Homemade/DIY natural eyebrow gel/filler

I found a recipe from this blog.

The ingredients:

• 1 1/2 tsp almond oil or castor oil
• 2 1/2 tsp cocoa powder 
• 1 tsp cornstarch
• activated charcoal (optional)

I live in Brazil, so any oil wouldn't work, because it would melt in 10min. I tried cocoa powder on its own on my eyebrows but it didn't work. I had to find something else to make it stick to my brows.

I tried Vaseline. First, I applied it with a spoolie on my brows, and then the cocoa powder with a brush. It worked. I tried to melt the vaseline and mix it with the cocoa so it would become a brown gel, and it also worked. Vaseline doesn't easily melts. I wore it today on my eyebrows and it did fade a little, but very little.

I tried using it as a eyeliner, but it didn't work. The Vaseline doesn't have the right consistency. So now I'm searching for a eyeliner recipe.
