To maximize hydration and reduce acne, you can use a fragrance-free moisturizer such as Aveeno, Cutibase, Base Glaxal, or Cerave. It's important to apply the moisturizer whenever your skin feels dry, avoid using scented soaps, and gently pat your skin after bathing instead of rubbing vigorously. Make sure to protect your face in cold weather and apply sunscreen with at least SPF 30 30 minutes before going out, even in winter. These measures, along with other non-pharmacological steps, can help improve your skin hydration and acne.
