This set is ideal for a short, one-week long treatment since we got here seven ampoules in total. I'm a fan of the opening of this product. I think it's a good set if you plan to go on holidays and not take all your serums with you. The composition is bit weak, you can find better vit C ampoules on market. Still, if your skin is sensitive to high Vitamin C, then it might be a good choice for you, since for me, as a person after retinoid treatment, my skin is ultra-sensitive to ingredients and even thinking about Vitamin C is painful for me sometimes, but with this serum - it works fine.
To be honest, 7-days is not enough to see a real change. Brand used here pigment and scent ingredients, because of pigment you never know if this product oxidized or not
