Hello madam...
You have grade-2/3 Acne with more of comdones.. as you mentioned about your skin being sensitive that means one should understand that and prescribe creams/ cosmetics / daily routine stuff accordingly... Tretin cream though a good cream for acne it’s better avoided on sensitive skin as it can dry the skin
Next Steps
Consult a qualified dermatologist to understand your skin and treat accordingly and give you a proper maintenance for daily routine
Health Tips
Always don’t mix too many products on your face as can give breakouts... choose products suitable for acne prone skin which are non comedogenic suggested by dermatologist.. simultaneously get your dandruff/ seborrhic dermatitis treated
Take care
