Keep hearing about BB Creams? Another all-in-one product you can skip. Here is why:
I advise dividing skin products into two major groups. The first are ingredients to moisturize and treat. You can layer these one after the other; for example a facial oil followed by moisturizing gels, serums, lotions or creams. Then allow 10 minutes for absorption before using products from the second group; sunscreens and makeup. Group one products need to penetrate and reach deeper for best results, while group two are designed for the outermost layers of the skin. If they were combined, group two would keep group one from doing their job.
So although the convenience sounds good, it is a little like expecting a parfait of yogurt, granola and fresh fruit to be as good mixed up, stored in the fridge and served tomorrow as it is layered immediately before eating.
Note: If you like the look of a tinted moisturizer or BB cream, all is not lost when using them as your final layer. You still have gained the SPF, pigment (color) and the "finish" the product can offer. If further coverage is needed, just conceal and camouflage those areas. The look will still be overall more natural than using a high coverage foundation all over.
Primers: BB creams, tinted moisturizers or mineral SPFs can act as light diffusing primers and generally contain less silicone then most conventional makeup primers. Silicones lend the slippery smooth feeling but can cause some skin types to become clogged.
