My impressions after using Blue Green: I won this product as a gift! I'm incredibly happy to receive it, but I don't want to lie just because it's a gift, so I'll give my honest opinion. *Honestly, it was neither good nor bad. Generally (in my opinion), blue is used to enhance clarity and tone, while green is used to reduce redness, but I couldn't really see the effects of either. I like that it's suitable for sensitive skin and that it's incredibly moisturizing and spreads easily, but perhaps it's too moisturizing, so it doesn't feel like it provides much coverage. It might be suitable for those who are only slightly concerned about natural redness, but for those who are particularly concerned about redness, it's not enough. I found it a little lacking for me, so I mix it with another primer and use it. The moisturizing effect acts like a glow, which is great!
