Cool Mingeonnyeo - COSRX Vitamin 23 Serum

Product Review

 

 

COSRX Vitamin 23 Serum

 

It is also famous as a vitamin serum selected as Director Pi's Top of Top.
This is an item I had added to my shopping cart to buy once I finish the B00 that I am currently using to dissolve dark spots.

Stimulation :
With the serum I was using before, I felt a slight irritation only on the first day, and if I apply it after applying toner...
I adjusted well starting the next day, so I didn't feel any stinging sensation at all.
I applied it right after washing my face on the first day, and wow...it stings so much...
I was worried it might flip out from the stimulation... but it didn't.
It is fine if you apply it after toner or essence.
A great tip is to wait a while before applying it if you have exfoliated or have a wound.
It has been about a week since I started adjusting, and if I apply it immediately after washing my face, it works even on other days after exercising or being in the sun.
I felt a stinging sensation here and there.
I intentionally skipped my toner to see results, but it works fine if you apply it after your basic skincare routine.
I didn't feel any significant irritation or redness even after layering it twice.

 

Whitening effect:
Above all, the brightening of the complexion and the clearing of the tone felt after waking up the next day
I could feel it throughout, so I decided to write at length.

 

Skin texture:
I have a habit of sleeping on only one side, so I had bumps and some small bumps on my cheek, but after applying 23 every night

My skin texture has become smooth.

Texture: Since it is a runny, watery serum, it feels wasteful as it drips from the dropper.
You must control the amount and aim carefully so that it does not drip off the skin.

 

conclusion:
Among the vitamin serums I have used, I felt that this one showed decent results in the shortest amount of time.
Since I am in my 50s and my age spots are still going strong, I intend to write at length.
I believe that any irritating areas are perfectly fine as long as the individual adjusts them according to their skincare routine and condition.

You should skip this on days with wounds, peeling, exercise, or heavy exposure to UV rays.

I only apply it at night, and I do not apply it together with any skincare products containing peeling ingredients.

I am only using a very mild moisturizing cream along with it.
