Customer Question

Hello there,
the skin on my legs is full of white patches, they are not very visible but become a lot more apparent when I am sun tanned, the white areas don't seem to get tanned at all, would you know what it could be?

Is this something you have had for a long period of time?
Is there any scaling?
How large are the patches? Are they tiny?
Are you fair skinned?

Hello there,

I've had this for about three years, it started on holiday.

There is no scaling and is not itchy at all, some of the patches are tiny, white and round and others are areas where the skin does not sun tan at all, even these areas are quite small but all over.

My skin is white but not that fair, I do get sun tanned when I go on holiday and this condition is embarrassing as the more I get sun tanned the more is apparent.

Thank you for the additional information,

I suspect that you have one of two things going on.

First would be a fungal skin infection called tinea versicolor. This can cause white patches of skin that do not tan. It is treated with antifungal medications or shampoos. You can try lotrimin AF over the counter cream for two weeks and see if this makes a difference for you (although typically prescription strength medications are used). Here is more information for you to read about tinea versicolor:

The second, and in my opinion possibly the more likely, cause is idiopathic guttate hypomelanosis. The cause of this is really not known. It is basically areas of skin that lacks the ability to produce melanin (pigment) and becomes more common as we get older. There are some things that can be tried as treatment (steroids, laser, retin-A type creams) but these would have to be done through a dermatologist.
