Absolutely great stuff… I’ve been using it for years now

One of the only Vit C serums I can find without Vit E (ALWAYS breaks me out) or Propranediol (too slick feeling). Affordable too. I ❤️ it!

Only used this a week but can see visible differences. Others are noticing... "You look so healthy and your skin is so clear." If this continues I plan to keep ordering this product. So far I am very very pleased. (I have very sensitive skin and cosmetics usually break me out; not this product).

After 35 years of buying nearly every available product out in the market, I must say that this one is by far the best! For a majority of my adult life, I struggled with acne and hated my skin. I finally gave in and did a 6 month treatment of Accutane which got rid of all my acne but left me with scars. I decided to use Obagi's 20% C-serum. It worked but made my skin so oily not to mention the nearly $100 price tag! Then I found NuFountain's C20 Ferulic serum. It has been a month of usage and I can't even begin to describe what this serum has done for my acne scars and overall texture of my face. It's amazing! It's so light and the effects are almost immediate.

I can tell they not only put a lot of care in producing their product but making sure it arrives as fresh as possible.

I have been a repeat customer of this product for years, so it's about time I review! First, the product is spectacular. With regular use , the texture of my skin improves - particularly relating to smoothness. I've also gifted this to several friends/family who have also been very happy with the product. I have very sensitive skin - it only tolerates the simplest of formulas, and I will say that this serum is elegant in that regard. It uses great ingredients but doesn't add in anything extraneous and for that I am very fortunate to find a product that does not irritate my skin (oily, very blackhead and inflammation prone). I appreciate their transparency regarding date formulated and instructions for use. Very important to keep vitamin C stable (the ferulic acid helps tremendously) and also to use a routine that takes into account photo-sensitivity (use sunscreen once absorbed). The shipping is lightning fast, too. Overall, NuFountain is very customer-centric in both their effective formulation, service, and pricing. This will continue to be my go-to serum!

"I LOVE this product.. Within a week I started to see a difference in my skin. I did a lot of shopping around before I purchased this product (LAA serum is expensive). NuFountain's price could not be beat... I will be ordering this product again"

I began using the C20 Brightening Serum almost a month ago and it has already proven to be a great skin care product. My skin has cleared up, the redness in my skin has lessened, and sun spots have begun to fade. I am absolutely amazed at how much better my skin looks. This is a skin care product that actually works. A rarity, indeed! Also, application is very easy. The serum is like water so 5-6 drops is all that is needed to cover the entire face. I will definitely buy again.

"I have never used LAA Serum before and had decided to try it after reading how great it is for your skin. I love how it gently exfoliates my skin without drying it. The price is reasonable, and I like that the serum is fresh."

I've used more expensive brands and I think this works as well. But I will say this seems more sensitive to light and air than the more expensive products. I use it generously on my face, neck and arms, so price point is very important to me, that's why I gave it five stars. Be sure to follow the directions about dispensing from dropper, and keep unused bottles in refrig. And use the product daily and generously, before it oxidizes. I heard dermatologists on t.v. say it was the single best thing one can use on their skin, and they weren't kidding.

Excellent product just give it time to work. It helps fade brown spots and plumps your skin with continuous use. People think I am 10 years younger. You do have to use sunscreen to help keep the brown spots away!

"I have spent soooo much $$ on products to improve my 54 yr. old skin, and this one, is THE BEST! Just 6 drops in the palm of my left hand, and I apply it with a finger from my right hand to face and neck every morning. After it has a couple of minutes to dry, I apply moisturizer. Usually a vitamin C cream. Sometimes my skin will need exfoliating after this procedure, before I apply my makeup. My skin showed dramatic improvement within weeks! My age spots have almost disappeared, and I've had no more pimples since I've been using this great product! I'm half-way through the bottle, and do not want to run out, so am back to purchase more. No more wasting $$ on products that promise what they can't deliver! :D!"

These guys are great by selling great products. Where else can you find Vitamin C with B3 cheaper than any company? This stuff is the real deal. Lightens my sun spots and reduced my previous acne scars and made them smoother and less noticeable. Will buy my 3rd order soon. Fast shipping too!

Skinceuticals was getting too expensive and irritated my neck. Googled replacement for Skinceuticals and this came out highly rated. No irritation and better smell. Will use again.

My aesthetician recommended this brand to me and my skin looks good. Better than Timeless which I also tried. My aesthetician much prefers Nufountain to Timeless and I agree. She says Nufountain “delivers” the vitamin C better and is better absorbed.
