How long should you wait between Retinol and Lactic Acid?
Does It Mix engine · wait time
Waiting a few minutes isn't the fix here: use Retinol and Lactic Acid in different routines (morning vs night) or on different nights.
The routine
- Night A: Retinol. Night B: Lactic Acid. Or use Lactic Acid in the morning and Retinol at night if your skin tolerates it.
- Start slowly (2-3 nights a week each) and moisturize.
- Daily sunscreen is essential with both.

FAQ
Does waiting 20 or 30 minutes between products help?
We haven't found good evidence that a set wait of many minutes changes how most skincare works. The practical reason to pause is letting each layer absorb so the next one doesn't pill or sting.
