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 ↗.

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

This compounded product is not FDA-approved. Discuss the uncertain benefit-risk evidence for the finished topical combination.

  • 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 Musely The Cell Repair Serum.
