The purchasing decision
Look beyond a monthly number
Price per month is incomplete without quantity and refill terms. Avoid paying for an assumed clinical advantage based only on a higher peptide concentration or a more elaborate ingredient name.
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.
