Product Summary
"BIOTHERM - BIOMAINS HAND CREAM" is a well-rounded moisturizing product. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Panthenol, glycerin and caprylyl glycol 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). Dimethicone, dimethiconol, cetearyl alcohol, glyceryl linolenate and caprylyl glycol 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 0.55% - 1.30%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.

Moisturizing
What does the product description say?
BIOMAINS HAND CREAM
Source: 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, caprylyl glycol.
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: dimethicone, dimethiconol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
Red algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency
Helps attract water to the upper layer of the skin and can help improve skin barrier function
A silicone that makes products more spreadable and keeps skin smooth. Helps to add gloss to skin and may visually fill in fine lines/wrinkles for short time
