Psoriasis is a chronic autoimmune skin condition that causes inflammation in the skin, resulting in red, scaly, and often itchy or painful patches on different parts of the body. Symptoms flare up when an overactive immune system speeds up the life cycle of skin cells, leading to buildup on the surface. Common treatments include topical steroids, oral medications, light therapy, and biologic drugs that target specific parts of the immune system. While these treatments can be highly effective, many people with psoriasis are also interested in complementary treatments to help manage symptoms or improve their skin health. Collagen, a key protein in skin, muscles, tendons, and more, is one supplement that often comes up in conversations. But does collagen actually have any benefits for psoriasis that are backed by science?
What Is Collagen?
Collagen is a protein found throughout the body, helping with the formation of skin, muscles, tendons, ligaments, and connective tissues. but collagen levels in our bodies naturally decline as we get older, which is why collagen supplements are frequently enough marketed to improve skin firmness and elasticity. “Collagen is the protein that fills the deeper layers of skin, and decreases in collagen with age cause us to look older, with more wrinkles. The concept of collagen supplementation is that you want your body to make more collagen in your skin, so you eat collagen, as it has all the ingredients necessary to make more collagen,” says Steven Daveluy, MD , a professor and the program director at Wayne State University’s School of Medicine in Detroit, where he specializes in treating patients with skin diseases, such as psoriasis and eczema.Collagen can be consumed or used in several ways.
Orally as a supplement: Collagen supplements are sold in the form of powders, pills, or liquids. Most are made up of collagen peptides or hydrolyzed collagen, which are broken-down forms of the protein that are easier to absorb. They’re sometimes paired with additional nutrients related to skin and hair health,like biotin ,vitamin C,or zinc.
Topically: Collagen is also included in many creams and serums, but it’s effectiveness in boosting collagen production is questionable, says Steven Feldman, MD, PhD , a professor of dermatology at Wake Forest University in Winston-Salem, North carolina. That’s because topical collagen is too large to seep thru the skin and into the body, so it only works on the outside like a moisturizer. “if you’re putting it on the skin, it wouldn’t be absorbed. It would just sit on the surface,” Dr. Feldman says.
through food: Foods high in collagen, such as bone broth , won’t directly raise your collagen level, because your body can’t absorb whole collagen; it has to break it down into amino acids first. But it is thoght that eating foods rich in the amino acids that make collagen – glycine, proline, and hydroxyproline – as well as foods containing vitamin C, zinc, and copper, which are necessary for collagen production, can boost collagen production in the body. This is the preferred route for building collagen and supporting the collagen production process from within, Dr. Daveluy says. “A healthy diet already has those same amino acids and vitamins [as a collagen pill]. I’m a big fan of getting

recent interest in collagen supplementation for skin health has extended to individuals with psoriasis, but current medical consensus indicates limited evidence supporting its effectiveness for managing the condition. Dermatologists advise caution and consultation with a physician before initiating collagen treatment, due to potential adverse effects and lack of conclusive research.
psoriasis: Understanding the Autoimmune Condition
Table of Contents
Psoriasis is a chronic autoimmune disease that accelerates the skin cell lifecycle, resulting in the rapid buildup of skin cells, leading to scaly, itchy patches.
The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) defines psoriasis as a condition affecting approximately 3% of the U.S. population. living with psoriasis frequently enough requires ongoing management to control symptoms and improve quality of life.
Common psoriasis treatments include topical corticosteroids, phototherapy (light therapy), systemic medications, and biologic therapies. These treatments aim to slow skin cell growth and reduce inflammation.
Current Psoriasis Treatments
Standard psoriasis treatments target either the immune system or skin cell growth. Topical steroids remain a mainstay for mild to moderate psoriasis, reducing inflammation and scaling.
According to the American Academy of Dermatology (AAD), light therapy, specifically narrowband UVB, is effective for widespread psoriasis. narrowband UVB phototherapy works by slowing skin cell growth and reducing inflammation.
For more severe cases, systemic medications like methotrexate or cyclosporine, and biologic drugs targeting specific immune pathways (like TNF-alpha or IL-17), are often prescribed. As of December 2023, the AAD reported significant advancements in biologic therapies, offering more targeted and effective treatment options.
Collagen Supplementation and Psoriasis: The Evidence
current research does not demonstrate a clear or direct benefit of collagen supplementation for improving psoriasis itself. While collagen is promoted for skin health, its impact on the underlying autoimmune processes driving psoriasis is not well-established.
A review published in the journal *Nutrients* in December 2023 (Collagen Sources and the Skin) highlights collagen’s role in skin structure and hydration, but notes a lack of robust clinical trials specifically evaluating its efficacy in psoriasis management. The review emphasizes the need for further research.
The primary focus of collagen research has been on improving skin elasticity and reducing wrinkles in aging skin, rather than addressing the inflammatory and immune-mediated aspects of psoriasis.
Dietary Supplement Regulation and Safety
Collagen supplements are regulated as dietary supplements by the U.S. Food and Drug Governance (FDA), and are not subject to the same rigorous testing and approval process as prescription medications.
The FDA does not approve dietary supplements before they are sold. Manufacturers are responsible for ensuring their products are safe and accurately labeled. This means the quality and purity of collagen supplements can vary significantly.
The FDA warns consumers to be cautious about health claims made about dietary supplements and to consult with a healthcare professional before use, especially if they have existing medical conditions or are taking other medications. Potential adverse effects can include allergic reactions and interactions with existing treatments.
Consulting a Dermatologist
Dermatologists recommend discussing any potential new treatments, including collagen supplements, with a healthcare professional before starting them.
