I love I'm Your Hero and when I bought two bottles to stock up on, I happened to find a Megapo gift here, so I was lucky enough to try it out (a bit rude, lol). It's a vitamin C derivative, but this is my first time using it as a primer, and I'm sensitive, so I was a bit hesitant to use it. It's completely non-irritating! It doesn't have the sticky feeling that vitamin C typically has, but I'm not sure if it's really a primer. It didn't absorb well, like when you apply a toner without a primer serum. It's not bad, but I wonder if it would be better to use a primer serum first. lol After that, I went with Dr. Ci:Labo Lotion → COSRX Niacinamide → anua PDRN → Goodal Serum → Tuveil Emulsion. I usually use SUQQU primers, which have incredible penetration and suit my skin, so I'm not sure if I should switch. However, since I have 30ml, I'll consider using it in my morning skincare routine and see if it's good. ^ ^ I really recommend it for its non-sticky and non-irritating properties, so it's definitely worth a try.
I feel good when I use other companies' vitamin C serums, so I bought this one to try out their products. Even though it's supposed to be applied immediately after washing your face, I often forget and put on lotion instead, so when that happens I don't apply it again, but I use 3-4 drops almost every morning and night and it lasted me about a month. Just like the other companies, it gives my skin a clearer, brighter look. The ingredients are effective on pores, but the effect on the pores isn't that noticeable. I'm always bothered by the smell of vitamin C serums, but this one is almost odorless, which is a relief. I think I might try the one I was using again and if it doesn't make much difference, I'll buy this one again as it's easier to use and doesn't have a bad smell.
I tried it as a magazine supplement and loved it so much that I bought the actual product!!! I was looking for a Vitamin C serum with a smooth texture, and I was attracted to this one because it wouldn't interfere with my next skincare routine! The texture is easy to add to your skin, and it somehow brightens my skin and closes my pores!
I received this as a magazine supplement. First of all, it's very pleasant to use. It doesn't irritate my skin, and the scent isn't particularly bothersome. However, I only used 10ml this time, so I don't think I'll see any effect until I continue using it. Also, the price is a bit of a problem, so I'll consider buying it again.
It was easy to use without any irritation, but I didn't notice any tone-up effect, so I won't be buying it again.
