Laura Mercier Tinted Moisturizer for allergic skin?

I always have the fear that my skin will react  and start getting blemishes if i use moisturizer without knowing enough about it so that i can trust it . I love decking myself up while going out. So my close friend who knows a lot on beauty products told me about Laura Mercier Tinted Moisturizer for me . will Laura Mercier Tinted Moisturizer give a lighter or a more duskier tone to my face? Is it fine if i use it for my Allergic skin?Will  Laura Mercier Tinted Moisturizer react on my skin and does it act as a make up agent or is it a simple moisturirizing cream giving it a amazing glow?
