If your other vitamins c become oxidized really quickly I recommend you to buy this one because it wont. You have to find the right product to combine it, because it don't mixed really well with everything. I mix it with COSRX Snail 96 Mucin Power Essence, both work really good.
Заказала эту пудру чтобы добавлять в крема, пользовалась месяцев 5-6, и что-то не заметила особого еффекта. Буду использовать дальше, надежда умирает последней.
I have been using the Real Vita C Powder Lemon since it came out. I can definitely tell a difference in my skin. The little sun spots have faded significantly and my skin looks more radiant.
