It is helpful to apply the moisturizing cream while your skin is damp. During the winter months, the humidity is generally lower, especially in homes with forced air heating. This tends to cause dry, itchy skin. Scratching affected skin will worsen your psoriasis and can even cause new lesions to form. Thus, it is important not to scratch, pick, or scrub psoriasis lesions.
Natural sunlight can have a positive effect on psoriasis.
The long-known benefits of sunlight provided the basis for the development of ultraviolet light therapy for treating psoriasis and other skin diseases. However, you should never get enough sun exposure to turn your skin red or cause a sunburn, which can actually cause psoriasis to flare-up and worsen. There is no scientific evidence that homeopathic treatments are effective for treating psoriasis. However, it s not impossible that some of these treatments might be helpful. Scientific studies need to be done in order to resolve this issue.
