What the product description says
“Men's Acne Barrier Protect Lotion”
From product name

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": dipotassium glycyrrhizate, butylene glycol.

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).

Dipotassium glycyrrhizateKey active· HumectantEffect: HighA 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~4.8–7.2%
Hydrogenated castor oilKey active· EmollientEffect: MediumA plant oil that can help soften the skin. It might be helpful in calming down inflammation, but solid research is lacking. Is often used in lip products to create the needed product consistency~1.4–2%
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~2.8–4.2%
