The Baegayul Journal

Plainspoken notes from Dr. Jo on reactive skin, Korean botanical knowledge, and the philosophy behind Baegayul.

Ingredient Log Betaine vs. betaine salicylate: the full name matters

One word of difference changes the listed function. Betaine is a humectant name; betaine salicylate is a keratolytic name. Read the complete ingredient name before drawing a conclusion.

Ingredient Log Cica, Centella asiatica and madecassoside: what is the difference?

A nickname, a plant and a compound. The three words are related, but they are not interchangeable ingredient declarations, and only the ingredient list tells you which one a formula uses.

Ingredient Log Can you tell ingredient percentages from a skincare label?

Not reliably. Order gives some information about relative amounts in the United States, but the 1% exception and other rules mean a label is not a formula sheet.
