Efficacy of a Morinda citrifolia based skin care regimen.
West BJ, Sabin RA.

A six-week clinical trial of a noni based skin care regimen was conducted with 49 women, ages 38 to 55 years. Daily application of three product formulations to the face and neck resulted in significant reductions in lateral canthal fine lines and wrinkles (crow’s feet). In this study, skin elasticity and firmness also improved.  No evidence of skin irritation was present in any participant at any time during the trial.
