I have finished 2 bottles of these. When using it for the first 30 days, i wasn't seeing dramatic results as expected, i think this was because i used fresh herb serum (which had some vitamin c) after applying this toner. but then i found out niancinamide and vitamin c cancel each other out. so when using the second bottle, i started to actually see results this time. my skin brightened and pigmented scars slightly faded. i was also using the snail mucin essence from cos rx with this product.
the only thing is you HAVE to be consistent, like you must use it 2 times a day everyday to see results. AND WEAR SUNSCREEN!!
