Medical Disclaimer: This article is for informational purposes only and is not a substitute for professional dermatological care. Psoriasis is a chronic inflammatory condition requiring proper diagnosis. These products address OTC management of mild-to-moderate body psoriasis. They are not cures. Do not use these products on the face without dermatologist guidance. Consult a dermatologist before starting treatment, especially if you have widespread involvement or have not been formally diagnosed.
Psoriasis is a chronic autoimmune condition in which the immune system triggers abnormally rapid skin cell turnover, producing the characteristic raised, red plaques covered in silvery-white scales. On the body - elbows, knees, torso, lower back, legs - these plaques can be thick, itchy, and slow to respond to treatment.
OTC management of body psoriasis revolves around two active ingredient categories: coal tar (FDA-approved to slow cell turnover) and salicylic acid (to remove the built-up scale). Underneath both is the non-negotiable foundation of intensive moisturization, which prevents cracking, reduces itch, and maintains the skin barrier. The five products below cover all three therapeutic layers.

1. MG217 Medicated Multi-Symptom Coal Tar Cream 2%
MG217’s coal tar cream is the highest-concentration coal tar product widely available OTC. At 2%, it delivers a meaningful dose of the FDA-approved active ingredient that slows the accelerated epidermal turnover driving psoriasis plaques. It directly addresses the cause of scale formation rather than merely removing the scale after it forms.
Coal tar has a characteristic smell and can temporarily stain light fabrics, so MG217 is best applied at night, covered loosely, and rinsed in the morning. Despite its unglamorous profile, it remains one of the most evidence-supported OTC psoriasis treatments available, with decades of clinical use behind it.
Pros:
- 2% coal tar - highest OTC concentration; FDA-approved for psoriasis
- Addresses root cause of plaque formation, not just surface symptoms
- Multi-symptom formula also relieves itch and redness
- Proven clinical track record
Cons:
- Coal tar smell is noticeable - best used at night
- Can temporarily stain fabrics and surfaces
- Not for use on face, groin, or axillae (skin folds)
2. Dermarest Psoriasis Medicated Moisturizer
Dermarest combines 3% salicylic acid with a moisturizing base, making it an effective scale-removal treatment that does not leave skin stripped and dry. Salicylic acid at this concentration softens the protein bonds holding psoriasis scale to the skin, allowing scales to be gently washed away and leaving the underlying skin accessible to other treatments.
It is best applied after bathing when skin is still slightly damp. The moisturizing components help offset the drying tendency of higher-concentration salicylic acid. Use it in rotation with coal tar - salicylic acid in the morning for scale management, coal tar at night for cell-turnover control - for a comprehensive OTC regimen.
Pros:
- 3% salicylic acid effectively removes thick scale
- Moisturizing base reduces typical drying side effect
- Fast visible improvement in flaking and roughness
- Easy to find in drugstores and online
Cons:
- Should not be used on broken skin or large body areas simultaneously (systemic salicylate absorption risk)
- Salicylic acid does not address underlying inflammation - best paired with coal tar
3. CeraVe Psoriasis Moisturizing Cream with 2% Salicylic Acid
CeraVe’s psoriasis formula is the most versatile product in this review: it pairs 2% salicylic acid for scale removal with CeraVe’s signature ceramide and hyaluronic acid complex that repairs the compromised skin barrier characteristic of psoriasis. Where Dermarest prioritizes scale removal, CeraVe prioritizes the balance between exfoliation and barrier restoration.
The inclusion of ceramides (skin lipids that psoriasis skin is deficient in) makes this a more complete daily moisturizer than salicylic acid-only products. It is gentle enough for twice-daily use as a maintenance moisturizer and effective enough as a scale treatment to handle moderate flare-ups without additional products.
Pros:
- Combines 2% salicylic acid with ceramide barrier repair
- Gentle enough for daily use as a maintenance moisturizer
- Fragrance-free; developed with dermatologists
- Addresses both scale removal and underlying barrier deficiency
Cons:
- 2% SA is slightly lower than Dermarest’s 3% for thick plaque
- Cream texture may feel heavy in warm weather
4. Curel Hydra Therapy In-Shower Moisturizer
Psoriasis skin has a fundamentally compromised moisture barrier. Curel’s Hydra Therapy is applied to wet skin in the shower, using water as a carrier to drive hydration into the skin before the moisture-retaining layer is applied. This wet-skin application technique delivers superior hydration compared to applying lotion to dry post-shower skin.
