What the product description says

Source: Soko Glam

Rosmarinus officinalis leaf extractEffect: MediumCan be helpful in reducing inflammation in skin, including inflamed acne. It can be irritating~1.5–2.2%

AllantoinEffect: Low, below effective doseHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.2–0.8%

Moisturizing

Side benefit · Glycerin, Sodium hyaluronate + 5 more

Works

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

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).

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.6–4%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.05–0.2%

Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~4.3–6.4%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.4–0.95%

Silybum marianum extractEffect: Low, below effective doseMight be able to help neutralize free radical, calm down inflammation in skin, and even skin tone~0.1–0.5%

Dipotassium glycyrrhizateUnder-dosedA salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening~0.35–0.75%

AllantoinUnder-dosedHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.2–0.8%
