How big is the bottle for a 7-day trip?

Hello, it is a very troublesome problem to carry skin care products and cosmetics when traveling abroad. So how big does it take to divide the bottles, which can last just seven days? In fact, it mainly depends on your daily usage, so in order to protect your skin every day, bring as much as possible.

There are 15ml, 30ml, 50ml and 100ml bottled separately. It is recommended to bring 30ml of milk and cream for a 7-day trip, because the amount of cream is less each time, and the water can be 50 or 100 according to your own usage habits, and it is more useful to bring more water.

Seven days is neither too long nor too short, and skin care products are mainly accurate according to their own usage habits.
