Blotchy skin used to make me 10 years older

“Very good product.

I deal with hyperpigmentation when I break out and this stuff keeps it under control more than any other product I’ve used which are quite a few.

It is liquid gold.

I use the retinoid serum afterwards, and the combination is just perfect for my skin”

– Amanda (Open Formula customer)

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.

Love this serum! I had been wanting to switch up my skin care route and stumbled upon this product. After doing some research on the benefits of a vitamin c serum I thought I would give it a try. I didn’t really have any specific issues with my skin but was just looking to switch things up. After about a week of using this I noticed a difference. It completely brightened up my completion and helped minimize my pores. I’ve gotten a ton of compliments on my skin recently! Love this! Will continue to use and highly recommend!

This is wonderful. I'm literally glowing all day with this. My skin was kinda pale and saggy. This serum revitalized my whole face. On my 3rd bottle now and have no intention of stopping any time soon.

For better skin

I have very pale skin so any blemish really shows up on my skin so I bought this and started using it right away.. it’s been a month and a half and my skin has looked so much better. My pores actually closed up and my skin actually looks hydrated (I have very dry skin). I use it in the morning, before makeup application and after a shower so I’m half way done but I’m for sure buying another.

Happy with my purchase

I never do reviews. That being said, this product does exactly what it is supposed to do. My skin is already changing after a few weeks of usage. I had left over faded red spots on my face from a season of acne I had 5 years ago. No product has improved those marks until now. My marks aren’t completely gone yet, but they are continuing to fade and I’ve been using the product for about a month. I will keep using because I am convinced that this is the key secret to glowing skin.
