When you run out of your favorite ingredients🥲

I have one favorite ingredient for my mature skin. It’s Red Ginseng . I used : DONGINBI Red Ginseng Daily Defense Essence EX. I won giveaway. The price is expensive. So when i run it out, i am like..what will i do..😀😀 i hope anyone in here will give me some suggestions. Maybe about other brands with same or similar ingredients. And hopefully cheaper. Thank you 😊
