Can I use alpha arbutin with retinol?
Yes. They work on the same problem from opposite ends and do not conflict. The care this pairing needs is the care retinol needs by itself.
Yes. Alpha arbutin reduces how much pigment new skin carries, and retinol speeds up how quickly pigmented skin is replaced. Use alpha arbutin daily and bring retinol in slowly, every second or third night to begin with.
Why they do not conflict
Alpha arbutin slows tyrosinase, the enzyme that makes melanin, so the skin being formed carries less pigment. Retinol increases the rate at which the outer layer is replaced, so existing pigmented cells leave sooner.
Those are two separate actions on the same mark. Neither depends on a pH the other disturbs, and alpha arbutin is gentle enough that it adds little to the irritation retinol can cause.
How to layer them
In one evening routine: cleanse, dry the skin, apply alpha arbutin, let it settle, apply retinol, then moisturise.
Split across the day: alpha arbutin in the morning under sunscreen, retinol at night. This is the simpler option when you are new to retinol.
Where the caution sits
Retinol is the ingredient that needs managing. Start every second or third night. Expect some dryness in the first weeks. If the skin gets tight or flaky, put a moisturiser on before the retinol, or drop back to fewer nights.
Alpha arbutin can continue daily through all of that.
Sunscreen
Retinol leaves skin more easily irritated by the sun, and sunlight is what drives pigment in the first place. Using this pairing for marks without daily sunscreen works against itself.
Who should check first
In pregnancy or while breastfeeding, take decisions about retinol and other actives with your doctor. If you are using a prescription retinoid, your prescriber's instructions come before anything on this page.

Related questions
Which goes first, alpha arbutin or retinol?
Alpha arbutin first, as it is usually the thinner product. Let it dry, apply retinol, then a moisturiser.
Can I use alpha arbutin in the morning and retinol at night?
Yes. That split is the easiest way to use both, and it keeps retinol away from daylight.
Can I use them together every night?
Alpha arbutin can be used every day. Retinol should be increased only as the skin tolerates it. Nightly retinol suits some people after a few months and never suits others.
