Hi Ching Tan,
It is true that freckles are related to genetic factors and can be aggravated by excessive sun exposure.
The best way to remove freckles is with pigmentation lasers (eg Q-switched Nd Yag laser).
You can expect downtime of redness of 1 day followed by dry scabbing for 5-7 days, with a couple of laser sessions. This downtime can be readily concealed, so you can still resume your daily activities.
Sun protection measures before and after the laser sessions are equally important for sustainable results, otherwise the freckles can slowly recur.
So I would recommend you to speak to an experienced doctor in treating pigmentations with lasers to discuss on the most suitable treatment options for you.
If you are keen for more detailed information on treatments of freckles (including photos of the expected downtime) and also other common types of pigmentations, you can find out more in my "Ultimate Guide to Pigmentation Treatment in Singapore".
Hope this helps!
Cheers!
Dr David Ng C H
