I typically use a separate SPF product to have better control of my skincare routine and reliable SPF coverage. However, due to recent changes in my schedule I have been tempted to use day creams with integrated SPF for convenience. I have started with La Roche Posay's Hydraphase Intense UV which claims to have SPF20. Additionally, I practice all other sun safety measures.
My main concern is, how do I know how much to use? Do I dispense the same recommended quantity as sunscreens? Is it safe to use the same amount I would use for a moisturiser? Is this form of sun protection reliable at all?
