Our reading of the offer

Compare the right things

Hormone-containing facial products need a hormone-aware assessment. Cosmetic goals do not remove the importance of medical history, other hormone medicines or uncertainty about the finished compounded preparation.

Context: AAD pregnancy skincare guidance ↗ · FDA on compounded medicines ↗.

Compounded is a distinct category. This finished preparation is not FDA-approved. Approval or research involving an individual ingredient does not establish approval, safety or effectiveness of this exact blend.

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 Alloy M4 Body Treatment Rx.
