Pros
It has good absorbency, whitening effects, and good cost-effectiveness, so I think it's a good introduction to vitamin C serum like me.
Cons
It may sting and cause irritation, so adjusting the amount to suit your own skin is necessary.
Tip
It is sensitive to sunlight, so it's better to apply it only in the evening when it's dark, not in the morning. For those who are sensitive when using it with retinol-based products, it's good to use them alternately every other day or more.

Pros
I was looking for a high-concentration vitamin C serum and Izntree's product seemed to have good ingredients, so I decided to purchase it. It has good absorption and a nice finish, so I think I'll buy it again.
Cons
There is nothing at all. I think the price is reasonable considering the concentration.

Pros
As summer passes, freckles and blemishes appear, so this high-concentration pure vitamin C ampoule is a good choice. The packaging and composition well reflect the vulnerability of vitamin C to heat and air, which I'm satisfied with. The application also feels smooth and absorbs well, and the ingredients are well-composed with effective components.
Cons
Rather than expecting extremely dramatic effects, I'm applying it consistently as a maintenance measure.
Tip
If you apply it in the morning, using it together with a sunscreen is stable. For those new to high-concentration pure vitamin C, around 10-15% may be more comfortable.

Pros
My Own Money, My Own Review ★ I first purchased this vitamin C serum to see if it could help with my freckles and dark spots. After looking around, I decided to go with the Izandtree vitamin C serum as it was more affordable than other brands. Although there were no reviews, I decided to give it a try and used it for 6 days. ♣️ The watery formula comes with a dropper for hygienic application ♣️ It absorbs well and doesn't feel sticky ♣️ My skin looks radiant and glowing Right away, my skin looked brighter and more luminous, even with the freckles and dark spots. The absorption is good, and the watery texture doesn't leave a tacky feeling.
Cons
♣️ There is some irritation ♣️ Minimal effect on freckles and dark spots Like most vitamin C serums, there was some stinging at first, but it got better as my skin adjusted. However, it didn't cause any breakouts. The serum doesn't seem to have done much for my freckles and dark spots.
Tip
I make sure to apply sunscreen diligently! And I also use a retinol ampoule together with this serum.
