I also tend to have a problem during the winter season. My lips get really dry, so I need a lip product that won't dry them out further. Finding something that is pretty and nourishes my lips, is almost impossible.
That said, I found my latest favorite that has a permanent spot in my purse. Maybelline's Color Whisper lipstick is amazing! I've been seeing a lot of tinted balms and glosses, but this stuff is seriously the best.
It's a gel-based lipstick that adds a very sheer layer of color (you can also go for the boldest hue because it is so sheer that it simply looks natural). Most lipsticks are made with a ton of wax and other stuff that is quite drying. Because this product is mostly gel, it makes lips look gorgeous and healthy.
I can't find most of the colors online--they're fairly popular and sold out. But, I did see them in a few different drugstores, so they are around!
The best part? Each lipstick retails for under $8.
