Do NOT start by using water. The water will only wash out the top layers of the paint, but won’t break up the pigment and may pack the pores of the skin more with paint. So, start by using soap.
Use liquid or bar soap with a few drops of water (baby soap is generally safe around the eye area).
Massage painted area with fingertips until a muddy consistency is formed.
Use a wet wipe, makeup remover wipes or moisten a paper towel to wipe away the paint.
Rinse face with warm water. Repeat steps #2 — #5, if necessary.
Do NOT use scrubs or alcohol! Just gently rub the skin and remember, that sometimes it may take a couple times to remove the paint completely.
To remove tough areas, use any gentle oil without a strong fragrance. I personally prefer coconut or olive oil.
Staining can usually occur due to two reasons and oil work great for both of the situations:
The paint got onto the eyelid area, which has a high concentration of glands that secrete oils. These secretions will adhere the pigments and they can be difficult to wash away with simple soap and water. So just apply a little bit of oil on the eyelids and massage them gently, you will see how the pigment will break down. Then just wipe it off with a wipe or a cotton disk.
The paint has a strong pigment. That usually happens with waxy paints like blue, teal, green and sometimes purple. Glycerin based paints usually don’t stain. The paint can also stain more on dry skin, because of being absorbed by dry top layers of the skin. Again, removing with oil will help greatly.
