Certain #foods can help your skin glow from the inside out, so make sure you eat plenty of fish like salmon and tuna (high in omega-3 helping skin with collagen production), spinach and avocadoes (high in vitamin E, protecting skin from UV rays and cell damage) + vitamin C-rich foods like tomatoes and citrus fruits (they'll help stave off wrinkles). Sugar won't be doing any favours for sallow winter skin, so snack on seeds/ nuts for a zinc boost, essential for preventing rashes and irritations.
