Vitamin C Facial Serum with L-Ascorbic Acid 15% with Vitamin B5 .
Source: From product name
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals.

The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: arbutin.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

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:
arginine, 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: arginine, aloe barbadensis leaf extract.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
Helps attract water to the upper layer of the skin and can help improve skin barrier function
An amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin
