I've had scalp psoriasis for a few years now and I'm happy to say I have it mostly under control. I use a prescription shampoo from the dermatologist a few times a month and an over-the-counter (OTC) one for seborrheic dermatitis the rest of the time. My favorite is Philip B. Anti-Flake Relief Shampoo ($60). This keeps any flakes or red rashes at bay.

But recently, I was worried when I saw those same scaly patches popping up on my body, mostly around my neck, down my shoulders, and in my armpits (the latter is called inverse psoriasis). If you've ever touched a psoriasis patch, you know the dry and scaly feeling that's unlike typical dry skin. It also itches -- a lot.

I headed to the dermatologist thinking another prescription was in my future, but I was happy to learn my case is still on the mild side and can probably be handled with OTC treatments. Still, I wanted to nip it in the bud before it got worse. The CeraVe Psoriasis Moisturizing Cream ($24) is the product that helped the most -- here's my review.

My skin is pretty itchy regularly, so my bathroom is full of heavy moisturizers. Moving to a dry climate like Los Angeles made my skin even drier and itchier than it was when I lived in humid NYC. But for my psoriasis patches, even my most hydrating cream wasn't cutting it.

Psoriasis creams are unlike typical dry skin moisturizers in that they include some type of chemical exfoliant to gently remove the dead skin cells that live on top of psoriasis patches.

Here's the regimen that ended up working for me: I applied my regular lotion to my body and added CeraVe Psoriasis Moisturizing Cream to the scaly areas. I could have used the CeraVe cream on my whole body, but I was nervous the salicylic acid would irritate my sensitive skin. Fortunately, it didn't. In fact, when I woke up, I noticed how much softer the red rash areas were literally overnight. They weren't gone, but they were lighter in color and a lot less itchy.

After using CeraVe Psoriasis Moisturizing Cream for a few weeks, I pretty much forgot about my psoriasis altogether. It's not the only product I use -- this Noble Formula 2% Pyrithione Zinc (ZnP) Bar Soap ($13) saves my underarms -- but I'm so impressed with CeraVe's quality for the price, it's front-and-center in my rotation.
