I think I've been using this product for at least six months now and there's definitely a huge difference. I've been having trouble with acne practically my whole life, and acne scars and blemishes are no joke. Instead of a nice red blush, I'd have dark acne scar spots all over my cheeks. at first I was sort of skeptical, though, it certainly works. of course it needs a little bit of time with your skin and i assure you it'll brighten your skin. I used to apply a whole slab on my face but I learned that a little bit is enough. Just place it on top of the scar/blemishes and it will definitely lighten them slowly. You might not see the progress now, but you'll see it in a few months.

First impression : Wow. The HA benefit is real , make my skin bouncy n hydrated. For brightening its clear up post hyperpigmentation, not for erythema issue. Takes time for clearing up , maybe 2 month or 3. Great texture , easily absord. Highly rec. for dry and oily skin as well

I feel like i haven't had much luck with the ordinary despite how hyped it is. My mum bought this for herself and i decided to try it for myself one day, as i am still searching for the perfect product to take care of my hyperpigmentation. After using it only ONCE at night, it gave me cystic acne and i only every get cystic acne if a product disagrees with me. Never using this ever again.

I used this product for about 3 months but unfortunately did not see any difference in my acne scars. I think it did help brighten my overall skin tone a bit but nothing to write home about.
PROS: Nice texture, sinks into skin very fast and dries down like nothing, doesn't break me out.
CONS: doesn't do anything for acne scars.
