vitamin C concentration

usually they already tell you on the packaging but if not you can ask the brand or search it

sometimes the brand says it on the name, you should contact them

Normally , at the packaging will tell you everything about how many the percent of the vitamin c , but if you nit get answered just simply DM the brand on the instagram or email instead . goodluck 🥰

you should ask the brand directly, sometimes there are some brands that don't list it.
