Girlies where do you all buy cosmetics from

There is soo much scam these days in the beauty industry and I'm fearing that if I buy something it'd turn out to be fake and harm my skin even more. Where do you buy your cosmetics like good quality make-up, toner, moisturiser, serum etc from? And is there any reliable shop I can go to ensure at least the products are real😭😭😭
