Ingredient callouts
- A good concentration of Niacinamide (2.70% - 4.00%). 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.
- Humectants (sodium hyaluronate 0.35% - 0.80%, panthenol 0.30% - 0.70% and arginine 1.10% - 1.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

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: betaine salicylate.

Moisturizing
What does the product description say?
This product helps remove excess sebum and blackheads so you can find healthy and hydrated skin. p H 4.85~1.0. Vegan and Cruelty-free.
Source: Soko Glam
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, 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: arginine.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, panthenol
