Q: What medications should I avoid while using retinol?

A: Certain medications increase retinol sensitivity: 

• Photosensitizing drugs: Antibiotics (tetracycline, doxycycline), some diuretics 

• Topical medications: Benzoyl peroxide, salicylic acid (separate timing required) 

• Blood thinners: May increase skin fragility and healing time 

• Chemotherapy drugs: Must consult oncologist before using any active skincare products 

• Always disclose: Inform both dermatologist and prescribing physician about skincare routine 

• Timing matters: Some combinations are safe with proper spacing
