A healthy diet is essential in winter
even more than the rest of the year. Sufficient vitamin C intake will not only boost your immune system, but also helps your skin looking radiant by supporting the production of collagen and limiting cells aging, as it is a strong antioxidant. Pepper, parsley, kiwi, citruses, and more broadly fresh fruits and vegetables, you've got a choice! Omega-3 (which can be found in fatty fish, nuts, flaxseed, rapeseed oil, etc.) also participates in making the skin smoother and more supple.
Although we generally tend to drink less water in the winter, our body needs hydration; so don't forget to drink up. As cold beverages might seem less appealing, you can try warm water with lemon, or tea.
