I have this behind my left ear, is this a Seborrheic Keratosis? I have tried all types of creams including topical steroids, it wouldn't go away but it just became smaller though but there's a crust on it. Appreciate some help here. Just curious to know what it is and how to treat it.

It's not painful, itchy or anything, just that it looks ugly behind my ear. Hope someone can shed some light. Thanks!

Yes, it is most likely Seborrheic keratoses. Seborrheic keratoses are (benign) skin growths, and it's a hereditary skin condition. Alpha hydroxy lotions and mild topical steroid creams may help treat this condition. But I think you should see a dermetologist. He/she can tell you which treatments are best for your seborrheic keratosis and remove it in one procedure.

I'm using topical steroids, it managed to flatten and reduce its size. I did see a few doctors, they told me that it's nothing to be worried about so that's it's a little unsightly. Actually, the size is not the big, I took the picture of it in macro mode with my digital camera.
