Product summary

Judging from the ingredient list, "Ráya - COLLAGEN-ELASTIN CREAM RAYA SPA" works well for improving skin hydration This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Panthenol, alanine, aspartic acid, fructose and glutamic acid in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Palmitoyl tetrapeptide-7, carthamus tinctorius seed oil, glycosaminoglycans, triticum vulgare germ oil and squalane 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

  • this moisturizer includes a form of Retinoids (vitamin A) - retinyl palmitate 0.20% - 0.75%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • We like that this moisturizer contains peptides (palmitoyl tetrapeptide-7 0.40% - 1.00% and palmitoyl oligopeptide 0.45% - 1.10%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, 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 product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: allantoin
