So far I love this.

It brightened my face back up and my brown spots are starting to fade. I even used it on some keratosis and they are shrinking. My camera does not work well but trust me this does.

Smooth and glowy

I’m almost out of my first bottle and I noticed a big difference yesterday in my skin while looking in my car’s side mirror. Smooth and even is what I noticed. Now, I’m here ordering another bottle.

First time using Vitamin C!

In August 2020, I saw the advertisement on Instagram for Open Formula and decided with all the reviews that I would get the vitamin C for reducing dark spots on my face and to see if my face really did glow! And Guess what?...it does! The dark spots are slowly fading! I use the Open Formula retinol serum at night and the combo I think, is the winning ticket!

Free Radical Fighter!

If dark spots and fine lines are invading your skin, than this product is your go to for fighting these off! I am 37 yrs. old and have spent many years outside tanning, playing with my kids, volunteering outside events, SMOKING CIGARETTES, etc. and with all that uv exposure, and pollution, it took quite a toll on my skin. However, this Vitamin C serum has not only diminished my dark spots by brightening my skin, it has also given my face a plumper more youthful appearance in a very short amount of time.

**** Side note, this product worked well alone but when paired with the Retinol at night, the results were even better!

Second time purchasing

This is the second time I have ordered the Vitamin C serum. I really like it. I think it has helped with the appearance of my skin. I am 38 and have sun spots. I think it has helped lessen the darkness of the spots. I think it also makes my skin look more plump and hydrated. I have had zero reaction (breakouts) to the product.

I'm sold!

I’m 68 years old and have not been kind to my skin over the years. I am blonde and fair and tried for years to tan not realizing what I was doing to my skin, but I really believe by using this product I constantly get compliments on how pretty my skin is with any wrinkles!!!!!!! I have tried some very expensive products - with well-known names , and none have compared to this serum. I have to admit, I don’t just buy 1 at a time, but several so I stay in stock. Yes, I am truly SOLD on this item.
