content helps to increase moisture and elasticity of skin.


Preliminary results of in vivo test of Osmocean PSK Protocol The clinical efficacy of Osmocean PSK bioactive was tested in vivo with a double-blind study. The studies were conducted with 40 volunteers aged between 35 and 75 years old, most of who had clear signs of skin ageing. A total of 20 volunteers applied the active ingredient at 3% and 20 volunteers applied placebo cream on the face, twice daily for 28 days. Moisture and elasticity were measured


on Day 0 and Day 28 by corneometer and cutometer, respectively, using a Microcaya multi-dermoscope. Additionally, eye contour wrinkles and facial expression lines were measured using ImageJ software.


Results Osmocean PSK has a moisturising effect improving firmness and uniformity complexion of the skin and better well-ageing effect. As Figure 5 shows, moisture level was increased by 12.7% using Osmocean PSK meanwhile it was reduced by -2% in placebo treatment. Elasticity was increased by 16% in volunteers


using Osmocean PSK and reduced by -1.9% in volunteers using placebo cream. These results evidence an improvement in a lifting effect probably due to organic osmolytes content of Osmocean PSK.
