About Winter 2023-24 Routine

Our winters are cold and dark with sub-freezing temperatures, very dry air & next to no UV. Focusing my skincare largely on hydration, moisturization and barrier support while keeping my regular anti-aging actives in use, although at a lower intensity. Sunscreen generally isn't necessary, as the sun is only up for a couple of hours a day and even during that time the UV index is 0.

Rotating my glycolic and high-concentration azelaic acids according to the following cycle to prevent barrier damage which I'm pretty prone to in general but especially so when the air is as dry as it is. Day 1: 5% glycolic acid (PM) Day 2: (rest) Day 3: 20% azelaic acid (AM)
