We're working on rolling out prepaid duties for more countries soon.
I bought this to improve rough skin. I apply it right after washing my face, and it absorbs quickly! I used to have constant acne, but since using this, it's calmed down considerably. The power of the concentrate is amazing. I'll continue using it.
I purchased this to treat pigmentation from burns. I was looking for a vitamin C derivative containing magnesium ascorbyl phosphate, so I'm glad I found it here. The liquid is smooth, but it feels a little jiggly. It's light and doesn't irritate. I've only just started using it, so I'm not sure how effective it is, but I'll continue using it until the pigmentation improves.
I bought this because my acne scars were not going away. After applying toner, I applied it over my entire face and to the areas of concern, and the next morning, I was surprised to see that my skin was one tone lighter! I use it during the day as well, and it seems to close my pores and make my skin less shiny than usual. I previously used Obagi serum, but I didn't feel any effect, and I was worried that vitamin-based serums would sting, but this product doesn't sting at all and seems to suit me better than Obagi. I've never felt such an effect from a skincare product, so I wish I had bought it sooner! I don't know about acne scars, but I'll keep trying it. I'd like to try their other products as well♪
I bought this product from Suzykirei and this is my fourth purchase! I only use it at night, either directly on the dark spots or by mixing it with my lotion. It's like a protective charm to prevent dark spots from getting darker, and I think it also brightens my skin tone!
It's great for dealing with dirty, enlarged pores and sebum. I bought it thinking it might also be effective for acne scars. This is a review after using up the whole bottle. ●The feeling of use was not strong and didn't sting. It's smooth and you can spread a small amount all over your face. ●Effects: First of all, my oil production during the day has become less. My foundation used to always smudge, but that's improved a lot. I'm not sure how effective it is on acne scars yet, but it did help new pimples heal quickly. I'd like to try other products, but I'd like to keep one on hand for acne!
