Great product, skin glows

I have used other Serum Vitamin C brands, when I first put this in a little goes a long way. My skin felt refreshed and hydrated. I’ve noticed my dark spots are somewhat lighter. My granddaughters remarked on how my skin glows. Truly a great and worthwhile product that definitely won’t break the bank. l

This has been one of my favourite Vitamin C serums. It has no fragrance which I enjoy and if you ease into it and use it in the correct skincare step order, over time it really does brighten and help with uneven skin tone I have found.
