where do you cosmetic retailers guys keep finding authentic wholesalers coz for me its a Mess!!

Hi guys, help a bro out here !

I want to start selling international cosmetic brands like ceraVe, ordinary, Skin1004 in my own country using instagram but im totally new to this business I did some research on my own and I dont know where to start, I came across companies like q-depot and yesstyle but there wholesale price is quite alot with there limit to minimum quantity you can buy which is more than 100 units per order , I am run short of money and I also wanna sell in affordable price as I came across some pages who sell authentic products in lower price , ofcourse they wont share there secrets I ordered from this one page and there products are authentic as I used CheckFresh site to put the code from packaging and I got the manufacturer date and stuff plus the printing code on the package also looks real –dotted type; considering that the price they are selling is almost lower than the wholesale price of products on q-depot I asked them about it and they say its because they are wholesalers themselves and sell directly on there own page which is why they are able to sell at such a low price.

So, I came across another site called ‘globalsources’ where the wholesale price is very low but I read some concerns about its validity and authenticity while also learning about the facts that product might be original but might not be authorised by the original brand more like manufacturer stuff , should I go with them ? will I be fine , there are some badges granted by site itself to those sellers/manufacturers/wholesalers in ranking ordered like verified exhibitor, verified standard and premium legendary etc I did some research on the company info and came across nothing but some random news or maybe they are valid signs like one company is from uk and its trading brand name and the shareholder name is available on uk find-and-update site and another with its shareholder name and identity on linkedin with 120+ connections Idk if its a good sign or bad so just share some insights regarding anything.

I dont have much budget I can only manage upto 2-3k USD for now and upgrading it while doing this business as side to idk maybe main someday,hence, Im thinking of buying some authentic and low budget products that I can upgrade later which are also verifiable plus the cost of shipping and packaging and sites creation are another hustle that I gotta figure out on my own.

So, any advice or experience is appreciated.
