Could this suit my routine?
Consider it as a serum step, not as a replacement for a moisturizer. The “100” in the name is not a statement that the serum is 100% PDRN.

Hyaluronic Acid / Sodium Hyaluronate
Hyaluronic acid
A water-binding ingredient used in moisturizers; sodium hyaluronate is a related salt form.
Research and what to check
A four-week trial on the legs of 36 older adults found higher hydration with a low-molecular-weight HA lotion than a high-molecular-weight lotion or the base. Water loss and symptom scores did not differ significantly.
