Physiogel is truly a year-round essential. I have been consistently using only the blue one. I haven't tried the red one; is it good? The blue one is really great; it isn't heavy, is moisturizing, and is suitable for applying anytime, even in the summer. It doesn't dry out my skin at all, even in the winter. It is a product I always need; I feel anxious without it, so I stock up on a few whenever it goes on sale.
