🛡️ Protection

1. Mineral Sunscreens with Iron Oxide

   • Zinc oxide or titanium dioxide + iron oxides help block visible light (including blue light)

   • Look for “tinted mineral sunscreen” (e.g., EltaMD UV Elements, Colorescience, La Roche-Posay Tinted SPF)

2. Antioxidants (AM Use)

   • Vitamin C, niacinamide, green tea, or resveratrol

   • They help neutralize free radicals caused by blue light

3. Screen Settings

   • Use “night mode” or blue light filters on devices

   • Reduce screen brightness when possible

🧴 Repair and Recovery

1. Evening Routine

   • Apply barrier-repairing ingredients like:

     • Ceramides

     • Hyaluronic acid

     • Peptides

   • Use retinoids or bakuchiol to help with collagen renewal if skin tolerates them

2. Niacinamide

   • Helps reduce inflammation, even tone, and strengthen the skin barrier

3. Licorice Root Extract or Tranexamic Acid

   • Target blue-light-induced hyperpigmentation and melanin overproduction

🧘 Lifestyle Tips

• Limit screen time before bed

• Use physical distance from screens—more distance = less light exposure

• Sleep in a dark room to promote natural repair cycles
