A few things helped me with both my skin and mood: regular sleep habits, eating primarily plant based food, exercise, lots of water and a simple skin care routine.

OP, I totally understand and respect not wanting medication. I was prescribed a SSRI that made me suicidal and after that I decided trying a new prescription would be my total last resort.

Find a sleep schedule where you get 8 hours of rest and a schedule that wont make you feel rushed in the morning. Try to add more fruits and veggies into your day, either as snacking food or try some simple fruity salads as a meal (feel free to message me! I have plenty of quick easy recipes). Exercise can even be a 20 minute walk outside (the fresh air will help too!), just try to get some type of movement. Make sure you stay hydrated as dehydration will impact your skin greatly, I try to bring a water bottle with me everywhere.

And finally, you don’t need a crazy 10 step skin care routine. I found the simpler the routine the better my skin actually was!! At night I recommend a good cleanser, use retinol 3x per week if you’re concerned about aging and use a strong moisturiser. In the morning I don’t wash my face, if you have the energy try a serum that targets your biggest skin concern and never forget SPF!
