I recommend the Lindsay Modeling Pack.

This is the Lindsay Cool Tea Tree Modeling Pack. In the summer, the sun is scorching and the weather is hot, so your face feels instantly flushed; this is an absolute must-have on days like this.

I bought the large 1kg size, so it's great value for money. It provides a proper cooling effect, so I tend to use it often. You are supposed to mix the powder with water (ampoule) in a 1:0.8 ratio, but I personally make mine with half water and half ampoule.

My routine is to apply toner and a vitamin ampoule before the mask, and then finish with a moisturizer after the mask.
