The name covers multiple possible prescriptions
Custom Formula Rx is not a fixed three-ingredient recipe. Curology’s clinician chooses the actives after reviewing the patient’s information and photos. The page illustrates azelaic acid, clindamycin and niacinamide, among the possible options.[source]
Before comparing it with Pore Favor or a retail treatment, ask for the selected active list and concentrations. A product family cannot be evaluated as though every patient receives the example pictured on a webpage.
Each active should have a stated purpose
A combination may address more than one aspect of the concern. The useful question is why those particular ingredients were chosen, rather than whether three actives must be better than one.
If an antibiotic is included, ask the clinician about the treatment and reassessment plan. AAD discusses combination strategies within acne care; a review should not independently assemble or extend a prescription regimen.[source]
Read patient-reported results precisely
Curology’s page describes its short-term improvement claim as self-reported in a study of 150 patients. That does not establish that every customized blend produces the same response or that the service is superior to another treatment.[source]
We did not purchase a formula or assess before-and-after images as clinical evidence. The current prescription and follow-up are more useful decision points than an unqualified percentage.
Compare the recurring product charge
The page lists $29.95 monthly subscription and a $34.95 one-time option, with an introductory shipping-and-handling offer for eligible new subscribers. Confirm which arrangement is selected and when ordinary billing begins.[source]
Additional routine products can change the total cart. Separate them from the prescription when comparing quantities, care and ongoing cost.
A useful option when customization remains transparent
This product is relevant when a clinician-selected combination fits the concern and the reader wants continuing online follow-up. It is less straightforward to compare until the exact prescription is known.
FDA’s compounded-product distinction still applies to a custom preparation. Ingredient familiarity and personalization do not establish approval of every finished blend.[source]
