Want to save time in the morning while also saving counter space? Let's be real, who doesn't? Thanks to BB creams, you can. You might be wondering: what is BB cream really? According to WebMD, BB cream, also known as beauty or blemish balms, promise to do the job of five or six other jars and tubes: moisturizer, primer, sunscreen, skin treatment, concealer, and foundation. A quality BB cream can disguise bags, blemishes, redness, and dark circles. It can make a tired face instantly look fresh.
