Are Posca Markers Toxic on My Skin? Don’t tell me I’m being poisoned!

Are Posca pens toxic? No they are not toxic. But you should know a bit more and see if there is anything else to worry about as I cover many more Posca pen questions.

Are Posca Markers Toxic?

No, Posca markers are not toxic. Posca markers (also known as paint pens) are acrylic based pens, that means there is no toxic ink inside, no alcohol based ink. 

Just simple water based acrylic paint. 

They are packed with high pigment, they are light fast and have a long lasting ‘ink’.

When they are dry, Posca paint pens are waterproof and resist fading.

They keep their vibrant colors which is why many artists use them as their first choice paint pen when creating art works that pop, on mediums such as glass, wood, plastics and canvas.

Now let’s find out if Posca Pens are toxic in other ways.

Do Posca Pens Smell?

Something stinks? Not Posca

Posca paint pens do not have a smell.

It is barely noticeable and is not on the same scale of strong odor as a typical marker like a Sharpie. 

As I have mentioned, the ink is an acrylic based paint and it smells more like a watered down acrylic paint rather than an alcohol based pen.

Are Posca Markers Safe on Skin?

Posca markers are as safe on skin as an acrylic paint is safe on skin.

This does not take into account an allergies someone may have. 

Yes some people are allergic to acrylic paints or some of the ingredients that are contained in acrylic paints.

If you are unsure, best to do a very small patch test on a part of your skin such as a foot and see if it starts to come up blotchy or red.

If it does, seek medical advice if you are unsure of the severity.

Another thing you need to be aware of that you should not use Posca paint pens as a cosmetic and if you are a tattooist you should not be using Posca pens for outlining your tattoos.

Best to use Copic markers for tattoo outline work.

If you get Posca on the skin, unless you are allergic it is no drama to remove. Simply wash the Posca marker off your skin with plain old soap and water and towel dry.

If you get Posca markers on clothes or other materials, I have a great post which highlights all the ways you can clean Posca paint pens off.

Ingesting Posca Paint or Nib or getting Posca paint in the eyes

Never work with pets and kids they say but sometimes we can’t get around this. If there are children or dogs around then the risk if actually quite higher than usual that one of them will try and either chew a Posca paint pen, get some on their face or in their eyes or try to eat the nib.

If they get Posca paint in their eyes, quickly wash the paint out with running water. 

Follow these guidelines as per the Mayo clinic – whilst Acrylic paint is not dangerous, it is still a chemical and best to be safe than sorry.

If they ingest the nib, this should also pass through without any drama but consult a doctor or vet if you are concerned.

For a child, the choking risk is more of a risk than the actual paint or nib materials causing any poisoning.

I never let my kids use Posca paint pens alone and I am always supervising – not because I am worried about toxicity but I do not want them redecorating the room or themselves!

Do Posca paint pens contain Xylene?

These days even Sharpies and Artline markers are Xylene free.

So we know that the Posca pen is not toxic but this amazing product has other benefits you should know about. The following section covers the many questions you may have or may not know you have regarding Posca pen.

What do you use Posca pens for?

The Posca pen is a versatile tool that can be used on any surface, providing permanent or temporary results. The effects are durable depending if you’re applying it to wood cardstock paper for example; however there may not need to use fixatives like glue because of its ability in working with porous materials such as fabric and plastics too!

What is special about Posca pens?

The versatility of the Posca pen is unmatched. These markers allow you to create rich, opaque water-based paints in any size or shape that can be used for painting and drawing! The pens are made with real paint so they’re durable as well – perfect when paired together on paper surfaces like oil boards or even canvas paintings because all seven sizes will work perfectly no matter what type material it’s being applied too.

Can you mix Posca pens?

As Posca pens are acrylic paint based they can be mixed and blended as you would any acrylic paint. The only issue is that if you are mixing or blending the paint directly with the Posca pen nib, you will start to discolor the Posca pen nib itself. This is where I suggest you use a regular paintbrush and some water to blend the colors together.

Blending should be done before the Posca pen paint dries. The quick drying time of Posca pen paint also allows for superimposition. The high density coverage means that you can create layers with great precision, without having to worry about smudging or running into each other!

Is Posca permanent?

Yes, the paint used in every Posca pen is not just for the moment, it’s designed to last but it can be removed if desired, although this does require some work on your end!
The spray varnish will harden into an invisible finish. You can also make Posca pen permanent on clothing or materials by ironing over the design with a protective sheet of vellum paper on top as you iron. You can also cure Posca pen paint if you are using it on ceramics by popping them into a kiln or low heat oven.

Are Posca pens worth it?

The Posca pen range is great for artists who want to create detailed art with ease. They come in an array of colors and can even draw on paper!

The average rating is 5 out of five stars on Amazon which tends to have very picky buyers, it speaks volumes about how people feel about these pens, but if you’re still unsure then just try pressing down some paint using one – trust me when I say that it will not disappoint at all!!
