Tips + AdviceToner vs. essence vs. serum: do you need all three?Three bottles, three names, and no rule that says you need all of them. Read the categories as marketing language and choose by formula instead.
The Baegayul Journal
Plainspoken notes from Dr. Jo on reactive skin, Korean botanical knowledge, and the philosophy behind Baegayul.
Tips + AdviceToner vs. essence vs. serum: do you need all three?
Ingredient LogGlycerin vs. hyaluronic acid: do you need to choose?Two different ingredients with a shared hydration role, often listed in the same bottle. Read the names for what they are, then judge the finished formula.
Ingredient LogBetaine vs. betaine salicylate: the full name mattersOne 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 LogCica, 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 LogCan 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.
Tips + AdviceSheet mask vs. sleeping mask: follow the format, not the nameBoth are called masks, but one is removed after a set time and the other is usually left on overnight. The word does not make their directions interchangeable.
