Ana, I’m not a fan of these cheap Vitamin C serums, from either brand. Neither of them also contain ferric acid or vitamin E, which help boost the effectivess of Vitamin C.

Claudia, they’re very similar. They both give you just one or two actives per product, at a cheaper price. In the end, it all comes down to personal preference (texture, smell etc).

K, I couldn’t agree more. 🙂

Jeff, after you hit the 1% mark, ingredients can be listed in random order. So you can have more retinol than retinoate and list them in inverted order.

Andrew, I agree with you. I think there is a place in skincare for single ingredient products. For ex, if you’ve already got your skincare routine down to a T and want to add just ONE new ingredient, like an acid or retinol.

Otherwise, multitasking products are the way to go. When you do the math, you often realise that buying 6/7 one single ingredient products turns out to be more expensive!
