The spots on my face and unevenness has gone with continuous usage. I use it atleast 3 times per week mixed with my moisturiser. This has brought a significant brightness to my face. 

Very potent as you can feel some slight stinging. Liquid Vitamin Cs decrease potency once the bottle opens. Easier to mix with thinner moisturisers.

Great product! Perfect as a boost of pure vitamin C to your mask or cream.

I love using this product mixed with the Inkey List Hyaluronic Acid and Drunk Elephant Protini moisturiser in the mornings. Need to find the right amount for your skin, and tangling at first is to be expected. But get the measurements right and it leaves skin feeling smooth and bright. A lot of product in the pot - I think it will last a long time! I love other more expensive Vitamin C products like Drunk Elephant C Firma serum, but this product feels strong and potent as well. Highly Recommend. 

I used to like The Ordinary. But I recently noticed that a few of their products caused me allergic reaction, including this one, and the AHA 30% + BHA 2% Peeling Solution. Areas around my mouth and eyes became painful, itchy, swollen and red. It took 2-3 days to get back to normal. I don't have allergy-prone skin and I have tried many different brands. This is the only brand and I am allergic to. I will not buy this brand anymore.

I have been using L-ascorbic acid from the Ordinary for years. This is the first time trying the powder version. It did take some getting used to. It doesn't mix well with all creams, with thicker creams the powder doesn't dissolve and i end up with a granular layer on my skin. With a gel based day cream it works perfectly for me. It does sting on application but it doesn't irritate my skin. You do have to add an extra step to your routine (mixing the powder) every day but to me it's worth the effort because the product works great and one jar last a long time.

I've been using this for just over a week now and I can see a huge difference in my skin. I haven't had any issues at all (except my hands have turned orange?). I have been using it alongside the Retinol 1% and they seem to be working really well together for my skin.

My favourite Vitamin C product so far! Must be careful not to use too much and also should not be mixed with certain products (such as acids, peptides, niacinamide, etc.). I prefer mixing it with The Ordinary's Natural Moisturising Factors cream or Squalane based granactive retinoids (right before using it, I mix it on my hand). Can also be mixed with water but I find that to be very messy. Should start using it at a small dose and once a week and increase it gradually (to avoid burns and such). It helps get rid of acne and also quite visibly brightens skin. I feel like I can see a difference immediately in the morning!

I mix it with my other serums for extra vitamin C benefits.

I like the powder - I notice my skin is much brighter. Will repurchase.
