WHERE HAVE YOU BEEN ALL MY LIFE

Love you Open Formula Vitamin C!!! How come you didn’t come out earlier because I could have saved my skin and saved so much money over the years. I used to use a Vitamin C and Ferulic Acid and it costs me well over $150 for one bottle. I saw the same ingredients in here and was blown away! Then I thought it wouldn’t work and it does-the same exact way! I know I wish it was earlier but I’m glad I found you now! I hope it doesn’t sound cheesy but if you’re reading this, get some Open Formula in your life!!!

GOOD FOR DAILY USE

I’ve been using this in the morning because I know Vitamin C is an antioxidant and I live in an urban area so there’s a lot of pollution. I feel like my skin looks brighter but that’s all. I don’t know what I expected this to do. I’m in my late 20’s so I would look at this as preventable anti aging. It’s like taking a daily vitamin to keep your body healthy.

NEW TO OPEN FORMULA BUT LOVING IT

I just started using Open Formula and I’m loving all of the products I have been using-the cleansers, serums, the mud mask is completely amazing! And I spent less than $20 and just another $20 for membership but for $40 I have a complete am/pm and weekly regime and I got to talk to their esthetician and she recommended a routine based on my skin concerns. How awesome is that - and for free! It’s never free to see a skin specialist and I’m not talking about the salesgirl at Sephora - a real, educated, experienced skin expert! She recommended this Vitamin C serum for daytime protection and we joked about the smell but I’ve seen a huge difference. My skin is brighter, healthier, this is so light I can use other serums with it. No burning, irritation, or breakouts. Seriously in love with this serum and Open Formula!!!

GREAT ADDITION TO MY PRODUCTS

Recently I’ve noticed my skin breaking out and getting bumpy. I already exfoliate so I thought maybe by adding a Vitamin C that it would help with other pollutants since I live in a big city. So glad I added this in. My breakouts are healing faster and are less and my skin feels really smooth now-no more bumpies! I like the other products and the price is great too!

SUN DAMAGE

I heard vitamin C was really effective at lightening sundamage sopts. I’ve been using this for about a month now and I haven’t seen a ton of improvement. My skin texture feels smooth and my skin looks healthier but my main concern is the sun spots that have recently come up. I used to tan a lot when I was younger and like overnight these dark spots have popped up so I’m a little disappointed that this didn’t work better.

GAME CHANGER

This Vitamin C is a game changer and just so everyone knows, vitamin C never smells good so you have to get past it but to know that it gives you protection, helps lighten and restore your skin, helps with aging and nasty environmental damage the smell is the least of your worries. The price is unbeatable for a true vitamin C that really works. So get a bottle of this powerful little miracle and change your skincare game!

BEST PRODUCTS I’VE USED

This is the best Vitamin C I’ve used and what a phenomenal price! Everyone needs to be using an awesome antioxidant like vitamin C everyday and they are usually so expensive so I could never invest the money it would take to have a real, effective vitamin C in my skincare regime. This even has Ferulic acid and Niacinamide which are also super expensive ingredients and I get all three for less than 5 bucks! I’m so beyond happy that I found Open Formula and now I have an incredible vitamin C that is improving my skin and protecting me.

HAS A SMOKEY SMELL

That’s funny a couple of people said a little goes a long way because I feel like I have to use more of it to cover my entire face as compared to other vitamin c serums I've used. I’m going through bottles pretty quickly. It’s nice to use fresh products all of the time and it’s not expensive but I thought it would last longer. It also has a weird smell! It’s almost smokey. It does make my skin look really nice, but not sure if I will buy again.

WOULD RECOMMEND FOR DARK SPOTS

A little bit of this goes a long way. I bought this to fade my dark spots from acne scars. The price is affordable and I can say 3 weeks of daily use some of my dark spots are starting to fade. I would recommend this to anyone with discoloration.
