Noticable Difference

I've tried every Vitamin C there is and I do notice a difference with this one more than others in terms of brightening up dark spots and melasma. The only draw back is the price (but thank goodness for dermstore's promotions! otherwise I wouldn't buy it) and it does sting and leave me slightly red with frequent use. Definitely works, though.

Completely Worth It

I love how this product has lightened my spots and naturally brightened my skin.  It is a high quality product and, for me, was worth the investment for the 20% C serum instead of the products with lower percentages because of the effectiveness.

Luminant Skincare

I purchased this as a possible replacement for skinceuiticals - while it's not (nothing quite reaches that level of effectiveness for my skin) it's very close and a good price point cheaper. There is a perfumed scent to it - but I can tell it makes a difference in brightening my skin and protecting it from damage.

Seems to work great

Very happy with this product. It's on the pricey side, but it's one of two products my dermatologist recommended, so I'm willing to shell out some $ for it.

Best Vitamin C

I noticed a huge difference from the first time I used this product. It's absolutely amazing and has my skin glowing! The redness from my rosacea has drastically reduced.

Decent but no holy grail

This vitamin C was okay, applied well with easy absorption. However I did not notice any difference when using this product and for it's price point I expected more. I try to use SkinCeuticals but because of price, I will swap brands every few months to keep more affordable. Not a terrible product but nothing to write home about.

LOVE THIS C!

I have tried several different brands of vitamin C and liked a few of them, but this one seems to have really stepped up the vitamin C game and made the most difference in skin brightness. I added it to my routine for battling my melasma and sun damage and I have noticed a visible difference when adding this with ZO 3 step peels, Lytera, and sunscreen for prevention. I am not a huge fan of the texture as it seems a little sticky compared to others I have tried, but with the results I can totally ignore that. Especially since it doesn't pill or have issues when mixed with other products in my routine! So glad I tried this!
