I came across the Zinc C Serum from my sister. I used this for a week and i could see such a big difference! I have very problematic skin. I have oily acne-prone skin with eczema patches on my face and this serum smoothed my skin. I can feel and see the difference in the texture and tone. Another big reason I love this product is that it is vegan! I love knowing that what I am putting on my skin is good and does not contain parabens, sulfates or animal by-products, etc. For most of my life I have struggled with my skin and in turn that has really affected my self-esteem and self-confidence. To me, you really can't put a price on that. I can't wait to try the rest of this 100% vegan line! Everything from skin, hair, body and even products for tattoos! It really is all about wellness in these products. I highly recommend this line, especially to those with sensitive and problematic skin!
