Prescription skincare compared, and getting through the purge

No affiliate links on this page. We earn no commission from any program listed, nobody paid to appear here, and the order is not for sale.
These services all supply prescription topicals, mostly built on tretinoin. What separates them is whether you get one ingredient at a strength you control or several combined into a custom formula, whether a consult is billed separately, and how cheap the first month is compared with the twelfth.
The reason this page exists is the adjustment period. Retinoids commonly cause irritation and a worsening phase before anything improves, often for several weeks. It is a predictable, documented part of the process, and it is also the point at which most people quietly stop.
Emerge Health AI does not prescribe and cannot assess your skin. It is a wellness app, not a medical device. What it does is keep the nightly record and answer the what-is-happening question with a source you can open, at the hour it actually bothers you.
These are numbered, not ranked. Each entry leads with the one thing it is factually best at. We do not score these programs on the quality of their clinical care.
01
Cheapest way to start
Curology
A custom formula combining tretinoin with one or two complementary actives, opening with a first box that costs only shipping.
A first box for shipping only, so the entry cost is negligible
Several actives combined into one nightly bottle
A per-patient formula rather than a fixed strength
Ongoing adjustments to the formula over time
What it leaves to you
The shipping-only first box is an entry offer, not the price. What you pay from month two is a different number.
Combining several actives in one formula makes it harder to identify which is responsible if your skin reacts.
Compounded products are prepared by a pharmacy rather than reviewed by the FDA for safety, effectiveness or quality before sale.
02
Control over strength
Apostrophe
Pure tretinoin at a specific strength you and the prescriber choose, rather than a blended custom formula.
One ingredient at a known strength, not a proprietary blend
A defined strength you can discuss and change deliberately
A single one-time consult fee rather than a recurring one
A formulation directly comparable to anything else on the market
What it leaves to you
A single ingredient means anything else your skin needs is a separate product you buy and manage yourself.
The $20 consult is paid before you know whether the service suits you.
Every price figure here is third-party sourced, because rates appear after an intake.
03
HSA and FSA accepted
Nurx
Prescription skincare inside a broader telehealth service, and the one here that takes HSA and FSA funds.
HSA and FSA funds accepted, which none of the others here publish
Skincare inside a broader telehealth catalogue rather than a single-purpose service
Standard prescription products at known strengths
No separate consult fee published
What it leaves to you
It is the highest ongoing monthly price of the three cheapest services here, and there is no entry offer to soften the first month.
Because skincare sits inside a wider catalogue, it is less specialised than the services that do only this.
Every figure here is third-party sourced.
04
Strongest multi-active formulations
Musely
Compounded multi-active topicals aimed at pigmentation and melasma as well as acne, at the highest price point here.
Formulations aimed at pigmentation and melasma, not only acne
Several actives combined into one nightly product
A $20 one-time consult rather than a recurring fee
The same account across its skin and hair programs
What it leaves to you
It is the highest ongoing price in this comparison, and a routine can involve more than one product.
Compounded products are prepared by a pharmacy rather than reviewed by the FDA for safety, effectiveness or quality before sale.
Stronger multi-active formulations mean the adjustment period can be more pronounced, and only you are present for it.
Common questions
Can Emerge Health AI prescribe tretinoin?
No. Emerge is a wellness app, not a medical device. It does not diagnose skin conditions, prescribe, or advise on strength. The services on this page are the ones that prescribe.
What is the difference between a compounded formula and single-ingredient tretinoin?
Curology and Musely compound tretinoin with additional actives into one custom formula. Apostrophe supplies tretinoin on its own at a strength you and the prescriber choose. A single ingredient is easier to attribute a reaction to; a combined formula is fewer steps. Neither is better in general, and which suits you is a question for the prescriber.
How long does the adjustment period usually last?
Retinoid adjustment, often called purging, is commonly described as lasting several weeks to a couple of months, with irritation and worsening before improvement. That gap is the most common point at which people stop. What the published sources say about your specific situation is worth reading, and Emerge will cite them rather than reassure you.
What should I track on prescription skincare?
Which nights you applied it, at what strength, and how your skin responded. When a formula contains several actives, a dated log is the only practical way to connect a reaction to a change.
How we compare
Services are compared only on facts that can be verified in public: what they prescribe, what they charge, whether a consult is billed separately, whether the formula is compounded or single-ingredient, and what the entry offer is.
We do not rate these services on results, and we do not compare formulations on effectiveness. Neither is a claim we are equipped to make.
Every figure is marked for how it was checked. A filled marker means it was read off that company’s public page. A hollow marker means it came from a dated third-party review.
Entry offers in this category are heavily promotional and change often, so the first-month price is rarely the ongoing price. Corrections to hello@getemergeapp.com.
Where Emerge fits, on any of them
Emerge cannot look at your skin, judge a reaction, or tell you whether to keep going. It is the nightly record and the cited answer during the weeks when it gets worse before it gets better.
Log each application and strength, so when something changes you can see exactly what preceded it rather than guessing.
Ask what a retinoid adjustment period is and get an answer citing MedlinePlus, NIH or Mayo Clinic, with the link, instead of a subreddit at 1am.
Keep a private journal through the weeks it looks worse, which is the stretch most people abandon and the one your prescriber most wants described.
Everything stays encrypted on your phone, on a system that keeps no conversation logs.
It will not tell you to stop, continue, or change strength. That is your prescriber’s call, and Emerge says so.
