AB sunscreen disappoints

I was gifted the AB sunscreen spf 50 by my MIL. Tried it on, and immediately had a disappointing experience. As usually advised, I only stepped out once it had been 15 mins post application. Next thing you know, the sunscreen starts dripping down with my sweat?? I’ve never experienced this with lower priced brands.

Sick and tired of brands justifying their premium purely on positioning and not actual product superiority. Also annoyed with the Eurocentric approach with formulation. This product is clearly not suitable for tropical climates.
