Ingredient callouts

A good concentration of Niacinamide (1.70% - 2.60%). 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.
Adenosine 0.10% - 0.45%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
An effective concentration of Panthenol (pro-vitamin B5) - about 1.20% - 1.90%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
Humectants (sodium hyaluronate 0.15% - 0.65%, panthenol 1.20% - 1.90% and glycerin 2.80% - 4.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

What can the product work for?

Evens skin tone

What does the product description say?

Niacinamide helps to even and improve the appearance of skin tone while moisture magnet Hyaluronic Acid helps skin retain moisture and appear plumped.

Source: Oh K!

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: 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 1.7% - 2.6%

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

Moisturizing

What does the product description say?

Niacinamide helps to even and improve the appearance of skin tone while moisture magnet Hyaluronic Acid helps skin retain moisture and appear plumped.

Source: Oh K!

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: glycerin, sodium hyaluronate.

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: chondrus crispus extract.

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

panthenol 1.2% - 1.9%

Irritation risk:

Concentration: Effectiveness: HIGH

Helps attract water to the upper layer of the skin and can help improve skin barrier function

chondrus crispus extract 1.1% - 1.6%

Irritation risk: Comedogenicity: High

Concentration: Effectiveness: HIGH

Red algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency

glycerin 2.8% - 4.2%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

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 1.7% - 2.6%

Irritation risk:

Concentration: Effectiveness: HIGH

Anti-aging

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

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 0.1% - 0.45%

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 1.7% - 2.6%

Irritation risk:

Concentration: Effectiveness: HIGH
