HA IMMERSE Serum was evaluated in an eight-week, open-label, multicentre clinical study involving 48 participants aged between 27 and 69 years. Forty-six participants completed the study.

Participants applied the serum twice daily and were assessed at weeks two, four and eight. The evaluation included instrumental hydration measurements, investigator assessments, participant questionnaires, clinical photography and a small biopsy subset.

The study reported statistically significant improvements in measured skin hydration at weeks four and eight compared with baseline and the preceding assessment.

Manufacturer-reported participant findings included:

98% agreed that their skin felt smoother immediately after application

91% agreed that the serum replenished moisture after four weeks

91% agreed that their skin’s overall appearance had improved after four weeks
