Can I Use Ha with Retinol?

In addition to being a terrific hydrator, Wechsler says, HA pairs well with other active skin-care ingredients (so you can layer it with retinol, for example, and use it daily).

Do you use retinol or hyaluronic acid first?

You should use hyaluronic acid after retinol. And to maximise the benefits, you should use retinol first and then wait at least 30 minutes before applying hyaluronic acid.

What should you not mix with hyaluronic acid?

Second, you should avoid anything with harsh ingredients like alcohol and fragrance or anything with a high acid concentration. “The majority of over-the-counter (OTC) cosmetic creams, lotions, and serums are water-based and contain less than 2% hyaluronic acid,” explains Frey.
