The useful disclosure is that different formulas exist and may change during care. That is a reason to ask for the current prescription and transition plan, not to treat every ingredient on the page as one continuous combination.

The public offer is now $110 for an 18 g, nominal 60-day supply. This updated review removes the old price and a fixed cycling schedule that the current page does not establish for every patient.

## Actives, as published

| Active | Concentration | Role | Benchmark | Assessment | Flagged |
| --- | --- | --- | --- | --- | --- |
| Hydroquinone or non-hydroquinone combination | Individual prescription | Hyperpigmentation treatment | Diagnosis and formulation-specific evidence | Potential ingredients include azelaic acid, kojic acid, green tea extract, resveratrol and hydrocortisone. Their listing is not a guarantee that each appears together. | no |

## Scoring

| Criterion | Weight | Score | Note |
| --- | --- | --- | --- |
| EVIDENCE FOR THE ACTIVE | 30% | not scorable | Ingredient background is discussed separately. No performance score is assigned to an untested service or to a prescription that varies by patient. |
| FORMULATION INTEGRITY | 20% | not scorable | The exact dispensed preparation, manufacturer or patient-specific base was not inspected. |
| DISCLOSURE | 15% | 75/100 | Publishes price, mass and the existence of different formulas; individual concentrations and transition dates still require the treatment plan. |
| TOLERANCE IN USE | 15% | not scorable | No patient panel or personal treatment course. Cannot infer tolerability from ingredient names or testimonials. |
| TEXTURE & WEAR | 10% | not scorable | No product-in-hand testing. |
| COST PER APPLICATION | 10% | not scorable | Published fees are compared in the text. Actual dispensed quantity, application amount and usable duration are needed for this criterion. |

_A criterion that cannot be assessed from published information is not guessed at. Its weight is removed from the denominator, and the coverage figure above says how much of the model survived._

## Strengths

- Separates hydroquinone and non-hydroquinone possibilities.
- States mass and nominal supply duration.

## Weaknesses

- No single course schedule applies to every reader.
- A higher hydroquinone strength claim does not establish a proportionally better result.

## Suits

- Someone with a diagnosed pigment concern who can follow a clinician-directed course and review plan.

## Avoid if

- You expect to continue a hydroquinone or steroid-containing formula indefinitely without reassessment.
- You are pregnant and considering hydroquinone; discuss an alternative with your clinician.

## The full assessment

### The updated price and formula record

Agency lists Dark Spot Rx at $110 for 18 g, described as a 60-day supply. Its menu includes hydroquinone and non-hydroquinone preparations and several possible adjuncts. The FAQ describes provider-directed transitions to a non-hydroquinone formula; it does not establish one universal calendar. Confirm the ingredients and dates in your own plan.

### A course has more detail than a renewal date

Write down the concern being treated, the planned application area, review date and what would lead to a change. If the proposed preparation contains a corticosteroid, ask about its role and duration. A subscription interface can organize delivery, but its next billing date does not independently determine how long a drug belongs in the treatment plan.

**COMPARE PIGMENT TREATMENT RECORDS**

- [R-35 Galderma Tri-Luma](/reviews/tri-luma-cream-review) — RECOMMENDED 85/100 — A defined approved combination with a specific melasma indication.
- [R-66 Strut Health Melasma Formula](/reviews/strut-melasma-formula-review) — CAUTION 45/100 — Another compound whose course needs explicit planning.
- [L-11 Before a compounded melasma prescription: five questions to ask](/ledger/compounded-melasma-questions) — Questions about diagnosis, ingredients, duration and follow-up.

### Do not make strength do the work of a trial

A concentration can be higher without demonstrating proportionally better clearing or acceptable tolerance for a particular person. Read product-page comparisons as claims to investigate. The relevant evidence must match the diagnosis and regimen, and evidence for a different finished product does not automatically validate this compound.

### What belongs alongside the prescription

AAD's melasma guidance places diagnosis and sun protection within treatment. Ask your clinician how those fit your plan, including what to do if pigment worsens or irritation appears. A change in discoloration is a reason to reassess the situation; it should not automatically trigger buying a stronger formula.

### Comparison limits

We did not receive a dispensed container or observe a treatment course. The updated score assesses the public specification only. Compare the full period of care, including transitions, before treating a lower price per shipment as a lower cost for the whole plan.

## Where to buy

| Retailer | Price | Link | Note | Commission-bearing |
