Does C'est Moi Sunshine Mineral Sunscreen leave a white cast?
White cast is rated medium, so a faint cast may show on deeper skin tones, since it uses zinc oxide. The finish is balanced.
Does the C'est Moi Sunshine Mineral Sunscreen Lotion Broad Spectrum Spf 45 Water Resistant work under makeup?
It is rated poor as a makeup base, so it is better worn on bare skin. It is water resistant, which suits outdoor and body use.
Is C'est Moi Sunshine Mineral Sunscreen SPF 45 any good?
It scores 69.4/100, a fair result. Protection is rated moderate with low sting and low breakout risk, best suited to bare skin rather than under makeup.
