I credit 3B for improving my skin SO much. I only use things I get from the sub on my skin, for the most part, and somehow, even though they send a variety of brands, it all just really works for me. I don't think I'll ever go back to "American" skincare. I actually wish they would stop including the occasional makeup they do and just send exclusively skincare...which is a rarity for me, haha. (It's not that the makeup is bad, I just...do not need it.)
Anyway, I think it's definitely a good value for anyone interested in Korean/Asian skincare/beauty - The sizes are perfect for me and usually last the month until I get my next box and I love that usually, the boxes have a good variety of product types (cleanser, serum/essence, moisturizer, mask, etc).
