Will my skin be very dry if I only use Laneige Cream Skin as a basic skincare product?

I have combination skin, and the weather has been so sticky lately that even applying cream feels like a hassle. I saw an ad for Laneige Cream Skin where you spray it on like a mist and then pat it in to help with absorption; it looks like it would be convenient to just use that, so I'm really tempted. Even if it's not Laneige, there are many brands that produce Cream Skin; for those who have tried them, is the moisturizing effect good?
