Christina Aguilera, You are Beautiful and We Adore you! Just not your makeup artist! 

How-to avoid the dreadful "Cakeface"

 
-Moisturize your skin; having dry flaking skin is only going to be accentuated with makeup on top.

-This is obvious but please don’t pile on makeup!

-Bronzer should be used only in moderation.

-Accentuate one, maybe two features. Stay clear of accentuating your eyes, lips and cheeks as it starts to look like a clown.

- Cover only your imperfections with concealer such as Lipsi’s Camouflage, and set it with Aphrodite Powder, this will allow your natural glow to shine through while giving your face a flawless finish. Plus it feels amazing, light, airy and natural, this cakeface look doesn't exactly feel comfortable.
