Dear Brightly / Night Shift Rx
TAILORED TRETINOIN 0.015–0.089% + NIACINAMIDE
A water-free silicone elastomer base with the full ingredient list published, a tretinoin range printed on the page, and a mandatory auto-refill plan justified by a claim about retinisation that the company's own shipping schedule contradicts.

The verdict
The formulation disclosure here is better than most of this register. The FAQ publishes the entire base — ST-Elastomer 10, Q7-9120 silicone fluid, EL-7040 hydro elastomer blend, vitamin E acetate, polyglycerol-3 diisostearate — alongside niacinamide and tretinoin. There is no water in it. An anhydrous silicone elastomer vehicle needs no preservative, spreads thinly and slows delivery, which is a reasonable design for a nightly retinoid on skin that has not had one before.
The strength range is published too: 0.015% to 0.089%. That is genuinely more than Musely, Dermatica or Curology tell you before you buy. But the bottom of the range sits below 0.025%, the floor of the tretinoin trial literature, and the top is an oddly precise 0.089% that corresponds to no approved product. You are told the range; you are not told your number until the prescriber sets it, and the page does not say what determines it beyond a photograph and a questionnaire.
The subscription is compulsory. 'Right now, we only have an auto-refill plan with an option to cancel anytime.' The justification given is retinisation: stop for longer than about four weeks, the FAQ says, and 'you'd have to start all over, and your skin would have to re-adjust to the product.' That is a real phenomenon stated as a stronger claim than the evidence supports, and it is being used to explain why continuous billing is necessary.
It also does not survive contact with the company's own logistics. A refill is a three-month supply and refills ship 'every 3 or 4 months' — so a customer on the four-month cycle runs dry for roughly a month, by the schedule Dear Brightly sets, for the exact reason Dear Brightly says makes stopping harmful. Either the retinisation argument is overstated or the shipping option is wrong. Both cannot hold.
- Publishes the complete base ingredient list, which most of this register does not.
- An anhydrous silicone elastomer vehicle — no water, therefore no preservative required.
- Publishes the tretinoin strength range before purchase: 0.015% to 0.089%.
- Publishes trial and refill pricing, supply durations and shipping cadence.
- States that a starter strength may be used before stepping up, and that the treatment plan shows the strength.
- Consistent $33 a month across trial and refill, with no hidden step change.
- Cancellation is available at any time, including during the trial.
- Sells a separate zinc oxide 10% sunscreen with its full ingredient list published — the right adjunct for a retinoid user.
- The bottom of the strength range, 0.015%, is below the tretinoin trial floor.
- Your individual strength is not disclosed until after purchase and consultation.
- Niacinamide is a headline ingredient with no published concentration.
- No container size anywhere, so cost per application is incomputable.
- Auto-refill is compulsory; there is no one-off purchase.
- The retinisation justification for mandatory billing overstates the evidence.
- Refills are a three-month supply but ship every three or four months, creating a gap the company's own argument says is harmful.
- No antioxidant system described for a light- and oxygen-sensitive active.
- No pregnancy guidance found on the product page for a retinoid product.

- Tretinoin0.015% – 0.089%
Retinoid — the entire therapeutic basis of the product
- BENCHMARK
- 0.025% to 0.1% across the trial literature; 0.02% for the approved wrinkle indication
- ASSESSMENT
- A range spanning nearly sixfold, published on the page, with the individual figure assigned after consultation. The upper end is respectable. The lower end sits below every concentration the acne literature has tested and below the 0.02% at which the approved photoageing product was trialled, so a customer started at 0.015% is below the evidence base in both indications and has no way to know it from the page.
- NiacinamideNOT PUBLISHED
Anti-inflammatory, barrier support, reduces redness alongside a retinoid
- BENCHMARK
- 2–5% is the usual effective range
- ASSESSMENT
- Named prominently in the marketing — 'the dynamic duo of Tretinoin and Niacinamide' — with no concentration anywhere we could find. Given that the tretinoin range is published, omitting the niacinamide figure looks like an oversight rather than a policy, and it is the easier of the two numbers to publish.

Scoring
- EVIDENCE FOR THE ACTIVEWEIGHT 30%60/100
Tretinoin has a genuine evidence base for photoageing and this product is built around it. Marked down because the assigned strength may sit below the trialled range, because the combination with niacinamide at an unpublished concentration has never been tested, and because the page cites no trial of its own — the claims rest on the class.
- FORMULATION INTEGRITYWEIGHT 20%68/100
A water-free silicone elastomer base is a considered choice: no preservative required, thin even spread, slowed release. The full base composition is published, which almost nothing else in this register does. Held back because niacinamide is unquantified, no antioxidant system is described for a light-sensitive and oxygen-sensitive active, and no container size is given.
- DISCLOSUREWEIGHT 15%58/100
Publishes the full base ingredient list, the tretinoin range, the trial and refill pricing, the supply durations and the shipping cadence — all above average for this register. Undercut by an unpublished niacinamide concentration, no container size, no individual strength before purchase, and a retinisation claim used to justify mandatory billing that the company's own refill schedule contradicts.
- TOLERANCE IN USEWEIGHT 15%NOT ASSESSED
Not assessed. The anhydrous elastomer base is a tolerability play and the low starting strengths are another, so this is the criterion the product is designed around — and the one with no published data.
- TEXTURE & WEARWEIGHT 10%NOT ASSESSED
Not assessed. Silicone elastomer bases have a distinctive slip and a tendency to pill under other products, which a panel would settle.
- COST PER APPLICATIONWEIGHT 10%55/100
$66 for a two-month trial and $99 per three-month refill both work out at $33 a month, which is fair for a prescription retinoid with clinician access. But no container size is published anywhere, so cost per application cannot be computed and the supply claims cannot be checked.
What it is
A compounded nightly tretinoin serum with niacinamide, prescribed after an online consultation and photographs, sold only on an auto-refill plan. $66 for a two-month starter bottle, then $99 per three-month refill — $33 a month either way.

