There are several pigmentation disorders that look very much like each other yet require different methods to resolve them.
The most common type of pigmentation are associated with sun damage. These are called solar lentigines. These are usually darker and with very clear borders. Some of these can be treated with creams or serums alone.
I prefer to use a combination of the picolaser and creams or serums to treat pigmentation. Depending on the method or protocol used, you may have the pigmentation initially getting darker before flaking off in 1 to 2 weeks.
Other types of pigmentation tend to fade gradually over time. I often describe these pigmentation like cups of tea. Our goal is to empty out the cups without breaking them. If we break the cups, what is left will be a permanent white spot. Because we to not aim to destroy the cells that produce pigment, it also means that the pigmentation can come back.
Prevention is key. Use sunblock regularly. Perhaps consider going for maintenance treatment every so often.
