The cheapest way to get tretinoin legally in the US is to use RedBox Rx, which offers a combined cost of approximately $85 for a 3-month supply (including a $25 online consultation and $20/month for the medication).
Key Cost-Breakdowns of Cheapest Options:
| Service | Consultation Fee | Monthly Medication Cost | Total for 3 Months | Why It's Cheap |
|---|---|---|---|---|
| RedBox Rx [6][9] | $25 | $20 | $85 | Lowest bundled price; transparent flat-rate medication. |
| GoodRx Gold + Telehealth [1] | $19 (with $10/month subscription) | ~$34/tube | ~$130/year ($108 for 3mo) | Requires subscribing to GoodRx Gold ($10/mo) but works for many pharmacies. |
| Amazon One Medical [2][8] | $29 | ~$20–$40 | ~$89–$109 | Fast virtual appointment; Prime members get same-day shipping. |
| Miiskin [4] | $59 (first visit) | ~$49/tube | ~$158 | Higher consult fee; includes customized formulas. |
Important Legality & Savings Notes:
- No Over-the-Counter Purchase: Tretinoin is not available over the counter (OTC) in the US; you must have a prescription from a healthcare provider [3][4][7].
- Use Generic: Always request the generic tretinoin instead of the brand name (Retin-A) for the lowest cost [1][3].
- Size Matters: A 45g tube is significantly cheaper per gram than smaller 20g tubes [1].
- Compare Pharmacies: If using a telehealth service that sends you a prescription (not RedBox Rx), use GoodRx to find the cheapest local pharmacy for that prescription [1][3].
Recommendation:
For the absolute lowest price with minimal hassle, sign up for RedBox Rx [6]. Their $25 consultation covers the medical review, and the medication is a flat $20/month with free shipping, making it the most budget-friendly fully online solution. If you already have a frequent telehealth provider or want to use a discount card at a local pharmacy, the GoodRx Gold + Telehealth bundle [1] is a strong alternative, though the subscription adds a small monthly cost.
