But to check which of these will turn out best for your skincare, I checked a few of the most popular products. 

Then ranked it based on the following criteria and finally came up with the best Korean vitamin C serum. 


A vital component of vitamin C is Magnesium Ascorbyl Phosphate that keeps the moisture inside the epidermal layer. So, one of the works of the serum is to keep your skin from dehydration. 

Promoting Collagen Production

A typical vitamin C serum will help you slow your ageing process- the reason being it helps in enhancing the production of collagen. 

In addition, the components of the serum help activate skin cells by increasing the flow of blood to the upper layers. 

Fading Hyperpigmentation

It is dermatologically tested and proven that a concentration of vitamin C helps aid your hyperpigmentation. So, as a result, it enhances your skin, making it stay youthful and glow. 

Healing Power

According to me, it is the most crucial criteria for a vitamin C serum to be checked before adding to the skincare regime. 

Vitamin C is long known for its healing factor of scars and even damaged skin. Additionally, it helps in healing the skin sagging issues along with pigmentations.
