Skincare Routine for Psoriasis: What Helps & What Hurts

Why Skincare Matters in Psoriasis

The skin barrier in psoriasis is not just disrupted where plaques are visible. Research using transepidermal water loss (TEWL) measurements shows that barrier dysfunction is systemic in psoriasis patients — non-lesional skin (skin that looks normal) also has elevated TEWL compared to healthy controls. This means the entire skin surface is more permeable, loses water faster, and is more susceptible to irritation than in people without psoriasis.

This has a direct implication for skincare: moisturizing is not simply a comfort measure. Restoring barrier function reduces the inflammatory cytokine load, lessens itch and tightness, softens plaques so prescribed topicals penetrate better, and extends periods of remission. A 2021 study in PMC found that occlusive emollients (particularly petrolatum-based) significantly reduced TEWL in psoriatic plaques, while water-based formulas could worsen TEWL — an important distinction when choosing products.

A 2023 clinical review in Dermatology and Therapy confirmed that gentle cleansers and moisturizers play an adjuvant role in both active psoriasis treatment and maintenance during asymptomatic periods, though the evidence base for specific products remains an active area of research.

What to Look for in Psoriasis-Safe Products

Cleansers

Dermatologist-recommended brands widely cited for psoriasis-compatible cleansing include Vanicream, CeraVe, and Cetaphil. These are fragrance-free, dye-free, and formulated to minimize irritant contact.

Moisturizers and Emollients

The most effective emollients for psoriasis are:

• Occlusive agents: White petrolatum (petroleum jelly), mineral oil, dimethicone — sit on the skin surface and physically prevent water evaporation. The 2021 PMC study showed petrolatum most effectively reduced TEWL in psoriatic plaques.
• Ceramide-containing formulations: Ceramides are the dominant lipids in the skin barrier and are reduced in psoriatic skin. A randomized controlled trial found that a ceramide-containing moisturizer produced significant improvement in psoriasis appearance and provided symptom relief.
• Humectants (glycerin, hyaluronic acid): Draw water into the epidermis; most effective when used under an occlusive to prevent the drawn water from evaporating in dry environments.
• Emollient-rich creams and ointments: Ointments (e.g., aqueous cream, E45 emollient ointment) have higher lipid content than creams and are more effective for very dry, thickened plaques. Creams are more cosmetically acceptable for daytime use on body and face.

Ingredients That Often Cause Problems

The following ingredients are documented irritants for people with a compromised skin barrier and are best avoided in psoriasis-prone skin:

• Fragrance and parfum (including "natural" essential oils, citrus extracts): The most common contact allergen and a documented irritant for impaired skin barriers.
• Sodium lauryl sulfate (SLS): An aggressive surfactant that disrupts the lipid bilayer of the skin; found in many standard soaps, shampoos, and toothpastes.
• High-strength alcohols (SD alcohol, denatured alcohol, ethanol): Drying and disruptive to barrier lipids. Fatty alcohols (cetyl alcohol, stearyl alcohol) are fine — these are emollients, not irritants.
• Physical exfoliants (scrubs, loofahs, brushes) on plaques: Mechanical trauma triggers the Koebner phenomenon — new psoriasis plaques appearing at sites of injury. Reserve physical exfoliation only for unaffected areas if at all.
• Harsh chemical exfoliants (glycolic acid, lactic acid at high concentrations) on active plaques: Disruptive to an already-compromised barrier. Salicylic acid at low concentrations (2–5%) is an exception — it is used therapeutically in psoriasis but should be directed at plaques only, not surrounding skin, and not during pustular or erythrodermic phases.
• Dyes and preservatives: Parabens (in some sensitive individuals) and formaldehyde-releasing preservatives (DMDM hydantoin, diazolidinyl urea) can trigger contact dermatitis in sensitized individuals with compromised barrier function.

The Psoriasis Skincare Routine: Step by Step

Morning Routine

Step 1 — Gentle cleanse (or rinse only) If you showered at night, a simple rinse with lukewarm water in the morning is often sufficient. If you cleanse, use a fragrance-free, SLS-free cleanser. Pat (do not rub) the skin gently dry with a soft towel.

Step 2 — Apply prescribed topical treatment if morning dosing If your dermatologist has prescribed a morning topical (such as a vitamin D analogue like calcipotriol, or a combination product), apply it to plaques only before moisturizing. Let it absorb for a few minutes.

Step 3 — Apply moisturizer while skin is still slightly damp Within 3 minutes of patting dry (the "soak and seal" approach), apply a generous layer of a fragrance-free, ceramide-rich cream or ointment over all areas of the skin — not just visibly affected patches. The slightly damp skin surface helps lock in water.

