OPI Prospa Intensive Callus Smoothing Balm

"OPI - Prospa Intensive Callus Smoothing Balm" is a well-rounded moisturizing product. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Humectants in this product (panthenol, glycerin, hydroxyethyl urea, sodium lactate and butylene glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, glycine soja oil, isopropyl myristate and persea gratissima oil in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

• We like that this moisturizer contains peptides (palmitoyl tripeptide-1 0.25% - 0.45% and palmitoyl tetrapeptide-7 0.25% - 0.45%). There are many different kind of peptides and they are naturally present in our skin. They all are a combination of amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
• This formulation also uses an effective concentration of panthenol (pro-vitamin B5) - about 0.95% - 1.15%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
