Dementors, covered with their long hooded, ripped, black cloaks and soul-sucking mouths are the perfect evil Halloween costume to choose. I love that their look is just a suggestion allowing your mind to get creative and draw its own scary conclusion.

If you are thinking of wearing a Dementor costume this Halloween, then I hope this tutorial will give you some inspiration!

Tools and materials:

  • Face primer
  • Eyelid primer
  • Eyeshadow palette
  • Concealer
  • Gel eyeliner or face paint
  • Highlighter
  • Lip-liner (flesh-colored)
  • Creamy eyeshadow stick
  • Makeup brushes
Applying primer

1. Prime

Start by priming your face and lids to create the ideal canvas for your makeup look.

Outlining shape of Dementor's face

2. Outline the shape of the Dementor’s face

Using a brownish eyeshadow and brush, roughly outline the shape of the face to capture their gaunt appearance, making sure to call attention to the high cheekbones.

Defining mouth

3. Define the shape of the mouth

Block out your lips with concealer and then with the same brownish eyeshadow start working on the shape of the mouth, which is pretty much a black circle.

Adding texture

4. Add texture to the cheeks

Add some texture to the hollows of the cheeks. We will come back to this but in the meantime just get the lines started. We are trying to capture that gray, wrinkled, nasty skin to really amp up the creepy factor for your Dementor costume.

Filling in lips

5. Fill in the mouth

Gel eyeliner is perfect for creating the gaping mouth used to perform the harrowing Dementors kiss; it’s long-lasting and super opaque.

Use the eyeliner to first draw a circle around your mouth and then fill the whole lip area. If you do not have gel eyeliner, face paint is also a good option.


Muddying skin

6. Muddy-up your skin

Using a muddy color eyeshadow, start covering your skin, to resemble their decaying gray appearance.  

Applying black eyeshadow to top half of face

7. Block out the top half of your face

A hood will cover the top half of your face, so we want to try to make this area appear non-existent.

A great way to do this is using black eyeshadow and dusting it over the whole area we want to cover up making sure to blend it well.

Sculpting cheekbones

8. Sculpt the cheekbones

Return to your cheekbones, going over them with a darker color than before, and blend the shadow down to really try and get that skeletal look.

Adding highlight

9. Highlight higher points

At this point, you can go back with more shading, and then it’s time to highlight areas like the top of the cheekbones and around the mouth, with a light-colored eyeshadow.


Enhancing the mouth

10. Enhance the mouth

Use a flesh colored lip liner, to create a bit more highlight around the mouth to get a puckered look.

Go back in with more of your light-colored eyeshadow to really highlight the mouth so you perfectly capture that terrifying kiss.

Adding intensity

11. Intensify the colors

Go back and intensify the colors around your face, making the darks a little darker and the lights a little lighter, keeping it nice and textured.

Adding contrast to Dementor look

12. Add contrast

The last step on the face is to create more contrast with a creamy eyeshadow stick to make the whole look a little bit more pronounced.

It is a Harry Potter Dementor costume after all, so it doesn't need to be too subtle. Blend it out a little bit but really focus on high contrast color.

Also, work some textured lines down the neck being sure to cover any part of your skin that is visible, and then do the same thing with a white eye shadow pencil creating more highlights wherever you see fit.

Skeletal hands for Dementor costume

13. Create the skeletal hands

Make the hands look creepy and skeletal using the same black gel eyeliner as used on your mouth. Color in the sides of your finger to make them look slimmer and longer.

Then, when the rough shape is done, go over it again with gray and black eyeshadow. Finish this off with a few highlights on the highest point of your hands using that same creamy eyeshadow stick again.


Completed Dementor costume

And here is your Dementor makeup all done. This was so much fun. If anyone is thinking of wearing a Dementor costume this Halloween, I would love to hear how you plan on styling it and I really hope this tutorial helps with some ideas.

    Great job. Do you recommend some type of makeup setting spray on the hands so that the black gel eyeliner does not rub off? Or did you use the kind that stays put? Thank you for sharing your process.
