Pros
It has a high vitamin C content and is non-irritating in proportion to the content.
Cons
There are no regrettable points. It is slightly sticky, but that is the characteristic of high-vitamin content products, so I will accept it.

Pros
The irritation is not too strong compared to the concentration (similar to other products) The watery formulation makes it easy to use in combination with other skincare products The brightening effect is not dramatic or slow, but effective Affordable price relative to the concentration
Cons
Extremely fast discoloration and browning🥲 This product discolors much faster than other products, so it's necessary to refrigerate it for use. I've used various vitamin C products with concentrations ranging from 10% to 23%, but this is the first one that discolors so quickly. It turned bright yellow so fast that I just threw away the remaining product. Once refrigerated, the product needs to be kept refrigerated until the end of use, so I usually store and use it in a cool, shaded area, but this product definitely needs to be refrigerated.
Tip
Refrigerate and use the product

Pros
I was able to apply it only to the troubled areas without any irritation, and I noticed significant improvements in brightening and skin texture. Even my acquaintances commented that my skin tone looked more even. The formula was less oily compared to other vitamin C products I had used before, which was great for my oily skin type. However, since this is a high-concentration pure vitamin C (ascorbic acid) product, those with sensitive skin should exercise caution.
Cons
The product does have a distinct scent, which is common for vitamin C products. But it's not overwhelming.

Pros
I was using a vitamin serum from another company, but I decided to try the one from Izntree. It's really not irritating at all, and the vitamin C content is high, which I like.
Cons
The formula is almost watery, so you have to absorb it quickly. The effects also felt a bit less pronounced compared to other products.

I was worried it might be too stimulating, but it was fine as I gradually increased the amount.

Pros
In the summer, I try different vitamin C creams and tone-up products to avoid sunburn. This product has a unique water-based formula that applies lightly. It has a subtle but noticeable effect, so I've been using it consistently! After trying Ezentre, I found it to be so gentle that I've been exploring more of their products. I'm leaving this review in hopes that even better products from them will be released!
Cons
The dropper allows for easy dosage control, so there are no downsides!
Tip
I apply this as the last step in my skincare routine, and then I spritz on a facial mist to help it absorb. Absorb away~~~~~
