8/24/2023 Product change notice: Lotioncrafter has switched to the preservative-free version called Pepha®-Tight CB. No other specification changes were made, please refer to the Tech Data tab for more info.

Pepha®-Tight CB is a highly purified biotechnologically produced extract from the microalgae Nannochloropsis oculata combined with a well balanced fraction of polysaccharides. It functions as a skin tightener which provides immediate tightening to the skin. It has been shown to protect human fibroblasts from oxidative stress, simultaneously increasing the formation of collagen-l thereby promoting a long term tightening effect through the strengthening of the skin's connective tissue.

Pepha®-Tight CB can be used for all skin tightening applications including lifting products, masks, decollete treatments, gels and serums.

In comparative testing done by the manufacturer between Pepha®-Tight and Pepha®-Tight CB,  the removal of preservatives has shown neither a negative impact on all the tested formulations, nor on their stability. In system based on electrolyte sensitive thickeners, the new Pepha®-Tight CB has shown a lower decrease of the viscosity compared to Pepha®-Tight. The comparison of the color change at different pH's did not show any significant difference between the two products.

     INCI: Nannochloropsis Occulata Extract (and) Pullulan
