Product Summary
"Oh K! - Illuminating Serum" is effective for: Anti-aging, Anti-blemish, Moisturizing and Evens skin tone
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.

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.

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
