Hello Jacqua,
1. Acne Scars
Unfortunately acne scars, once formed, are a pain to get rid off. So I always advise my patient to worry about preventing new acne first, before bothering with their acne scars.
I’ve pretty much covered all there is to know previously about preventing and treating acne, as well as treating acne scars (click on link).
All topical creams ARE VERY limited in their ability to treat/get rid of scars once they are formed. My personal favourite is retinoic acid, but that’s mainly useful for making your face less oily, preventing new acne, and reducing the PIH (post-inflammatory hyperpigmentation, or the reddish/blue-purple discoloration left behind after a pimple pops). It has minimal effects on depressed scars that are already formed.
Some of the PIH (or redness) within the depressed scars will also fade on it’s own with time, typically at least 3-4 months later.
Hiruscar is not a cream that doctors use for acne scar treatment (or acne, for that matter). If you want to use a topical cream, you should use retinoic acid instead (available with a doctor’s prescription).
To get rid of your depressed scars, you will probably need some combination of fractional laser treatment and/or chemical peels/subcisions, depending on the severity and type of your acne scars.
2. Pigments
If they were left behind after a pimple went away, this is also probably due to PIH (see above).
All things considered, I think to properly have your acne scars assessed and treated, you need to see a doctor. In Singapore, you can seek out either a dermatologist, or an aesthetic doctor with an interest in treating acne scars.
Cheers
