Yes if you know the tricks and are well-aware of the market you can make a good profit in the buy-sell makeup business. There is a lot of demand for original and good-quality makeup. Especially in countries where the official brand stores are not present. However, that will also include import/export and you will need knowledge and capital for that as well. All in all, it is a great business idea and if you have the means, you most definitely should give it a try. However, the most major trick is to keep the prices low and not too high. It does not mean you don't keep any profit, but rather keep it low. At least in the beginning.
