Product summary

Based on the ingredients included, "Bi-Oil - Dry Skins Gel" works well for moisturizing the skin. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Humectants in this product (urea, glycerin, sodium hyaluronate, sodium lactate and sodium pca) 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). Paraffinum liquidum, glycine soja oil, isopropyl myristate, linolenic acid and butyrospermum parkii butter 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 product contains acids (gluconolactone 0.50% - 1.20% and lactic acid 0.40% - 0.90%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). PHAs (gluconolactone) especially are great for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
  • This moisturizer includes a form of Retinoids (vitamin A) - retinyl palmitate 0.15% - 0.70%, 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.
  • Another helpful ingredient in this moisturizer is Linoleic Acid. It is one of the fatty acids naturally present in skin. It is part of the skin barrier. Preliminary research shows that it might be able to reduce clogged pores.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: vitamin e, niacinamide and lactic acid