Step 4 — Apply SPF 30+ to face and exposed skin Sun exposure in moderate doses is beneficial for many people with psoriasis, but sunburn is a documented trigger for Koebner-effect flares. A mineral (zinc oxide, titanium dioxide) sunscreen is a good option as it is less likely to cause irritation than chemical UV filters in sensitive skin.

Evening Routine

Step 1 — Bathe or shower in lukewarm water (not hot) A short (10–15 minute) bath or shower is preferable. Prolonged hot water soaking worsens barrier disruption and strips skin lipids. Oatmeal baths (colloidal oatmeal) have a long history of use for itch relief and have anti-inflammatory properties supported by clinical evidence.

Step 2 — Gentle cleanse Use a fragrance-free body wash or bar cleanser. Avoid scrubbing plaques with a cloth or sponge — apply cleanser gently with your hands.

Step 3 — Pat dry and apply keratolytic if needed If plaques have significant scale buildup, apply a salicylic acid product (2–5%) to the plaques to help soften and lift scale. This improves the penetration of prescription topicals applied afterward. Leave for 10–15 minutes or as directed.

Step 4 — Apply prescribed topical treatment to plaques Apply your dermatologist-prescribed topical (corticosteroid, vitamin D analogue, tazarotene, or calcineurin inhibitor) to plaques as directed. Potent corticosteroids are typically applied once daily to affected areas only.

Step 5 — Seal with emollient Over the prescription treatment and all skin, apply a generous layer of your emollient moisturizer. For very dry or thickened plaques, an ointment formulation at night provides superior occlusion. For body areas, thin cotton clothing or pajamas over emollient can enhance overnight absorption without smearing.

Specific Skin Areas

Face

Facial psoriasis is particularly challenging because the skin is thinner and more sensitive. Potent corticosteroids are avoided on the face long-term due to the risk of telangiectasia and atrophy. Dermatologists typically prescribe low-potency corticosteroids, tacrolimus (a calcineurin inhibitor), or pimecrolimus for facial plaques. A fragrance-free, non-comedogenic facial moisturizer applied twice daily is important.

Scalp

Scalp psoriasis is discussed in depth on the /scalp-psoriasis-guide page. In brief: medicated shampoos containing coal tar (1–5%), zinc pyrithione, or ketoconazole can help reduce scale; prescription topical corticosteroid solutions, foams, or shampoos (such as clobetasol propionate 0.05% shampoo) are effective for scalp plaques. After medicated washing, a light leave-in conditioner on the lengths keeps hair manageable.

Body Plaques

Body plaques often tolerate and benefit from thicker ointment-based emollients. Occlusive dressings over topical corticosteroids on thick body plaques can significantly increase penetration and efficacy — only use occlusion under dermatologist instruction, as it also increases systemic absorption and side effect risk of potent steroids.

Hands and Feet (Palmoplantar Psoriasis)

The thick skin of palms and soles requires high-potency corticosteroids and may benefit from occlusive dressings. Soaking hands in lukewarm water before applying treatment helps soften the scale. Protecting hands with cotton-lined gloves when using harsh household products is important — chemical irritants worsen palmoplantar psoriasis.

Bath Additives and Complementary Products

Colloidal oatmeal: Clinically proven anti-itch and anti-inflammatory properties; added to bathwater or present in moisturizer formulations. Particularly helpful during flares with significant pruritus.

Bath oils: Can supplement skin lipids and reduce TEWL during bathing; useful for dry, widespread psoriasis. Apply to the water or onto damp skin immediately after bathing.

Coal tar preparations: Coal tar (0.5–5% in creams or shampoos) has anti-proliferative and anti-inflammatory properties and is an OTC option for mild psoriasis. It has a distinctive odor and can stain clothing and bedding. It is not appropriate during pregnancy.

What to skip: Apple cider vinegar applied directly to plaques, bleach baths (not evidence-based for psoriasis the way they are in eczema), and essential-oil-heavy "natural" products — fragrance is a trigger regardless of its natural source.

Lifestyle Factors That Support Skincare

• Humidifier in winter: Central heating dramatically reduces indoor humidity, increasing TEWL. A room humidifier helps maintain skin hydration, particularly overnight.
• Loose, breathable clothing: Tight, synthetic clothing creates friction and heat against plaques — a potential Koebner trigger. Loose, natural-fiber (cotton) clothing is preferable.
• Stress reduction: Psychological stress is one of the most commonly reported psoriasis triggers and has documented immunological mechanisms (cortisol, neuropeptides). Stress management — whether mindfulness, exercise, or talking therapy — is a meaningful adjunct to skincare.
• Diet and alcohol: Avoiding heavy alcohol consumption, which is a documented psoriasis trigger, and maintaining a healthy weight (obesity worsens psoriasis severity) support overall management.
