THE ONLY SCIENCE-BACKED SKINCARE ROUTINE YOU NEED (4 STEPS)
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.

Hi doc. I use like this: cleanser then azaelic acid then moisture then sunscreen.
I plan to add retinoid into my routine. I saw a bunch of your vedios but I couldn’t figure out how to incorporate retinoids into this routine. Can you help me with that?
Thank you.
do i really need sunscreen if im only exposed to the sun for 5 seconds a day..
Enjoyed this. Thank you,
Im an ethiopian teenager n i hv soo much discoloration over my face n body n also I’m more of a light skin but the years of sun we het have left me looking like im dark skin with discoloration any solutions for that(pls reply)
Finally a routine that skips the 12-step nonsense and explains the actual reasoning behind each product. Appreciate that you mentioned when things like retinoids are worth it versus overhyped.
