A place in your routine

Think about the whole routine

A firmness product should have a clear place in the routine and a realistic goal. Hydration, surface texture and substantial skin laxity are different outcomes and should not be promised as one result.

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 Copper Peptide Cream Rx.
