Have been using for about a week and am surprised to already be noticing improvement in redness/little bumps on my chin that I've had for years. My skin looks healthier.

I did a lot of research looking for an EWG-approved Vitamin C that also doesn't oxidize quickly AND feels great on the skin. This serum is absolutely the best I've tried. I notice a big difference since I started using it. My skin is softer and more radiant when I use it regularly. "Radiant" is hard to describe but I guess I would say, my skin tone is more even, circulation seems better (brighter skin), and overall my skin looks healthier. I also have confidence that the Vit C is fighting free radicals throughout the day. I had a little snafu with one of my orders and their customer support team was amazing. They made it right and even sent a free bottle as an apology for the trouble, which was not necessary but an amazing gesture. This is a great product and a really nice company as well. Win-win.

After an extended search for a clean, effective vitamin C serum, I can confidently state that this product has exceeded my expectations. Since incorporating it into my skincare regimen, I have observed a noticeable improvement in the brightness, radiance, and overall health of my complexion. My skin appears more dewy and vibrant, and I frequently receive compliments.

One of the most significant benefits I have experienced is the visible reduction in the appearance of hyperpigmented areas, which now appear less pronounced. As someone with oily combination skin that is occasionally prone to acne, I have found the formulation to be lightweight and non-comedogenic. It does not exacerbate breakouts or contribute to congestion.

While the product can leave a slight sheen on the skin post-application, this has not been a deterrent in my experience. Overall, I am satisfied with the performance and results of this serum and would recommend it to individuals seeking a clean, efficacious vitamin C product.

I have used this product for 5 years now and I truly love it. It has evened out my skin and minimizes my hyperpigmentations. My skin still looks fairly youthful at the age of 45. It’s a definite must in my morning and night skin routine.

Another great product from Dr Louie. Nice smell and great for a sensitive skin. The size of bottle is small and run out guickly.
