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: caprylic/capric triglyceride, heptyl undecylenate.
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Helps soften the upper layer of the skin, reduce water loss from the skin surface over time and create a nice product finish
Helps preserve products and creates a nice product texture
This product contains antioxidants (tocopheryl acetate). In theory, they could help neutralize free radicals in skin and lessen the damage it gets from the UV light (sun), but there is no evidence that these ingredients can have a noticeable effect in skin.
A more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.
An essential oil. Can be irritating. Can become an allergen with oxidation
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.
Featuring tetrahexyldecyl ascorbate (a low irritation form of vitamin C) combined with co-antioxidant vitamin E, the moisturizer helps to reduce the appearance of premature skin aging signs .
