"Shiseido - SFS LX Replenishing Treatment Oil" has a good moisturizing formula. 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 (sodium acetylated hyaluronate) 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, carthamus tinctorius seed oil, isopropyl myristate, oenothera biennis oil and caprylic/capric triglyceride 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.

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:
sodium acetylated 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:
caprylic/capric triglyceride, dimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: paraffinum liquidum
