Where I live the nearest dermatologist is hours away. Tanning beds help but I would like to have something more convenient at home.
Try vasaline..... not too thick of a layer but it helps it to stay moist so it doesnt crack and hurt. Also i found banana peels help you just rub the moist side of the peel on your psoriasis and leave it or aloe, you can use the gel bought in the store like for sunburns but fresh from a plant is even better just open a small piece of it and rub it on. These are just some natural home remedies i found very helpful while i wasnt on any medication
