Yes, shimmer powder and highlighter are two different makeup products. Both products are used to shine different areas of your face.

Shimmer Powder 

Shimmer is available in certain highlighters, lipstick and eyeshadows to bring some shine. It is used in the eyeshadow for glowy and bigger eyes. Finely milled glitter or pearl is added to the makeup products, named as shimmer.

Highlighter 

It’s a makeup product used to give dimension and enhance the appearance of the skin. It is used on the high points of the skin, such as cheekbones, nose, chin and cupid’s bow to give a radiant effect. Highlighter is used in different products like creams, powder, and liquid, which are available in different shades as per skin tones.

Shimmer gives dimension and illumination, on the other hand, highlighter is used to enhance the high points. Shimmers are used all over the body to create a more dramatic look, whereas highlighters are used on specific areas. Before using any of the products, read their ingredients carefully. For highlighters, identify your skin tone. If you don’t have clear ideas about these, contact a professional esthetician for better suggestions.
