There are makeups made to hide skin issues like psoriasis. Talk to your doctor about a good product for you. You’ll want to consider thickness. You’ll need a thicker makeup for larger patches that are harder to hide. Look for a color that closely matches the skin tone of the skin surrounding your psoriasis. Gently blend a small amount of the makeup over the area you want to cover. Follow with a dusting of loose powder to make it last longer. You can even use hairspray to help make it set.
