For those of us with sensitive skin, it can be a bit like playing Russian roulette trying out new products. “Will this product brighten my skin or am I going to end up looking like a prize tomato?”.
To avoid this, there’s actually a pretty simple fix. Before you go full face, test the product first on a patch of your skin. Somewhere small where you’ll be able to deal with it but large enough where you’ll be able to tell if things go wrong.
Everyone is different, and it may take as little as a few minutes(if you’re allegric) to days to react to a product. So depending on your level of sensitivity, its usually best to patch test for a few days at least before going full face.
