Exposing the affected areas to sunlight can help ease the psoriasis
flare up, but natural sunlight is better for your skin since tanning
beds can be too harsh. Remember that the Sunlight has uncontrolled UVA rays which are a risk factor for Skin Cancer
. The PUVA
is better than sunlight treatments for Psoriasis. Try natural remedies as well, like pasteurized creams, bee's wax, and lemon oil. They are really effective and cost less as well.
