What the gurus are saying

Birch sap in this lotion works like a natural salicylic acid, and reviewers especially recommend it for normal to oily, acne-prone skin, with its lightweight formula adding to the appeal. It also includes terpineol, a tea tree oil constituent that provides antibacterial benefits without the heavier profile of full tea tree oil. Those with dry skin may find it too lightweight for their needs.

"Besides that a very old classic Cosrx Oil Free Ultra Moisturizing Lotion which has birch sap in it. Birch sap is basically a natural form it works like salicylic acid."

"This really might be a perfect moisturizer for normal to oily acne prone skin. They start with a hydrating birch base and added in the [4-terpineol] ingredient, one of the active constituents found in tea tree oil, which may give antibacterial benefits without the full tea tree oil profile. It's more unique than it sounded to me on the surface."

"COSRX has an oil-free moisturizing lotion that looks good."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
