What’s the Difference Between Retinol and Retin-A?
Both Retinol and Retin-A are forms of Vitamin A, but they act differently:
| Feature | Retinol | Retin-A (Tretinoin) |
|---|---|---|
| Strength | Over-the-counter | Prescription only |
| Speed | Slower results | Faster results |
| Irritation | Mild | Can cause redness or peeling |
| Availability | Available in creams & serums | Only via prescription |

Do Doctors Still Prescribe Retin-A?
Yes, dermatologists still prescribe Retin-A (tretinoin) — especially for acne and aging concerns.
However, because it’s stronger than over-the-counter retinol, it’s usually prescribed in low concentrations.
If you want something milder to start with, try an OTC retinol serum like this one from Amazon:
CeraVe Resurfacing Retinol Serum
Can You Use Retin-A Forever?
Not exactly.
While tretinoin (Retin-A) can be used long-term, dermatologists often recommend taking short breaks if your skin becomes dry or irritated.
Consistency matters, but overuse can damage your moisture barrier.
Pro Tip: Alternate nights between Retin-A and a hydrating moisturizer.
Does Amazon Sell Retin-A?
No — Retin-A requires a prescription, so you won’t find the real product on Amazon.
But you can find Retinol alternatives that are gentler and still effective.
Recommended Product:
RoC Retinol Correxion Deep Wrinkle Night Cream
Why Is Retin-A Discontinued?
It’s not discontinued — but some brand versions of Retin-A were rebranded or reformulated.
You might see “Tretinoin Cream” or “Refissa” instead of the old Retin-A label.

Can Retinol Cause Neck Rash?
Yes — applying Retinol too close to thin areas like the neck can cause irritation or rashes.
That’s because the skin there is more sensitive.
Always moisturize before and after using retinol, and start with a low concentration (0.3%).
