Psoriasis is a rash that is often scaly and red. Pityriasis rosea is the most common form of psoriasis. It looks similar to ringworm, appearing as an annular patch that is commonly referred to as a herald patch. Similar rashes will later appear on the extremities and the trunk, but Pityriasis rosea won’t usually spread to sun-exposed areas. This condition can last up to 6-12 weeks, but may spontaneously resolve.* The time frame and absence of future recurrence suggest that this condition is virally mediated. Moisturizers, non-soap cleansers, and even topical steroids can help.* In terms of therapeutic agents, outdoor sunlight therapy is very helpful if you avoid sunburns.* It will frequently and quickly induce a remission.*