Night Shift: Niacinamide, Tretinoin (strengths range from 0.015% to 0.089%), Base: ST-Elastomer 10, Q7-9120 Silicone Fluid, EL-7040 Hydro Elastomer Blend, Vitamin E Acetate, Liquid, Polyglycerol-3 Diisostearique
Dear Brightly FAQ
No water. Three silicone elastomer components, a silicone fluid, vitamin E acetate and an emulsifier. This is the second anhydrous prescription vehicle in the register, after the rosacea cream at R-33, and the reasoning is the same: with no water phase there is no microbial growth, so there is no preservative, so there is one fewer category of irritant on skin about to be exposed to a retinoid.
Silicone elastomers also spread very thin and release slowly, which suits a nightly retinoid for a first-time user. Publishing the whole base — brand names of the raw materials included — is more than Musely, Dermatica, Agency or Curology do. It deserves saying before the criticism starts.
Niacinamide is the second half of the product's own marketing — 'the dynamic duo of Tretinoin and Niacinamide' — and its concentration appears nowhere. It is the easier figure to publish: unlike the tretinoin, it does not vary per patient. A company that will print ST-Elastomer 10 and EL-7040 by trade name and give the retinoid range to three decimal places has no obvious reason to omit it.
The range, and where its floor sits
Tretinoin concentrations as a percentage. The acne trial literature runs from 0.025% upward; the approved photoageing product was trialled at 0.02%. Dear Brightly's range extends below both, and the individual figure is set after purchase.
The ceiling is fine. The floor is the issue: someone assigned 0.015% is receiving a concentration below anything the literature has tested for either acne or wrinkles, and the page gives them no way to know that. To the company's credit, the FAQ states that a provider may deliberately start at a lower strength and ramp up, and that the treatment plan shows the current strength. The information exists after purchase. It simply is not the thing you can check first.
The compulsory subscription, and the argument for it
We offer an auto-refill plan because dermatologists really encourage consistent use to prevent 'retinization.' Retinization is the period of time in which your skin needs to adjust to retinoids, which usually lasts 4 weeks. When you stop using retinoids for more than that time period, you'd have to start all over, and your skin would have to re-adjust to the product.
Dear Brightly FAQ, on why auto-refill is mandatory
There is something real underneath this. Skin does adapt to retinoids over roughly the first month, and a long break does mean re-adapting. But 'you'd have to start all over' is a stronger claim than the evidence carries, and it is doing commercial work: it converts a billing policy into a clinical necessity.
A refill is a three-month supply. Refills ship 'every 3 or 4 months,' and the customer chooses. Anyone on the four-month cycle therefore runs out for about a month — the precise gap the retinisation argument says forces you to start over. A company that genuinely believed continuity was clinically essential would not offer a shipping interval longer than its own supply. Either the four-month option is a mistake, or the argument for mandatory billing is not really about retinisation.
This register has made the same finding in different clothes at R-01, R-05 and elsewhere: the reason given for continuous billing is usually a real pharmacological fact stretched one notch past what it supports. The fix is not to abandon subscriptions — for a genuinely long-term treatment they are sensible — it is to offer a one-off purchase alongside and let the clinical argument stand on its own.
The missing bottle
A two-month supply for $66 and a three-month supply for $99 are both $33 a month, which is a fair price. Neither tells you how much product you receive.
Without a volume, the supply claim cannot be checked, cost per application cannot be computed, and there is no way to tell whether a bottle that runs out early means you are over-applying or under-supplied. This is now the tenth product in the register where the container size is the missing number, and it remains the cheapest disclosure any of these companies could make.
If you are considering it
- Ask for your assigned strength in writing, and check it again at every refill — the range spans nearly sixfold.
- If you are given 0.015%, ask what the plan is for stepping up and when.
- Ask what the niacinamide concentration is. It is a fair question and the answer should be easy.
- Ask for the bottle volume, so you can check the two- and three-month supply claims yourself.
- Choose the three-month shipping interval, not the four-month one, if you accept the company's own continuity argument.
- Buy sunscreen — their own zinc oxide 10% product publishes its full ingredient list, which is a point in its favour.
- If you already use 0.05% tretinoin comfortably, this is unlikely to be an upgrade.
- Give it three months before judging, as the FAQ itself says.
Where we stand
At 61 this sits in the middle of the register: better formulated and more openly documented than most compounders, undermined by three omissions that are all easy to fix and one argument that does not hold together.
The company clearly knows how to publish — the base list is more detailed than several pharmaceutical excipient sections we have quoted. Publish the niacinamide concentration and the bottle volume, offer a one-off purchase, and drop the four-month shipping option or drop the retinisation justification. That is a short list, and it would move this several points.

Who this is for
- Someone starting a retinoid for the first time who wants a low rung and a vehicle designed to be forgiving.
- Someone who reacts to preservatives, since an anhydrous base requires none.
- Someone who will ask for their assigned strength in writing and track it across refills.
- Someone comfortable with a subscription who values clinician access at a flat $33 a month.
- You want to know exactly what strength you are buying before you buy it.
- You are pregnant, trying to conceive or breastfeeding.
- You want a one-off purchase — there is no non-subscription option.
- You need to compute cost per application, which no published figure allows.
- You have already used tretinoin successfully at 0.05% or above, in which case a compounded range starting at 0.015% is a step sideways at best.
