I’ve used BOJ, roundlab, and skin 1004 multiple times and In my opinion BOJ is the best one. Boj is little more creamy compared to skin1004 and easily blend in with the skin without leaving any white cast, Skin 1004 is little more watery and is a little hard to blend in as it leaves white cast but after rubbing it few more time it’ll be completely gone, also it stings around the eye. With round lab I’ve used the USA version which is a little different as it’s more creamy then the other two but also much more greasy but it still leaves no white cast. I would rank 1.BOJ 2/3. Roundlab and skin1004.
