@drjennyliu: For TikTok, I’d make the caption itself the mini cheat sheet so people can save it. Not quite as long as the ManyChat guide, but enough to be genuinely useful: How I’d actually start tretinoin + azelaic acid together: WEEKS 1–4 AM: Azelaic acid every other morning → moisturizer → SPF PM: Tretinoin 2x/week → moisturizer THEN, IF YOUR SKIN IS HAPPY AM: Azelaic acid every morning PM: Increase tretinoin to 3x/week → gradually work up as tolerated MORE ADVANCED / WELL TOLERATED AM: Azelaic acid PM: Azelaic acid → tretinoin → moisturizer You do NOT have to reach that last step. Sensitive skin can stay with azelaic acid AM + tretinoin PM long-term. A few rules: • Pea-size tretinoin for your entire face • Apply tretinoin to dry skin • 10% azelaic acid is a reasonable OTC starting point • Azelaic acid can irritate too • Increase ONE thing at a time • Burning, significant redness or excessive peeling = back off • SPF every morning Start low. Go slow. Consistency > irritation. Topical retinoids are generally avoided during pregnancy. Thanks @Zimma for sharing #azelaicacid #tretinoin #dermatologist #skincaretips #skincareroutine
