The secret to making your face look thinner with makeup is contouring, enhancing the angles in your face. Here are a couple easy tips for those who have a round face and want to make it look slimmer.
*While applying blush smile and apply it to the front of your cheeks. This will make your face look thinner.
* Contour cheeks by applying pale brown face powder or bronzer (no shimmer!) in the hollows of your cheeks. Try making a fish face to better see where to apply. This trick will create a light shadow effect that will bring out your cheek bones and make your face look slimmer.
* Another trick I came accross online is to use 2 (or even 3) shades of blush to contour your cheeks. One light shade is applied in circular motions on the apples of your cheeks and the deeper shade is applied just below the cheekbones. Blend well! I have not tried this trick yet, so if you have, please let me know your impressions and opinions in comments to this post.
