I really love this Vitamin C serum! I think it’s the best one out there, but it’s soooo expensive :( I do wish all of the products I ordered from the Skinstore came to me with expiration dates. Some products do, but many others like this Vitamin C serum doesn’t, and it was already oxidized when it arrived to me. Anyway, I love this brand specifically for the CE Ferulic vitamin C! IF it’s in good condition and not old or expired, it can really make your skin glow! It layers so well with other skincare products in the mornings before applying makeup! AM routine: So I wash my face, apply vitamin C, then apply another serum, next I apply my lotion (not a cream- I use a cream in the pm), and lastly my spf-all before makeup. This vitamin C really works well with other skincare and makeup! No pilling. Excellent brand and an excellent Vitamin C serum!

I have written a review of this C E Ferulic Serum before. I have been using it for at least 8 years. It absorbs well into my skin. It doesn't have a pleasant smell, but it goes away quickly. I am really writing this review, because I want people to know that positive reviews can be misleading. I genetically have bad skin: used to have acne, have large pores, discoloration, uneven skin tone, wrinkles, etc. I am over 50, and some of the sun spots and wrinkles appeared since I have been using the serum and sunscreen every single day. So, just like any other product, this one is not a miracle either. However, I am hoping that it did something to somewhat preserve my skin, so I keep using it. I will never know what my skin would be like without it, but C serums are recommended based on today's beliefs of dermatology, so it helps me at least psychologically.

I finally gave in and bought this product at the urging of my facialist. I complained of dark spots and general aging of my skin. I am 67. I am on my third bottle now. Will always use this. My skin is clearer and brighter, no spots. That said, I also use the B5 gel in the mornings with this. At night I use the Resveratrol serum and HA Intensifier. I use the glycolic cleanser - amazing for exfoliation. My pores are clean, skin is smooth. Totally sold on this product line. My skin is smooth, bright, toned, spotless.

This was my 3rd time purchasing this product. I’ve purchased from other vendors and haven’t had issues. This one was already a dark yellow upon opening it and with in a month was light orange. Kind of disappointing for the price of the product.

I like SkinCeuticals products, but will no longer be using this product. I used it for a couple of weeks and I really just can't deal with the smell. And I keep smelling it all day. I wash my hands thoroughly and still smell it and then the smell is still on my face. I have no doubt it works well, but it's just not for me.

This is the CTO beat, I cannot even imagine a day without my CE Ferulic! I start each morning with it, it absorbs well and gives me a fresh smooth face to begin the day!

This caused an extremely bad reaction on my skin! To the point I did not want to leave my house. My face turned beet red, dry, painful and inflamed giant acne. My skin texture was destroyed and honestly my skin has never looked worse. This probably works for most people but wow it did not for me. I do have sensitive skin but I saw tons of reviews saying it was great even for people with sensitive skin. I researched and at first thought it was purging. But by a week in and my face was so painful and insanely red I decided there’s no way that was what was happening. Be careful! Don’t use if you regularly exfoliate as I read that could have made it even worse.

I started using C and E Ferulic six years ago as recommended by my plastic surgeon and have used it since that time. I get a lot of compliments on my skin and I am 68 years old. The price is tough because it’s very expensive but I am rarely without it. I have tried other products in between and do not like them as much. I use it on my face and neck in the morning right after cleaning. I do use retinol’s once or twice a week so who really knows whether the C and E is making the difference but I’m going to stick with the routine. My skin tends to be very dry with some freckles and sun damage but after using this product, my skin is more even and looks sort of dewy fresh. Worth a try.

I've used these Vitamin C drops for about 5 years. I always bought them at my local spa but found them on sale here, plus a free sample, resulting in cost-savings. I won't buy at the spa again. As for the drops, who really knows if they work, but I've been told they are one of the best thing you can do for your skin, but you need high grade products. This brand is highly rated as one of the best.

This serum is my skincare splurge. Since the formula has been tested for stability and efficacy, it’s the only one I use now. I’ve had to prioritize my skincare spending, but this is the one I buy for Vitamin C because it works. I used to use a couple other brands, but I’m not sure they worked like this one.
