The treatment of pigmentation depends on its location (e.g., dermal vs epidermal) and type (e.g., age spots, melasma, etc). The basic rule where prevention is better than cure applies, this means that sun block is a must.
For pigmentation treatment options in Singapore, there are a variety of topical treatments available. Lasers and other energy based procedures can also help improve pigmentation but typically require a few sessions. Often topical AND energy-based treatments are commenced at the same time.
