What the product description says
“Moisturising Fluid 0.5% Hyaluronic Acid”
From product name

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: glycerin, sodium hyaluronate.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: butyrospermum parkii butter, caprylic/capric triglyceride.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol, urea

UreaHero· HumectantEffect: HighNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~1.4–2.1%

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - butyrospermum parkii butter - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

Product summary

"Altruist - Moisturising Fluid 0.5% Hyaluronic Acid" has a good moisturizing formula. 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 (panthenol, urea, glycerin, sodium hyaluronate and caprylyl 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). Cetyl dimethicone, butyrospermum parkii butter, caprylic/capric triglyceride, dimethicone and cetearyl alcohol 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

  • An effective concentration of Panthenol (pro-vitamin B5) - about 0.50% - 1.20%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: titanium dioxide

Irritation risk
