Psoriasis is a chronic autoimmune condition that affects millions of people worldwide. It causes the skin to become inflamed, red, and scaly, leading to discomfort, pain, and embarrassment. While there are many triggers that can cause psoriasis to flare up, one of the most common triggers is the use of certain soaps. Sulfates and fragrances are the main culprits in soaps that can trigger psoriasis flare ups. Sulfates, such as sodium lauryl sulfate and sodium laureth sulfate, are commonly used in soaps as surfactants to help create lather and remove dirt and oil from the skin. However, sulfates can also strip the skin of its natural oils, leaving it dry, itchy, and irritated, which can trigger a psoriasis flare-up. Fragrances, which are added to many soaps to give them a pleasant scent, can also cause skin irritation and trigger psoriasis.

In this listicle, we’ll explore the different treatments—like Skyrizi, Tremfya and Otezla—that can help calm psoriasis when aggravated like personal care products, like soaps:

1. Topical creams and ointments

Topical creams and ointments are often the first line of defense when it comes to treating psoriasis. These medications are applied directly to the affected area and work to reduce inflammation and relieve itching. Common topical medications include corticosteroids, calcipotriene, and tazarotene.

2. Oral or injected medications

For more severe cases of psoriasis, oral or injected medications may be necessary. These medications work to reduce inflammation throughout the body and are typically reserved for people with moderate to severe psoriasis. Examples of these medications include Tremfya and Otezla.

3. Light therapy

Light therapy, also known as phototherapy, involves exposing the skin to ultraviolet light under medical supervision. This treatment is often used for people with moderate to severe psoriasis and can be done in a doctor’s office or at home using a special light box. Light therapy can help reduce inflammation, relieve itching, and improve the appearance of psoriasis.

4. Coal tar

Coal tar is a topical treatment that has been used for psoriasis for over 100 years. It works by slowing down the production of skin cells and reducing inflammation. Coal tar can be applied as a shampoo, cream, or ointment and is often used in combination with other psoriasis treatments.

While using certain soaps can trigger psoriasis flare ups, there are many different treatments available to help calm psoriasis. Topical creams and ointments, oral or injected medications, light therapy, and coal tar are all effective treatments that can help reduce inflammation, relieve itching, and improve the appearance of psoriasis. If you’re struggling with psoriasis, speak to your doctor about which treatment options may be right for you, such as Skyrizi, a medication that was approved by the FDA in 2019 for treating moderate to severe psoriasis.
