Severe psoriasis involves thick, raised plaques with heavy scaling, significant inflammation, and often intense itch that standard moisturizers cannot adequately address. The five creams below are chosen specifically for their ability to reduce scale buildup, calm inflammation, and support the compromised skin barrier characteristic of psoriatic skin - using the active ingredients with the strongest evidence base for OTC psoriasis treatment.

CeraVe Psoriasis Moisturizing Cream - Best Overall for Severe Psoriasis
CeraVe Psoriasis Moisturizing Cream is formulated specifically for psoriatic skin with 2 percent salicylic acid to reduce scale buildup alongside ceramides and hyaluronic acid for barrier repair and lasting moisture. The National Psoriasis Foundation has awarded it their Seal of Recognition. The salicylic acid concentration is effective for plaque management without the irritation risk of higher concentrations, making it suitable for daily use on affected body areas. It is fragrance-free, non-comedogenic, and gentler than most coal-tar-based alternatives while still delivering meaningful scale reduction. The best everyday maintenance cream for those with plaque psoriasis across the body.

MG217 Psoriasis Medicated Conditioning Cream - Best Coal Tar Cream for Plaques
MG217 contains 2 percent coal tar, one of the oldest and most clinically validated treatments for psoriasis, in a conditioning cream base. Coal tar slows the accelerated skin cell proliferation that creates psoriatic plaques, reduces inflammation at the affected site, and relieves itch. It is recognized by the FDA as a safe and effective OTC treatment for psoriasis at concentrations up to 5 percent. The conditioning cream base also softens and hydrates while the coal tar acts on the plaque. The characteristic coal tar odor is a trade-off for its effectiveness. Best applied at night and covered to improve penetration and reduce odor during daily activity.

Dermarest Psoriasis Medicated Moisturizer - Best Salicylic Acid Cream for Scaling
Dermarest combines 3 percent salicylic acid, the maximum OTC concentration, with menthol for itch relief in a moisturizing cream base. Salicylic acid acts as a keratolytic, dissolving the protein bonds between the thick, built-up scale cells that form psoriatic plaques, physically reducing the buildup that worsens the appearance and discomfort of severe psoriasis. It is fragrance-free and designed for use on the body rather than the scalp. It is the strongest OTC salicylic acid cream available for plaque scaling, making it particularly effective for thick, well-established plaques on elbows, knees, and legs where lower concentrations provide insufficient exfoliation.

Neutrogena T/Gel Therapeutic Shampoo and Body Treatment - Best for Scalp Psoriasis
Neutrogena T/Gel contains 0.5 percent coal tar extract in a gel format designed for scalp use but also applicable to body plaques. For the estimated 60 percent of psoriasis patients who experience scalp involvement, T/Gel is the most widely available and cost-effective coal tar treatment. It controls itching, flaking, and scaling when used 2 to 3 times per week. The gel format rinses cleanly, which matters for scalp application where residue is visible. For body plaque use, the gel consistency is less practical than a cream, but it remains an effective option for targeted plaque application where the coal tar concentration is sufficient.

AmLactin 12% Lactic Acid Lotion - Best for Thick Psoriatic Scale Softening
AmLactin at 12 percent lactic acid provides strong chemical exfoliation of the thick, hardened scale characteristic of severe plaque psoriasis. Lactic acid dissolves the corneodesmosomes binding dead skin cells in psoriatic plaques, physically reducing thickness and improving the surface texture. It also acts as a humectant, drawing moisture into the outer skin layers as it exfoliates. For very thick plaques, using AmLactin to soften and reduce scale buildup before applying a medicated psoriasis cream improves penetration and effectiveness of the active treatment. It stings briefly on cracked or broken skin, so use it only on intact plaque surfaces.

What to Look For
For psoriasis creams, the four effective OTC active ingredients are salicylic acid (keratolytic/scale reducing), coal tar (cell proliferation slowing), hydrocortisone 1 percent (anti-inflammatory), and urea or lactic acid (thick scale softening). A cream that addresses only barrier hydration will not meaningfully reduce psoriatic plaques. Look for the National Psoriasis Foundation Seal of Recognition where available. Avoid fragrances, which can trigger flares on already inflamed plaques. For psoriasis covering more than 10 percent of the body or affecting the face, hands, or feet, a dermatologist consultation for prescription-strength topicals or biologics should be the primary treatment priority.
Final Thoughts
CeraVe Psoriasis Moisturizing Cream is the best daily maintenance option because it combines effective salicylic acid scale management with ceramide-based barrier repair in a well-tolerated, fragrance-free formula. For thicker plaques, rotate in MG217 coal tar cream at night for its deeper anti-proliferative action. Psoriasis is a chronic autoimmune condition, and no OTC cream resolves it - the goal is consistent symptom control using the right actives applied consistently over time.
Frequently asked questions
What OTC ingredients actually work for severe psoriasis?+
Salicylic acid (1.8 to 3 percent) softens and removes psoriatic scales, improving penetration of other treatments. Coal tar (0.5 to 5 percent) slows the rapid skin cell production driving plaques and reduces inflammation. Hydrocortisone 1 percent provides short-term anti-inflammatory relief. Urea at 10 to 40 percent helps break down thick plaques. These are the four most evidence-supported OTC actives for psoriasis. No OTC cream cures psoriasis - they manage symptoms while the underlying autoimmune activity continues.
Can I use psoriasis cream every day long term?+
Ceramide-based moisturizers and urea creams are safe for daily indefinite use. Coal tar and salicylic acid products can be used daily but may cause irritation with extended use and should be monitored. Hydrocortisone creams should not be used daily for more than 2 to 4 consecutive weeks without a break, as long-term topical steroid use causes skin thinning, rebound flares, and tolerance development. Rotate between steroid and non-steroid treatments and use the lowest effective potency for the shortest necessary time.
Should I moisturize psoriasis plaques?+
Yes. Consistent, heavy moisturization is one of the most important non-medicated components of psoriasis management. Moisturizing reduces the itch, scaling, and cracking associated with plaques, and thick emollients reduce transepidermal water loss that worsens plaque appearance and discomfort. Apply immediately after bathing when skin is still damp. For thick plaques, occlusion with a damp cloth or plastic wrap over a heavy emollient at night can significantly accelerate scale softening and improve the absorption of any medicated treatments applied underneath.
