What exactly is the product?
CoreAge Rx Pore Favor
Pore Favor: compounded prescription cream; new offer states salicylic acid 2%, zinc oxide 5%, niacinamide 8%, urea 2%.
Full review ↗Differin Adapalene Gel
Differin: an OTC gel containing 0.1% adapalene, a retinoid for acne. Other Differin products are separate.
Full review ↗Paula’s Choice 2% BHA
Skin Perfecting 2% BHA Liquid Exfoliant: a leave-on liquid. It is not a cream or rinse-off cleanser.
Full review ↗La Roche-Posay Effaclar BPO
Effaclar BPO Multi-Target: 5.5% benzoyl peroxide. This is not the discontinued Effaclar Duo or the salicylic-acid Multi-Target product.
Full review ↗The Ordinary Azelaic Acid 10%
Azelaic Acid Suspension 10%: a cream-like appearance product for tone and texture, not a salicylic acid cream. Prescription azelaic acid preparations are separate.
Full review ↗The INKEY List BHA Serum
Beta Hydroxy Acid Serum: a 2% salicylic acid OTC acne product with a 30 mL bottle record. Different from the brand’s 360° serum.
Full review ↗PanOxyl 4% Creamy Wash
Acne Creamy Wash: declared 4% benzoyl peroxide, rinse-off, 6 oz (170 g). Not a leave-on moisturizer or the 10% Foaming Wash.
Full review ↗Epiduo Forte
Epiduo Forte: prescription adapalene 0.3%/benzoyl peroxide 2.5% gel for acne age 12+. Separate from lower-strength combinations and OTC adapalene.
Full review ↗What does the offer cost?
CoreAge Rx Pore Favor
12 months $504, displayed $42/month; six months $300, three months $168 or one month $70. Rounded unit displays differ from exact division. Confirm current prescription supply and terms.
Full review ↗Differin Adapalene Gel
Direct retail price not established. The manufacturer lists several 15 g and 45 g packages; confirm the selected seller and size.
Full review ↗Paula’s Choice 2% BHA
$37 for 4 fl. oz. as a one-time purchase. $31.45 is the separate subscription offer; confirm delivery interval and current terms.
Full review ↗La Roche-Posay Effaclar BPO
$24.99 for the selected 20 mL size in accessible official-page text. Direct access was blocked; verify the current cart and shipping.
Full review ↗The Ordinary Azelaic Acid 10%
Selected 30 mL US variant: $10.98 reduced from $12.20. A temporary container-price snapshot, before checkout charges.
Full review ↗The INKEY List BHA Serum
US $14 for 30 mL. Shipping from $7.95 with regional variation and threshold terms; no guaranteed delivered total.
Full review ↗PanOxyl 4% Creamy Wash
No direct manufacturer checkout price established. Compare the exact retailer, 6 oz package and final total; no measured monthly consumption.
Full review ↗Epiduo Forte
Current cash price, copay, coupon eligibility and pharmacy stock not verified. Label package sizes do not establish available inventory.
Full review ↗What does the evidence establish?
CoreAge Rx Pore Favor
Provider-published concentrations and care process; no complete-formula comparative trial established. Compounded drugs are not FDA-approved.
Full review ↗Differin Adapalene Gel
A defined OTC acne medication and a specific FDA approval history. That does not establish permanent pore erasure or suitability for every reader.
Full review ↗Paula’s Choice 2% BHA
Manufacturer study footnotes for selected outcomes. Full protocols and an independent comparison against the other offers were not appraised.
Full review ↗La Roche-Posay Effaclar BPO
Manufacturer clinical and consumer summaries with qualifications, including a subgroup versus average distinction. These are not a universal promise of results.
Full review ↗The Ordinary Azelaic Acid 10%
Manufacturer appearance claims and formula-format information. No independently established superiority or prescription equivalence for this exact suspension.
Full review ↗The INKEY List BHA Serum
Submitted acne label plus manufacturer hydration claims. Hyaluronic acid does not cancel the dryness warning; multi-product stories cannot isolate this serum’s effect.
Full review ↗PanOxyl 4% Creamy Wash
Manufacturer claims and submitted acne label, without a full exact-product controlled-trial appraisal. Gallery examples for other products are excluded.
Full review ↗Epiduo Forte
Twelve-week trial: IGA success 33.7% vs vehicle 11.0%. Not designed or powered to prove superiority over the lower-strength combination; not a scar or pore-erasure endpoint.
Full review ↗What still needs checking?
CoreAge Rx Pore Favor
Full base, actual dispensed formula and quantity, eligibility, selected total, follow-up and cancellation details. Nonapproval refund is not a blanket satisfaction refund.
Full review ↗Differin Adapalene Gel
The exact current package and leaflet, whether the concern is acne, retailer terms and compatibility with the existing routine.
Full review ↗Paula’s Choice 2% BHA
The exact liquid format, purchase type, full ingredient list and how an exfoliant fits with existing skin care.
Full review ↗La Roche-Posay Effaclar BPO
The current product name and size, full warnings, live offer and the practical possibility of irritation or fabric bleaching.
Full review ↗The Ordinary Azelaic Acid 10%
Exact current package, the concern being addressed, manufacturer compatibility guidance and clinician instructions where a prescription is involved.
Full review ↗The INKEY List BHA Serum
Current label versus older submitted record, existing acne medications, irritation response, complete price and product identity.
Full review ↗PanOxyl 4% Creamy Wash
The 4% Drug Facts declaration conflicts with a separate 58.7 mg/g structured field. Inactive lists and frequency text also differ; confirm the current package with a pharmacist or manufacturer.
Full review ↗Epiduo Forte
Exact prescription, package, contraindications, irritation and hypersensitivity warnings, sun precautions and other medicines. Clinical fit requires the prescriber.
