What are effective treatment options to get rid of a sunspot?
Topical lightening creams are a good way to start. Some degree of lightening will be achieved if used appropriately over a period of 3-6 months.
If that fails to give you the desired results, consider pigment laser treatment as this is effective in removing sunspots. You may wish to read more about this option which has been well covered in other parts of this forum.
A face-to-face discussion with your preferred aesthetic doctor will help you select the best treatment option based on your response to previous treatment, expectations, tolerability for treatment downtime, and cost considerations.
Hope this helps!
Another name for a sunspot is a solar lentigine. This is is a well-circumscribed 'coin-shaped' looking brown patch that is commonly found in sun-exposed areas, like the face and the arms. This type of pigmentation is at the top layer of the skin and is best removed using a Q-switch Nd:YAG laser. It can take 2-3 treatments for complete removal. Sometimes, I use the green light (511nm) from the Dual Yellow laser to remove the superficial pigmentation. The only downside with laser treatments is that sometimes hyperpigmentation from the laser treatment can develop after the procedure. This is temporary and is usually treated with lightening creams and sun protection.
