[Product Question] French skincare products

Does anyone have suggestions regarding affordable French skincare products like moisturizers, sunscreens and cleansers? I'm traveling to Paris in March for a work trip, and I usually stop at a Monoprix to grab a few things. I've browsed the skincare and cosmetics aisle before but didn't know what I should buy. I'm in my early 30s and have a light complexion and semi-sensitive skin.
