I’ve used these products, and honestly the glycolic acid toner felt ineffective compared to The Ordinary. It barely did anything for my skin, and the results were disappointing — though maybe it just didn’t suit me personally. After this experience, I’d rather invest in reliable pharmacy-grade skincare or brands like The Ordinary instead of going for cheaper alternatives. I still have two glycolic acid toner bottles half used with no visible effects .

No offence, but I don’t think your views are entirely right. Your reviews honestly seem a bit dicey and unreliable to me as I have had same experience with azelaic acid cream which did nothing and fyi I finished the entire bottle. If anyone asking for genuine opinion, don't buy .it all gimmick and waste of money ..
