Vichy Aqualia Thermal Light 21 ingredients
Expensive. It’s not very light as it says. But I have combination skin and in the winter its pretty good. Doesn’t absorb very well. A bit of smell.

Doesn’t break me out. Lightweight perfect for humid climates. Doesn’t irritate my skin
Sticky texture. Got tiny pimples after applying on my dry skin. It's not irritating though even when put on the barrier-damaged areas.
