description say?

Intense Hydration & Revitalization – Deeply moisturizes while helping to smooth and energize dull, tired-looking skin.

Source: Amazon US

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: betaine, 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: hydrolyzed collagen, caprylyl glycol.

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

hydrolyzed collagen 0.45% - 0.65%

Irritation risk:

Concentration: Effectiveness: HIGH

A typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin

sodium hyaluronate 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Attracts water into the upper layer of the skin

hydrolyzed hyaluronic acid 0.15% - 0.3%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin

Anti-blemish

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

niacinamide 2% - 2.5%

Irritation risk:

Concentration: Effectiveness: HIGH

centella asiatica extract 0.3% - 0.55%

Irritation risk:

Concentration: Insufficient!

A 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.

allantoin 0.25% - 0.45%

Irritation risk:

Concentration: Insufficient!

Helps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated

Evens skin tone

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: alpha-arbutin, niacinamide

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.

niacinamide 2% - 2.5%

Irritation risk:

Concentration: Effectiveness: HIGH

alpha-arbutin 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: HIGH

Might help reduce hyperpigmentation when used regularly over a long period of time. Is more effective than beta-arbutin
