Hi
The most important part of treatment pigmentation is first a correct diagnosis by an experienced doctor.
Freckles are mainly due to genetic predisposition and though it is easily removed, will certainly return when your skin is exposed to the sun so sunblock and sun avoidance is so important.
Lentigens or sunspots occur in sun exposed area of face and body and is due to photodamaged of underlying skin. Under special photograph filters, once can easily notice a vascular abnormality under the pigments. To successfully treat lentigines, I will suggest using the Excel V laser which reverses some of the photodamage. If the lentigene is very faint, sometimes a touch up with Picosure laser can blast the small pigments into really fine particles for the body to clear easily.
Some pigmentations such as Adult bilateral naevus of ota macules (ABNOM) are deep in skin and will need multiple sessions with a highly powered laser for best results.
Melasma is often under-diagnosed. If there is underlying melasma of the skin, fractional lasers can sometimes make the melasma worse.
There are many types of pigmentations and many different ways to achieve a good outcome. Please consider going to a doctor experienced with pigment treatments for a better outcome.
