The diamond-shaped face is difficult to manage because there are so many points that fight for attention. The chiseled features, the points of the chin, the cheeks and the forehead all need special care. Applying cosmetics can help to bring the facial features forward. You will also need to use makeup to minimize the jaw line and perhaps the temples slightly.
The first cosmetic you’ll apply is a cream concealer, which can make discolorations, redness, brownness and more disappear. Use a cosmetic sponge to apply the cream - when you use your fingers, you bring the oil from your hands up to your face. This transfer of oil could easily cause a breakout of blemishes, so it's best to keep it sanitary.
Working the concealer into the center of the face will create a look of lightness. Bring the makeup in the center of the forehead, under the eyes and on the sides of the nose. Whenever you use any kind of cover up below your eyes, blend it all the way from the socket down to the cheekbones so you cannot tell where the makeup begins or ends. This prevents those “raccoon circles” of lightness that you sometimes see on people. You can also use some concealer over the chin, on top of any skin discolorations and to minimize the appearance of blemishes.
Using two differing colors of water-based foundation, one dark and one light, creates more of a natural appearance than using just one. One foundation almost has a feel of a mask since the color is uniform. In real life, everybody's face is actually made up of many different shades. Using two colors looks more natural, and therefore better.
Using a cosmetic sponge, apply a color that is one shade warmer than your skin tone to the areas that you want to minimize, such as the temples and the jaw line. Keep the center area where you applied the concealer clear. You can also put this makeup on the frontal bones of the eyes if you want to de-emphasize or set back this feature. You don't want this bone to look as if it protrudes too far forward of your face. Blend the foundation into the bone and stroke it upwards into the temple.
Next, choose a lighter shade of foundation, one that is very close to your natural color. Put it on the same areas that you used the concealer - under the eyes, across the nose, forehead and chin. There may be days when you don't want to use cover up - in that case, just apply this foundation. Blend thoroughly. You shouldn't be able to distinguish where the light or dark foundation was applied - the two should blend together on the skin.
Next, use a sponge to apply a translucent powder, preferably one that doesn't have a color. If you apply this makeup with a brush rather than a sponge, the powder tends to lay on the surface and can appear kind of flaky and artificial. So use the sponge to gently press the makeup into the skin. Apply evenly all over the face, blending the powder all the way down to the neck area. Use a makeup brush to buff away any excess powder.
After correcting the face shape with foundations, brush contour powder onto the jaw line to help provide some facial definition. If you feel that your chin, temples or frontal bone protrude, you can cover those areas with some contour powder. This step adds some warmth to your skin tone. If you don't care to wear foundation, you could create the same highlights and shading of the face by using just the powder itself.
To add color to your face, apply some blush with a sable makeup brush. Use your nose as a guideline to determine where your cheekbone starts. Simply draw an imaginary line from the bottom of the nose straight back towards the ears. Starting from the back of the bone, blend the blush forward. Imagine a line extending downward from the outer corner of the eye - do not cross it with your blush. You never want to start your blush in the center of the face and work backwards - this over-accentuates your blush lines, making it too obvious you're wearing blush.
