The best vitamin C on the market. Very gentle on my sensitive skin. I would definitely recommend.

I haven't observed any significant changes at this time. I will provide an update if there are any notable developments in the future.

I have been using Serious Skincare products for almost 30 years. Best skin care ever. I look much younger than my 63 years.

I love the C3 C Serum. It is perfect for my aging skin. I am 52 and have always had oily skin. Now I need more moisturizer due to my age. This serum is moisturizing without leaving an oily residue. It give my skin the what it needs to be balanced.

This product I use twice daily. First I use it on my silicone under eye patches. Leave in for about 30 minutes. Then use all over face and neck. I can definitely see a difference in my fine lines and wrinkles. Lines in my forehead are no longer deep. Crows feet are gone. It's amazing. I will be a forever user. LOVE IT!!! HIGHLY RECOMMEND!!!

The product is good, byt the price has gone up and it is NOW 1/2 the amount of product from what it use to be. I used it few years back for a couple of years. I can not afford it anymore.

I’ve been using this serum for years. I’m in my mid 40s and wanted to incorporate vitamin C into my routine. I’ve tried many different brands and I always come back to this one. I have sensitive skin and the ingredients are gentle. I would definitely recommend.

It works. I have used Serious Skin Care for decades. It was the first to come out with many of these treatments. Then the others followed. It is also much more affordable than other brands. Thank you Serious Skin Care

I use this to add a little moisture to the skin after using the glycolic serum and to boost brightness to the skin.

I have used for years as with the retinol renewal get I love both. The vitamin C gives your face a beautiful glow and clean look on your face. It also helps reduce any age spots on your skin. This product is a must have. Jennifers products are outstanding , she sold needed products before they became popular everywhere else. She even had the red, blue, and green light therapy before everyone else. Thank Jennifer.

Feels great going on. Haven't use but a week. Love the results

It's just okay. I'm an esthetician so I use top-notch, high-grade C products. This seems "less than" what I'm used to. Also, there's so little product in the container. I'm sure I'll use it all up in a few weeks. The peel pads are okay, but not what I remember when I used to buy from HSN: they seem much thinner. Overall, not great, not terrible.

I have used this for years and I love it. Best Vit C serum on the market

It’s light feeling, not a heavy cream feeling. It makes my skin glow. I’m 76, and most people think I look about 50ish.

Really like the product. Wish you would offer a bigger size. Would also be nice if you could offer seniors a discounted price. Been a customer for years and will remain one as long as the quality remains
