Curology
One product assessed so far. It publishes its inactive list like the sibling brand, but drops the fill weight — and it puts a topical antibiotic in a system with no benzoyl peroxide in it anywhere.
MODEL
Provider consultation, personalised compounded formula, monthly subscription. Parent of Agency, which handles the anti-ageing range.
The brand verdict
We have assessed one Curology product, so this is a note rather than a pattern analysis. It shares the group's best habit: a published inactive ingredient list, including the detail that dexpanthenol formulas contain propylene glycol.
The gap on DayPrimeRx is that no concentration is published for any of its six candidate actives — and reading the rest of the catalogue makes that harder to defend rather than easier. Custom FormulaRx names niacinamide at 4%, azelaic acid at 8% and clindamycin at 1% on the product page. HydroTretRx names tretinoin at 0.02%, azelaic acid at 5% and dexpanthenol at 1%. This company can put concentrations on a personalised formula's page, because on two other pages it does. The acne-plus-primer product is the one that does not.
DayPrimeRx is a genuinely clever piece of product design — a prescription acne treatment that is also a working cosmetic primer, with the optical agents identifiable in the published list rather than asserted. Ceramide NP in an acne formula is a good sign about who wrote it.
Two things stop it scoring higher. Clindamycin phosphate sits in the candidate pool and there is no benzoyl peroxide anywhere in this system — the paired night routine supplies a retinoid, which is a recommended combination, but benzoyl peroxide does the different job of protecting the antibiotic and it is simply absent. And zinc pyrithione, another candidate active, has been prohibited in EU cosmetics since 2022 on a reproductive-toxicity classification, which the page does not mention.
One regression is worth flagging across the group: the sibling brand publishes fill weights in grams on every product, and this one does not.
- Publishes a full inactive ingredient list, including which formulas contain propylene glycol.
- Publishes active concentrations on two other pages in the catalogue — niacinamide 4%, azelaic acid 8%, clindamycin 1% on Custom FormulaRx; tretinoin 0.02%, azelaic acid 5%, dexpanthenol 1% on HydroTretRx. It can be done on a personalised formula, and here it is done.
- The blurring claim is backed by identifiable optical agents in that list rather than by adjectives.
- Ceramide NP in an acne product — barrier thinking in a formula designed for daily wear.
- A six-active candidate pool lets a provider match mechanism to presentation.
- States a realistic six-to-twelve-week timeline and makes no inflated percentage claim.
- Correct sequencing advice that puts sun protection ahead of the cosmetic effect.
- $29.95 a month is the cheapest prescription product in this register, doing two jobs.

DayPrimeRx
ACNE TREATMENT + BLURRING PRIMERA prescription acne treatment that is also a genuine blurring primer, and the optical agents are right there in the published ingredient list. Two things to know: there is no benzoyl peroxide anywhere in the system, and one candidate active is prohibited in EU cosmetics.

What repeats across the range
These are the findings a single review cannot make. Each one appears in more than one product, and each is drawn from the reviews above rather than from an impression of the brand.
- 01
The group's disclosure habit, minus the fill weight
Full inactive list published, with irritant caveats — consistent with Agency. But where Agency publishes 12 g and 18 g, this page gives a 30-day supply and no weight, so cost per application is not computable. Same parent, same pharmacy, less information.
- 02
An antibiotic with no benzoyl peroxide in the system
Clindamycin phosphate is a candidate active and benzoyl peroxide appears nowhere in the product or the pool. The paired night formula supplies a retinoid, which is a guideline-recommended combination — but benzoyl peroxide is the specific agent that suppresses resistant organisms during treatment, and it is missing from the whole routine. It is missing from the catalogue too: the company's prescription acne body wash, the format where a benzoyl peroxide wash would naturally sit, runs sulfacetamide, zinc pyrithione and salicylic acid instead. Two antibacterials across the range and no benzoyl peroxide behind either.
- 03
A contested ingredient, named without context
Zinc pyrithione is in the candidate pool, and it is in the body wash as well. It is legal in the US and prohibited in EU cosmetics since March 2022 on a CMR 1B reproductive-toxicity classification — a classification decision rather than a new safety finding, and one made about rinse-off shampoo rather than leave-on facial use. The split is worth a sentence and gets one on neither page. One omission is an oversight; the same omission twice is a house style.
- 04
The concentrations exist on some pages and not others
Custom FormulaRx publishes niacinamide 4%, azelaic acid 8% and clindamycin 1%. HydroTretRx publishes tretinoin 0.02%, azelaic acid 5% and dexpanthenol 1%. DayPrimeRx publishes none for its six. The same bundle page that sells HydroTretRx also drops its numbers, so the disclosure varies by page rather than by product — the pattern we charged another company with when its concentrations lived in a help centre, except here both versions are product pages.
- 05
One vehicle across two brands
Custom FormulaRx and HydroTretRx publish the same inactive list as Agency's Future Formula, ingredient for ingredient — aloe, C13-14 isoparaffin, caprylic/capric triglyceride, water, laureth-7, phenoxyethanol, polyacrylamide, tocopheryl acetate, triethylene glycol — with BHT added to tretinoin formulas and propylene glycol to the dexpanthenol and niacinamide-plus-azelaic ones. Same base, same caveats, two brand names. DayPrimeRx is the exception, and it is a different formula built for daily wear.
- 06
A retinoid dosed just under the trial range, published honestly
HydroTretRx's tretinoin is 0.02%. The photoageing trial literature starts at 0.025%, so this sits fractionally below the evidence — but it is on the page, in a number, which is more than any other tretinoin product in the register manages. Under-dosed and disclosed is a different failure from correctly dosed and hidden, and it is the better of the two.
- 07
A sulfonamide with no allergy warning, and no price at all
Body CleanseRx is built on sulfacetamide — a sulfonamide, and sulfa hypersensitivity is one of the more common drug allergies there is. The page's only caution is that dryness and irritation may occur. It also states neither a price nor a fill volume, only a 30-day supply, which is a step below the rest of the catalogue. Credit where it is due on the other side: it does name a side effect, tells you to work up to daily use, and gives a 30-second contact time — which for a rinse-off active is the instruction that decides whether it does anything.
Disclosure scorecard
Not what is in the product — what the company publishes about it, and where. “Findable” means the concentration exists somewhere, such as a help-centre article, rather than on the page you buy from.
