What i mean by spreading is, when I first noticed it, there were only small light spots on my cheeks. But over time, the spots have become darker and have also appeared on new areas that were once clear. I am not sure if it is actually spreading or if the new spots are just surfacing.SusanRL, I would like for you to explain to me more about Melasma. I knew that birth control could be a factor and the whole pregnancy thing, but what I don't understand is thatthat melasma can spread? When I think of spreading I think of rash spreading, but with melasma is it really spreading or is it just appearing in other areas do to the circumstances or medicine. Poison Ivy spreads when I think of melasma appearing I think of freckles appearing. Please explain I want to understand your opinion better.
