The Most Science-Backed Skincare Routine | Dr. Danny Guo

📖 Full written guide with sources: https://drdannyguo.com/library/routines Skincare doesn’t need to be complicated to work. In this video, I’m breaking down a simple, science-backed 4-step routine that covers 95% of what your skin actually needs without clutter, hype, or 10-step confusion. ✅ Step 1: Cleanser (remove oil, sunscreen, makeup, pollution) ✅ Step 2: Serum (pick actives based on your goal) ✅ Step 3: Moisturizer (barrier support = better results, less irritation) ✅ Step 4: Sunscreen (daily, SPF50, and broad-spectrum) If you master these four consistently, everything else is optional.
