Salicylic Acid for Psoriasis

Although psoriasis has no cure, a variety of treatments are available, including topical creams, medication, and light therapy. One common topical treatment is salicylic acid. Read on to learn how salicylic acid works to treat psoriasis.

How does it work for psoriasis?

Salicylic acid helps soften, lift, and clear away flakes of skin on psoriasis plaques. It may also reduce swelling.

It is often used in combination with other topical treatments, as removing scales may help to improve the effectiveness of some treatments.

What salicylic acid concentration is okay for psoriasis?

The recommended concentration of salicylic acid for psoriasis ranges from 2 to 10 percent. Products with higher concentrations may only be available with a prescription.

In addition, keep in mind that while higher concentrations may be more effective at removing scales, they are also more likely to cause side effects. They may even worsen your psoriasis. Your doctor can help you find the right concentration.

There are many OTC products that contain salicylic acid for psoriasis. The following products were chosen based on their ingredients, customer reviews, and brand reputation. Ask your dermatologist for additional recommendations.

SkinMedica’s facial cleanser includes both alpha- and beta-hydroxy acids to boost exfoliating action. Reviewers say it keeps their skin feeling smooth and clear.

How can you use salicylic acid for skin care?

Follow the instructions on the product or prescription label carefully.

When you first start using a salicylic gel, cream, lotion, or ointment, apply only a small amount to a single patch of psoriasis. Try this for several days to see how your body reacts.

At first, you might find that symptoms such as dryness and itchiness worsen as your skin adjusts to the treatment. If you don’t experience any significant side effects, you can begin using the product as directed.

Apply salicylic acid to patches of psoriasis as needed up to several times per day unless otherwise directed by your doctor or pharmacist. Note that it may take a few weeks before you see an improvement.

You should avoid applying salicylic acid to more than 20 percent of your body surface area, as it is absorbed through the skin and too much can cause side effects. In addition, steer clear of your eyes, nose, mouth, and genitals.

If you specific concerns about using salicylic acid and your skin, routines, or health, it’s best to speak to a dctor or pharmacist.

What’s the effectiveness of salicylic acid for psoriasis?

According to a 2017 literature review, no randomized controlled studies have evaluated the use of salicylic acid alone in the treatment of psoriasis.

Most studies have instead investigated its use alongside other treatments, particularly topical corticosteroids, anthralin, and immunomodulators.

What are salicylic acid side effects?

The most common side effects of salicylic acid are irritation, dryness, and stinging at the site of application. Although these symptoms aren’t usually cause for concern, you should talk to your doctor about them if they persist.

Other side effects of salicylic acid are rare, but potentially serious. You should seek emergency medical assistance right away if you experience any of the following:

  • confusion
  • diarrhea
  • hair loss
  • headaches
  • hearing problems
  • light-headedness
  • nausea and vomiting
  • rapid breathing
  • tinnitus
  • weakness and fatigue

Other topical treatments for psoriasis

There are several other topical treatments for psoriasis, some of which may be used in combination with salicylic acid. They include:

  • Anthralin. This tar product has anti-inflammatory properties and reduces scales. It must be washed off after it is applied. Using salicylic acid in combination with anthralin is more effective than using anthralin alone.
  • Calcineurin inhibitors. Also known as immunomodulators, calcineurin inhibitors reduce inflammation and plaque growth. They can be used alongside salicylic acid.
  • Coal tar. Topical coal tar may work to relieve psoriasis by suppressing the synthesis of DNA. It can be used alongside salicylic acid.
  • Corticosteroids. Mild-to-moderate strength topical corticosteroids help to reduce and prevent symptoms of psoriasis. They are commonly used alongside salicylic acid, which improves their effectiveness.
  • Moisturizers and emollients. Thick moisturizing creams and ointments help to lock in moisture, ensuring that the outer layer of the skin stays hydrated. They can be used alongside salicylic acid.
  • Retinoids. Retinoids are synthetic versions of vitamin A found in a variety of skin care products. They may help with psoriasis by slowing skin cell growth and reducing inflammation.
  • Vitamin D analogs. These synthetic versions of vitamin D reduce skin cell proliferation. Calcipotriol, a vitamin D analog, should not be used in combination with salicylic acid.
