This is definitely the best of their products. As soon as it starts drying after I've applied I feel my skin begin to tighten up. Since I started using these products my dry patches have disappeared and my oily areas dont get shiny. I do all 5 steps in my routine and I feel like i'm truly treating my skin. I wont be using any other product any time soon.

I have very sensitive skin and this product has made a big difference. Even after the first two days, you could notice an improvement. Some of my friends have asked me what I am using that my skin looks so different. I am looking forward to try their other products.

The Vitamin C Serum is working well I`m noticing that my acne scars are fading and are also I`m not breaking out as much. I love the way it makes my skin feel so smooth and soft going on and as well as after. Also, the customer service is amazing Erica answered any questions that I had.

I haven't picked up on a scent and I'm unsure if it's good for sensitive skin since mine isn't. I have dry skin and has always been fairly acne free. I bought this since apparently I'm getting older and I also have some dark spots, which do appear lighter. It dries my skin out so I just apply a moisturizer afterwards.

Works. That's all I can say. Do not hesitate to purchase. I have combo skin, and I am of mixed ethnicities. I'm in my early 30s. I HAD uneven skin tone, some discoloration and old acne scars. This has and is continuing to clear those up. This company's customer service is absolutely standout amazing. They care about you as a customer and how their products are working for you. I literally received follow up emails from their cofounder checking in to see how the serum was working for me. Customer for life! ?

Definitely would not sub this for a moisturizer if you have dry skin but this is amazing if you have combination or oily acne prone skin. I use this at night and in the morning under my makeup and it really has cleared up my skin and made my super oily skin less oily

I travel internationally a lot (6-8 countries per year) and the long flights and constantly changing water PH/chemicals are really hard on my skin. I am a 29-year-old woman, mixed race, and I have combination skin that can either be incredibly dry or very oily depending on the local weather/air/water. My skin is not particularly prone to acne, but can have red patches, dry patches, oily patches, and one beautiful patch all at once. I frequently fly from the U.S. to India and the extreme dry on the plane followed up with the extreme humidity and pollution in India are my skin`s worst nightmare. I used half a bottle of this Vitamin C serum in December 'Äì after two weeks in South America, and a week in the U.S., I flew to India for two weeks. The only other product I used on my face were generic face cleansing wipes and a bit of vitamin E oil (which I`ve used for years as a moisturizer). I applied the Vitamin C serum morning and night. Despite pollution, exhaustion, jet lag, and humidity, my skin looked incredibly bright and continued to do so after my return trek home to dry winter air. This is my 10th repeat trip to/from that part of India and my skin has NEVER handled it this well. I`ve tried so many different kinds of moisturizers and oils that never helped much. I will definitely be using this serum in the future 'Äì just ordered my second bottle so I don`t run out during another upcoming trip. Highly recommend.

I`m loving it so much. I started using this product with at home microneedling. My skin looks hydrarated and full. I was told to use the c serum with this process. I have heard alot of others rave about your product. I am pleased. I plan to keep purchasing in the future.

I decided to try this serum because of the positive reviews and affordable price. However, after using it for over a month, I`m struggling to understand what all the fuss is about. There`s no noticeable difference in my skin and the product seems cheap compared to other serums I`ve used. I`d recommend buying the 1 fl oz. container if you feel compelled to try it out.

I have been using vitamin C serum for about a month. It goes on smoothly and absorbs quickly. I apply it once a day under my moisturizer in the morning. (A little goes a long way) my skin definitely looks brighter, feels softer and a little smoother. Very happy with results. Fast delivery too!
