Moisturizing
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:
hyaluronic acid, 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: dimethicone, butylene glycol dicaprylate/dicaprate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol, urea
Helps attract water to the upper layer of the skin and can help improve skin barrier function
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
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
Naturally 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
Helps soften the upper layer of the skin
Helps preserve products and creates a nice product texture
Anti-aging
What does the product description say?
C-ESTA Face Serum is a powerful antioxidant cocktail, featuring a lipid-soluble form of Vitamin C, DMAE, and hyaluronic acid to help reduce the appearance of fine lines and wrinkles and uneven skin texture while simultaneously protecting the skin from free radicals caused by UV exposure and environmental stressors.

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 - hyaluronic acid - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.
