Is there a "right" way to shower or bathe with psoriasis?
Close enough to one, yes. I read the American Academy of Dermatology page on washing, and it lays out a specific version covering frequency, timing, water temperature, and how to wash. Evidence
- One bath or shower a day.
- About 5 minutes for a shower, 15 minutes or less for a bath.
- Warm water, not hot.
- Hands, not a loofah, buff puff, or washcloth.
Why this matters
- Sources cited, not yet graded
The AAD also recommends a gentle, moisture-rich cleanser made for sensitive skin rather than a deodorant soap or scrub, and rinsing thoroughly. It then recommends drying by blotting rather than rubbing, leaving the skin a little damp rather than fully dry.
Considerations
- Depends on you
This is general self-care guidance, not a measurement of how much it reduces flares for any one person. I checked that AAD page for a byline or a dated review of its own and found neither.
Questions for your dermatologist
Does a cracked or bleeding plaque change this routine?

What actually helps after washing, and how soon?
Moisturize while your skin is still a little damp, within about five minutes of finishing. A thick cream or ointment locks in more moisture than a lotion. A fragrance-free one avoids adding an irritant on top of already-irritated skin. Evidence
Why this matters
- Sources cited, not yet graded
Fragrance is a common irritant, which is why fragrance-free is the specific thing to check for on the label. "Unscented" is not the same thing; it can still contain a masking fragrance.
Considerations
- Depends on you
The AAD page I read does not rank specific moisturizer brands or ingredients beyond thick, fragrance-free cream or ointment. It does not say how long the benefit of a single application lasts.

The itch is unbearable. Is scratching really that bad?
The AAD is direct about this: reach for moisturizer instead of scratching. Scratching tends to worsen psoriasis, and the most effective way to relieve the itch long-term is treating the psoriasis itself, not managing the itch around it. People I have heard from name the itch as the symptom they would most want gone. Evidence
- Moisturize instead of scratching, especially right after washing.
- Try a cool, damp washcloth on the itchy spot.
- Look for an anti-itch product with menthol or camphor.
Why this matters
- Sources cited, not yet graded
Those two ingredients, menthol and camphor, are the ones the AAD specifically calls out as tending to work well for itchy psoriasis.
Considerations
- Depends on you
An anti-itch product is a stopgap while a treatment takes effect, not a replacement for it. The page I read does not quantify how much relief to expect.

A cut, a bug bite, a new tattoo: does an ordinary skin injury actually matter?
For psoriasis specifically, yes, more than it would for most people. The AAD describes a real pattern: an injury like a cut, scrape, sunburn, scratch, bruise, or bug bite can trigger a new patch nearby. So can a new tattoo or piercing, typically about 10 to 14 days later. Evidence
Why this matters
- Sources cited, not yet graded
The AAD names the same 10-to-14-day pattern for a cut from shaving. Its advice is ordinary and practical: treat injuries promptly, avoid scratching, use insect repellent, and talk with a dermatologist before getting a tattoo or piercing.
Considerations
- Depends on you
This describes a known pattern, sometimes called the Koebner phenomenon, not a guarantee. Not every injury triggers a new patch, and nothing I read gives an individual risk estimate for how likely yours is to.
Questions for your dermatologist
Have you seen this happen with my psoriasis before, in a spot I could recognize now?
