Well, I'm sad to say that I'm one of the few who did not have a good experience with this serum. I've given it three separate tries with no success. It completely dries out my skin to the point of flaking and leaves me with blemishes within 24 hours. The second time I tried using it for about three weeks to see if the blemish issue would calm down but it only got worse. Before using the serum I had maybe had four or five blemishes in my entire life. Yes, I've been that lucky. My skin just was not happy with this with this serum.

Truly excellent customer service, and extraordinary kindness, to boot. I inadvertently ruined the dropper on my vitamin C serum while opening the plastic packaging. Not only did they immediately agree to send me a replacement, they also sent me a very kind get-well note upon learning about my recent knee replacement surgeries. Still new to the product, but so far I could not be more satisfied.

I purchased this based on reviews, and I am pleasantly surprised to report the product is legit -- which I was not expecting based on the price. I have been using daily before bed after removing makeup, then applying vitamin E moisturizing cream. I do see a visible difference in my skin, particularly in the morning after washing my face.

This is one of the few products that actually works on my acne-prone skin. I`m 47, have had acne issues since...forever and this Vitamin C serum really helped reduce the appearance of my acne scars (red marks). This product along with Cosrx Bha Blackhead Power Liquid 100 Ml is all I use now to control my breakouts. Highly recommend it.

I love the serum! Nice fragrance and absorbs quickly into my skin; is making a big difference in moisture level and luminosity, and even my pores are looking smaller. My daughter was home to visit and used it, and now she loves it too. Thank you for creating such a good product. I just recently ordered 2 more bottles (because I don`t ever want to be without it), one for me and one for my daughter!

Product is top notch. I can actually feel the serum tighten the skin around my eyes. I have bought 3 different products now, and will continue to try others in the line. I highly recomend. Customer service was very helpful and quick to a few questions I had about application. I had as very happy with this buy.

I have had a chance to really test out the product and it has now become part of my everyday routine. I use it once daily. Preferably in the evening right after my shower when the pores are open. I just feel like it soaks in better lol. I really do enjoy the product.

I`ve only been using this product for a short time, but what I love best about this, as compared to other Vitamin C products I`ve used, is the texture and the fact that it absorbs very quickly. Most of the other serums I`ve tried have left a sticky residue and take a couple minutes to seep into the skin. This serum almost immediately dries down and does not leave any sort of residue on the skin. As someone who doesn`t like spending long periods of time on skincare and wants to move on to the next step ASAP, this serum is perfect. I`m looking forward to seeing what my skin will be like with continued use.

I've only been using this serum for three days (morning and night) but I can already see results. My skin looks clearer and feels smoother. The coloring is more even too. It's soft and it glows! We'll see if it continues to improve over time but for now I love it!

This product is amazing!! I have had acne as a kid to adult acne and most recently cystic acne and nothing has ever EVER worked. I have been using this product for 30 days now and my face and neck has never looked better. Acne scars are disappearing while texture is smoothing out. The key is to exfoliate 1x a week, use serum 3x a week, moisturize morning and evening and use the cleanser every day. I bought the whole set and I recommend using the entire set as your regimen if you suffer with sensitive skin and cystic acne.
