I recommend the About Tone Blur Powder Pact, a base makeup product I bought with my own money.

Makeup is prone to ruining in the summer due to heat and sweat. Even when using loose powder, it used to clump and look patchy in certain areas. However, after switching to the About Tone Blur Powder Pact, it applies evenly and thinly without caking or clumping, leaving a matte and soft finish that doesn't transfer onto a mask. I recommend shade #1 for those with shade #21 skin. Even as someone with dry skin, I recommend it for summer makeup as it doesn't feel dry or heavy.
