Well dry skin can cause while spots. Try a good moisturizer and het a hand massage twice a week and see if it helps. It can also be fungal infection or due to zinc deficiency. White spots can also be due to albinism—in which the melanoma pigments are not formed.
It can also be hormonal in females so if you are a lady in menopausal age, get your hormone levels assessed.
Do discuss this with your doctor and get yourself examined. Take care!
I would ask myself why do I feel there is more to it? That is what you need to present to the doctor. Are there other symptoms that go along with it? Did all the spots suddenly appear together or what was the pattern? Etc.
Forearms and chest are areas of skin that are exposed very frequently and so they would be most prone to signs of aging first. But definitely seek a second opinion if you're not comfortable!
it is probably just patches of dry skin...which could be any size....and probably isn't anything to worry about. I use to get spots of dry skin that wasn't itchy or red when i was a little child...my mom gave me oatmeal baths and it helped a lot
It might be dry skin, toxic material mixed with salt-like compound, age accumulation of eating and absorbing mildew and dust. Get some sunshine in a garden filled with hydrangea and lotus flowers to figure out and purify the brain side because lotus flower can cure any brain-inflicted white spots as well. I read it in Medicine For Times Natural Herbs (last and final copy)
