Sure, you can always try to look for clues and pay attention to their skincare and makeup routines. Like, maybe they've mentioned a moisturizer that they're obsessed with (you can always buy

a complimentary product from the same brand). Or, maybe they're always sporting red lipstick, so you get them a new tube from a brand they've never used before.

But in case you haven't been paying attention a whole lot, I have a secret gifting trick for your beauty-lover friends: Get them a nice set of makeup brushes. Why? Well, everyone needs a set of quality makeup brushes, even for the person who's more skincare-oriented. Whether they use the set every day or occasionally, it will come in handy for smooth and flawless makeup application. The best part about a makeup brush gift set is that you don't really have to worry about the above preferences and it still feeds into their beauty obsession. It's foolproof, I tell ya.
