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.

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, cetearyl alcohol.

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.9–5.9%
Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~3.7–5.6%
Glyceryl stearate seKey activeEffect: MediumUsed to stabilize the product formulations and works as an emollient~2.5–3.7%
Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~2.1–3.1%
Collagen amino acidsKey activeEffect: HighHelp attract water to the upper layer of the skin, soften it and support the skin barrier function~0.15–0.55%

Effective ingredients missing or their concentration is too low.

Sodium ascorbyl phosphateEffect: Low, below effective doseA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.4–0.9%
