Nowadays, it's natural to expect your coverage product to also have skin-care benefits, what with all the anti-aging, zit-zapping, and hydrating bases on the market. BB creams (and other double-lettered iterations) served as the driving force behind the recent barrage of multitasking products on the market — and they've quickly become mainstays on our top shelves.
For those unfamiliar with alphabet creams (or are still confused about what all those letters mean), here's a quick crash course: BB stands for "beauty balm" or "blemish balm" and BB creams are basically pumped-up versions of tinted moisturizers that usually include a nice amount of SPF. CC creams, on the other hand, offer hydration and SPF — like their BB counterparts — but add some color correction into the mix (hence, the CC).
DD creams are where it gets a little tricky, as many brands have different definitions for this category. Generally, DD creams tend to do "double duty" (and then some) — coverage, anti-aging, sun protection, etc. Now, are DD creams really that different from their double-lettered counterparts? It depends on the brand. Ultimately, you'll have to play around with the formulas to figure out which one makes the most sense for you and your needs — and not focus too much on their position in the alphabet.
