Hi,
Based on your photo, it appears that you have either melasma or solar lentigenes (or both). This requires face-to-face examination for a more accurate diagnosis.
The type and number of treatment sessions will depend on your type of pigmentation.
For most forms of pigmentation, I use a combination of Picolaser (picoplus) and whitening creams (Hydroquinone) or serums to treat pigmentation.
Prevention is key - Use sunblock regularly and avoid excessive sun exposure as much as possible.
For more information on pico-laser treatments in Singapore.
Hope that this helps!
Warmest regards,
Dr Justin Boey