While Curel Hydra Therapy contains no medicated active ingredients, intensive moisturization is foundational to any psoriasis treatment program. Hydrated psoriasis skin has fewer cracks, less bleeding, reduced itch, and responds better to active ingredients. Use it as the daily hydration base that all other treatments build upon.
Pros:
- Wet-skin application delivers superior moisture absorption
- Easy in-shower application - adds no extra step to the routine
- Free of common irritants; formulated for sensitive skin
- Helps maintain results from active ingredient treatments between applications
Cons:
- No active psoriasis ingredients - purely a moisturizer
- Must be used consistently to see cumulative benefit
5. Gold Bond Psoriasis Relief Lotion
Gold Bond Psoriasis Relief combines salicylic acid with colloidal oatmeal - an FDA-recognized skin protectant that forms a soothing barrier over irritated, itchy skin. The dual action targets two of the most bothersome daily symptoms: the scale (salicylic acid) and the itch (colloidal oatmeal’s anti-inflammatory proteins).
Gold Bond’s lotion consistency makes it easier to spread over larger body areas than the heavier cream formats, making it practical for widespread psoriasis across the back, legs, or torso. It is the best choice for patients whose primary complaint is itch alongside the visible scaling.
Pros:
- Dual active ingredients target both scale and itch simultaneously
- Lotion consistency easier to apply over large body areas
- Colloidal oatmeal is gentle and well-tolerated
- Good for widespread psoriasis management
Cons:
- Lotion provides less occlusive moisturization than cream
- Colloidal oatmeal provides symptomatic rather than disease-modifying relief
What to Look For
Coal tar for cell turnover: If you have thick, raised plaques, coal tar is the most important OTC ingredient. Use MG217 at night on affected areas. Avoid on sensitive areas.
Salicylic acid for scale: Before other treatments can penetrate, the scale layer must be addressed. Higher SA concentrations (3%) work faster; lower concentrations (2%) are gentler for daily maintenance.
Moisturization is not optional: Psoriasis skin consistently shows ceramide deficiency. Daily intensive moisturization with products like CeraVe or Curel reduces itch, cracking, and bleeding and improves the effectiveness of active treatments.
>10% body involvement needs a dermatologist: When plaques cover more than 10% of body surface area, OTC treatments alone are unlikely to provide adequate control. Prescription-strength vitamin D analogs, topical corticosteroids, calcineurin inhibitors, and biological therapies offer dramatically stronger outcomes.
Final Thoughts
A practical OTC body psoriasis regimen for most people: apply Curel Hydra Therapy daily in the shower, use CeraVe Psoriasis Cream as the morning moisturizer for daily maintenance, and apply MG217 coal tar cream at night on active plaques. During flares, add Dermarest for faster scale removal. Gold Bond Psoriasis Lotion works well as an additional itch-control tool for widespread areas. This layered approach addresses all three OTC-treatable dimensions - cell turnover, scale removal, and barrier repair - giving your skin the best chance of sustained improvement.
Frequently asked questions
What is coal tar and how does it treat psoriasis?+
Coal tar is an FDA-approved OTC active ingredient derived from coal processing. It slows the abnormally rapid skin cell turnover that causes psoriasis plaques, reducing scaling, redness, and itch. It has been used for over a century and remains one of the most evidence-supported OTC psoriasis treatments. It is appropriate for body psoriasis but should not be used on the face or in skin folds.
When does psoriasis require a dermatologist?+
See a dermatologist if psoriasis covers more than 10% of your body surface area, involves the face, scalp, joints (psoriatic arthritis), or genitals, significantly impacts quality of life, or is not responding to OTC treatment after 8 weeks. Prescription treatments including topical calcineurin inhibitors, vitamin D analogs, and biologics (injectable medications) offer dramatically stronger results for moderate-to-severe cases.
What is the difference between salicylic acid and coal tar for psoriasis?+
Salicylic acid is a keratolytic - it physically softens and lifts the scale layer, making skin smoother and allowing other treatments to penetrate better. Coal tar slows the underlying cell production that creates the scale. They work at different stages and are often used together: salicylic acid first to remove scale, then coal tar or moisturizers to treat the underlying skin.
