I'm reviewing a Vitamin C serum that I bought with my own money~

 

hello~

 

I have oily skin and am concerned about pigmentation and whitening, so I am using a Vitamin C serum.

 

I am going to review a product I bought with my own money that I am currently using well after finishing half a bottle.

 

Product Name - COSRX The Vitamin C 13 Serum

 

-

 

1. User Experience: I purchased the intermediate version, and I liked that it didn't sting or cause any side effects as much as I expected. (For beginners, I use the 15ml vitamin derivative serum.)

2. Texture: It has a runny texture with almost no viscosity, so I liked that it absorbed quickly. It had a slightly sour scent.

3. Effects: I liked that my hyperpigmentation improved faster because I applied sunscreen after using the serum every morning, and used a BHA cleanser and AHA toner in the evening to induce exfoliation.

 

4. Areas for improvement: There was a slight itching sensation at first. I think it was worse because I used a product containing BHA in the evening.
If your skin has become sensitive, I think it would be best to use a soothing base and allow some time for recovery before trying again.

 

5. Recommended Usage: Pure Vitamin C oxidizes quickly, so it is best to consume it within 1 to 2 months. Once I finish this without any issues, I plan to purchase the 23% concentration next time.
