The practical assessment
Questions that change the decision
Ask which claim has evidence for the finished formulation, how change will be judged and when to reassess. Cosmetic repair language should never be treated as instructions to manage a wound or undiagnosed skin disease.
Context: AAD pregnancy skincare guidance ↗ · FDA on compounded medicines ↗.
Before starting or switching
Ask the prescriber to review allergies, pregnancy or breastfeeding, other medicines and the exact treatment area. Follow the dispensed label and seek advice for significant irritation.
- What exact ingredients, strengths and dosage form will I receive?
- What is the full first charge, quantity, refill schedule and cancellation policy?
- When should treatment be reassessed, and how do I contact the clinician?
These are questions for a licensed clinician, not instructions to start, stop or change a prescription. Read the product’s complete safety information.
CoreAge Rx is placed first because it is this publication’s promoted recommendation. No head-to-head clinical testing supports a claim that it is better or safer than Agency Day Defender Rx.
